Why Visual Performance Matters: Foundations for Occupational Therapy Practice

Housekeeping while people arrive.

Materials to have ready:

• Participation & Reflection Guide (printed or on screen)

• One client or student to think with for the whole session

• Pen and paper, or the reflection boxes in this player

• One referral or eye care report you have received

Housekeeping:

• Modules are self-paced; your place is saved as you go.

• Polls, reflections, and self-checks are participation supports — they do not affect your quiz score.

• Take a stretch break between modules; sustained near work is the topic, not the goal.

• The post-course exam and evaluation unlock after the last module.

Read the filed learning objectives verbatim — this is the AOTA-approved wording.

Objectives:

• Explain the developmental and anatomical basis of the visual system and articulate the occupational therapy practitioner's role in supporting visual function within the OT scope of practice.

• Differentiate ventral ("what") and dorsal ("where") visual pathway functions and identify classroom-based behavioral signatures associated with dysfunction in each pathway.

• Recognize clinical signs of visual conditions warranting referral to optometry, ophthalmology, or developmental vision specialists and distinguish them from findings addressable through OT intervention.

• Analyze comorbidity patterns between visual function deficits and autism, ADHD, dyslexia, and dysgraphia to inform integrated, occupation-based intervention planning.

• Apply a low-vision service delivery model, including environmental modification strategies, to support occupational performance for clients with reduced visual function.

• Construct an immediate next-step plan for a client with suspected visual performance limitations, sequencing clinical observation, occupation-based documentation, referral, and structured follow-up assessment within the OT scope of practice.

Explain how the session runs.

Schedule:

• Six modules, 3.0 contact hours total

• Each module: teach → show → reflect → self-check

• Post-course exam (80% to pass, unlimited retakes)

• Course evaluation, then certificate

How they participate:

• Opening poll in every module

• Think / Process / Share reflection prompts

• Case vignettes with referral and modification prompts

• One knowledge check per module

Transition: "Module 1."

Open here. "Why Visual Performance Matters." Vision is already on your caseload. The only question is whether it is named, measured, and treated.

Say why this section matters for their caseload, then advance.

Ask the poll: "When you see a visual concern in a student, how do you usually respond first?"

Options:

• I refer to the eye doctor and wait for results

• I observe in class and document what I see

• I start adaptation or intervention while also referring

• I assume the issue is already covered by the school vision screen

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "You are already treating vision."

Walk each point, one sentence each:

• Handwriting, reading endurance, board copying, dressing, feeding, mobility, play, driving, work simulation — every one routes through vision.

• When a practitioner says "vision is not my area," the visual contribution does not disappear. It gets renamed as attention, behavior, motivation, or motor planning.

• The plan of care is then built on the wrong variable — the most common reason a well-written visual-motor goal never moves.

• This is not a specialty. It is a competency inside occupational therapy.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "Understand → assess → intervene."

Walk each point, one sentence each:

• Understanding is not optional: vision is a client factor and a performance skill inside every occupational performance evaluation you already do.

• Understanding without assessment is a guess: "visual issues" in a report gives the team nothing to act on and nothing to re-measure.

• Assessment without intervention is abandonment: a profile that does not change Monday is documentation, not care.

• The Five-Level Framework and the VPA™ exist to close that loop — structured findings that point directly at an entry point for treatment.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Schools and clinics versus Universities and programs.

Schools and clinics:

• Schools: visual performance sits under reading, writing, accommodations, and state testing.

• Clinics: visual demands drive ADL independence, concussion recovery, and return to work or sport.

• Both need language a team can fund, act on, and re-test.

Universities and programs:

• Entry-level curricula still teach vision as anatomy and acuity.

• Graduates arrive able to name structures but not to describe visual performance in occupational terms.

• A shared framework gives faculty, fieldwork educators, and new grads one vocabulary.

Ask: "Which column is your student living in right now?"

Frame the slide: "Vision is the dominant channel for learning."

Walk each point, one sentence each:

• Classroom occupations are visually loaded: reading, copying, board work, worksheets, and navigation all route through vision (framing statement, Visual Minds Learning — not a prevalence figure).

• Visual demand dominates the school day, which is why an unstable visual system shows up as an academic problem first.

• Vision is not one skill — it is a gateway system that every other occupation is routed through.

• When the gateway is unstable, the deficit shows up everywhere: reading, writing, mobility, social participation.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "Why schools are required to respond."

Walk each point, one sentence each:

• IDEA covers school-age children whose qualifying condition adversely affects educational performance.

• Section 504 covers a broader group of "qualified handicapped" students, without requiring special education eligibility.

• OTs contribute functional, performance-based evidence that supports both pathways.

• Our documentation describes impact on occupation — it does not establish medical or ocular diagnosis.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Oculomotor and acuity versus Related development.

Oculomotor and acuity:

• Fixation and basic eye movements emerge by 2–3 months

• Good oculomotor control by ~2 years; complex control to age 9

• Acuity ~20/200–20/400 at 1–4 months, ~20/50 by 12–24 months, ~20/20 by 24–36 months

• Fine motor coordination and refined eye movement by 36–48 months

Related development:

• Color vision develops through 5–8 months, maturing gradually

• Depth perception and eye-hand coordination build 12–24 months

• Eye dominance emerges by age 4, more consistent by 7, mature by 12

• Dominance directs fixation and is as resistant to change as hand dominance

Ask: "Which column is your student living in right now?"

Talk over the visual: "Visual anatomy — the structures behind the function."

Say the caption in your own words: Cornea, lens, retina, optic nerve, chiasm, tracts, and visual cortex — the hardware that visual performance depends on.

Frame the slide: "Where OT sits relative to the eye care team."

Walk each point, one sentence each:

• Optometry and ophthalmology own refraction, ocular health, and diagnosis.

• OT owns the functional question: how does this student's visual system perform inside real occupations?

• We describe observed performance, conditions, and occupational impact — never a diagnosis or a lens prescription.

• Every visual finding in this course is framed as "recognize and refer," not "diagnose and treat."

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Talk over the visual: "Two lanes, one student."

Say the caption in your own words: Medical eye care owns diagnosis and the optical correction; OT owns performance inside real occupations. The referral and the task modification run in parallel, on the same day.

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Read the scenario aloud, slowly:

A kindergarten teacher reports that a student "just isn't paying attention" during calendar time and often bumps into classmates during transitions. The student passed a school vision screening six months ago.

Then put these questions to the room:

• What visual-performance questions would you want answered before assuming this is an attention or behavior issue?

• What is the one sentence you would write in a consult note, and what referral would run in parallel?

Give 60 seconds of think time before you take answers. Model answers are in the panel beside this script.

Describe what belongs here: The referral question, the occupation it interrupts, and who else is already involved..

Land the "so what": A distance acuity screening answers one question at one distance. Nearly every school task the student is failing happens at 40 cm, under time pressure, with both eyes working together.

Explain the mechanism plainly: Screenings are built to catch reduced acuity, not efficiency, endurance, or integration.

Then give them the moves — say each one as something they can do Monday:

• Ask what the screening actually measured before accepting it as a clearance.

• Observe the student in the failing occupation, at the real distance and duration.

• Refer when a sign is undiagnosed, even if the screening was passed.

Tell them what success looks like: Performance that falls apart only under sustained near demand — a screening will never show you that.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Two-minute case. Read it aloud:

A teacher forwards a screening result of 20/20 in each eye and says "so it is not her vision."

Put the question to them: "What is your one-sentence reply, and what do you do next?" Give 60 seconds, no talking.

Model answer (reveal after they commit): "That tells us she can resolve detail at distance; it does not tell us how her eyes hold up at 40 cm for twenty minutes." Then observe a real near task at real duration and document what changes with time on task.

Close with the rule: Distance acuity is a floor, not a clearance.

Reflection prompt: "Think about a referral you received that mentioned a visual concern. What did you own as OT, and what did you defer to eye care?"

Cues:

• Name one observation you could write in occupational terms.

• Name one thing you would not write because it is outside OT scope.

Offer the sentence starter: "I own the occupational observation that... I defer to eye care the question of whether..."

Think for one minute, write, then take two shares.

Knowledge check: "A first-grade student holds books at 10 cm and squints. The school vision screen was passed. Which statement is most appropriate for your OT note?"

Options:

• Student has convergence insufficiency and needs vision therapy.

• Student passes vision screen; no visual concerns noted.

• Student reads at 10 cm working distance with squinting; refer for comprehensive eye exam and adapt materials in the meantime.

• Student requires reading glasses before starting OT intervention.

Correct answer: option 3. Rationale: The OT describes observable performance and working distance, recommends referral, and continues adaptation. Diagnosis, therapy prescriptions, and optical recommendations belong to eye care.

Transition: "Module 2."

Open here. "The Visual Pathways." Ventral "what" vs. dorsal "where," and their classroom signatures.

Say why this section matters for their caseload, then advance.

Ask the poll: "Which visual performance patterns show up most in your current caseload?"

Options:

• Slow recognition of letters, words, or symbols

• Losing place, bumping into things, misjudging space

• Both identification and spatial problems

• I am not sure how to tell the difference

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Talk over the visual: "Two streams, one retina."

Say the caption in your own words: Retina → optic nerve → chiasm → LGN → V1, then divergence: dorsal superiorly to parietal cortex, ventral inferiorly to temporal cortex (Visual Minds Learning clinical education).

Talk over the visual: "Parvocellular and magnocellular tracts."

Say the caption in your own words: Parvocellular cells carry fine detail and color into the ventral stream; magnocellular cells carry motion and low-contrast information into the dorsal stream.

Talk over the visual: "Vision's Two Highways."

Say the caption in your own words: The magnocellular highway (motion, contrast, spatial awareness, action) and the parvocellular highway (detail, color, form, recognition) merge at the LGN before diverging into the dorsal and ventral streams.

Talk over the visual: "Vision's two highways in the school day."

Say the caption in your own words: Ventral "what" signs versus dorsal "where" signs, side by side with the classroom behaviors each one produces.

Contrast the two columns: Ventral stream — "What?" versus Dorsal stream — "Where?".

Ventral stream — "What?":

• Parvocellular tract

• Object identity, color, size, fine detail

• Supports letter/word recognition and object identification

• Deficits show up as slow or inaccurate visual identification

Dorsal stream — "Where?":

• Magnocellular tract

• Spatial orientation, mapping, posture, balance

• Supports locating items in space and guiding movement toward them

• Deficits show up as spatial, postural, and navigation errors

Ask: "Which column is your student living in right now?"

Frame the slide: "What a ventral-stream (parvocellular) signature looks like in class."

Walk each point, one sentence each:

• Slow, effortful recognition of letters, sight words, or numerals

• Confusing visually similar letters or symbols beyond the expected age

• Difficulty matching an object to its picture or naming what was just seen

• Strong performance on movement-based tasks but weak on detail/identification tasks

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "What a dorsal-stream (magnocellular) signature looks like in class."

Walk each point, one sentence each:

• Bumping into furniture, misjudging distances, poor spatial awareness in the room

• Difficulty locating an item visually even when it is in plain sight

• Trouble copying spatial layouts — maps, graphs, math columns, diagrams

• Balance, posture, or motor-planning concerns alongside the visual complaint

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "We do not treat tracts — we treat the functional components."

Walk each point, one sentence each:

• The magnocellular and parvocellular tracts describe transmission: how visual information travels from retina to cortex. That is anatomy and physiology, and it is outside what OT assesses or changes.

• OT works one layer up, on the functional components the tract supports — fixation stability, saccadic accuracy, place-keeping, contrast and motion tolerance, discrimination, visual memory.

• The intervention target is always a functional component plus the task and environment: contrast and print adaptation, graded near-work load, pacing, reduced visual clutter, compensatory access.

• Never write, say, or imply that OT intervention improves, trains, strengthens, or repairs a pathway, or that a VPA™ result identifies a magnocellular deficit.

• The measured outcome stays in the occupation — reading the passage, copying the assignment, crossing the parking lot — not in the pathway.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Run the five levels bottom-up.

Spend your time on Level 3 — that is the point of this slide.

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Talk over the visual: "Beyond 20/20 — the Visual Performance System™."

Say the caption in your own words: Level 1 Visual Access → Level 2 Visual Efficiency → Level 3 Visual Processing → Level 4 Visual-Motor Integration → Level 5 Functional Integration.

Read the scenario aloud, slowly:

A 3rd-grade student reads individual words accurately in isolation but cannot find her place after looking up from the page, and she frequently loses items placed directly in front of her on a busy desk.

Then put these questions to the room:

• Which stream does this description sound more consistent with, and what would you probe next to confirm it?

• How would you phrase this finding for a teacher without naming a "dorsal stream deficit"?

Give 60 seconds of think time before you take answers. Model answers are in the panel beside this script.

Set up the contrast: "What a spatial ("where") breakdown looks like on the page."

Point at the before panel first. The student has to generate placement, size, and direction with no external structure.

Then the after panel. Same sentence, same student, with baseline and line-to-line reference restored.

Say the rule out loud: When performance changes because the environment supplied the spatial reference, you are looking at a spatial ("where") demand, not a word-knowledge ("what") problem.

Ask: "What did we change — the child, or the demand?"

Land the "so what": You will almost never be handed a vision complaint. You will be handed avoidance, sloppiness, slowness, or "not trying."

Explain the mechanism plainly: Children rarely report a visual world they have always had. They report what it costs them, in behavior.

Then give them the moves — say each one as something they can do Monday:

• Translate the referral complaint into an observable visual demand.

• Compare performance across distance, duration, and layout before judging effort.

• Give the team the behavioral signature in writing so it stops being a character description.

Tell them what success looks like: Consistent avoidance of one occupation while a similar-difficulty task with lower visual load is fine.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Set up the contrast: "Postural setup changes what you are measuring."

Point at the before panel first. Feet unsupported, trunk collapsed, page about 15 cm from the eyes.

Then the after panel. Feet supported, hips back, page raised toward a slant, working distance near Harmon distance.

Say the rule out loud: Fix posture and distance before you score anything. Otherwise you are documenting the setup, not the student.

Ask: "What did we change — the child, or the demand?"

Two-minute case. Read it aloud:

A Grade 3 student completes math facts on a whiteboard quickly, but produces almost nothing on the same problems given as a dense worksheet.

Put the question to them: "What does that difference tell you, and what do you trial first?" Give 60 seconds, no talking.

Model answer (reveal after they commit): The math skill is intact; the visual demand of the page is the variable. Trial the same items with enlarged print, fewer items per page, and a line guide. If output normalizes, document a demand mismatch and modify the page while you investigate efficiency.

Close with the rule: When the same content succeeds in one visual format and fails in another, look at the format first.

Reflection prompt: "Choose one student. Describe one behavior that looks like a "what" problem and one that looks like a "where" problem."

Cues:

• Use only the language of classroom performance, not stream labels.

Offer the sentence starter: "A "what" problem looks like... A "where" problem looks like..."

Think for one minute, write, then take two shares.

Knowledge check: "A student reads words accurately but cannot copy from a spatial diagram. Which description fits best?"

Options:

• Ventral stream problem — difficulty identifying details

• Dorsal stream problem — difficulty with spatial layout and mapping

• Both streams are equally affected

• The student is not trying hard enough

Correct answer: option 2. Rationale: Difficulty copying spatial layouts, maps, and diagrams is consistent with a dorsal / spatial-mapping pattern. Accurate word reading suggests the ventral identification stream is relatively intact.

Transition: "Module 3."

Open here. "Underlying Conditions vs. Functional Limitations." The eye and brain conditions that may sit under what you observe — and the functional problems OT actually treats.

Say why this section matters for their caseload, then advance.

Ask the poll: "Which condition are you least confident recognizing functionally?"

Options:

• Cortical Visual Impairment (CVI)

• Amblyopia / strabismus

• Convergence problems

• Albinism / ONH / coloboma

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "How to use this module."

Walk each point, one sentence each:

• These are possible underlying diagnoses, not OT findings — diagnosis belongs to ophthalmology, optometry, and neurology.

• OT does not diagnose or treat the condition; OT describes and treats the functional limitation it produces.

• The point is vocabulary and mechanism: knowing the condition tells you what ceiling you are working under and which supports are worth trying.

• A short red-flag list still warrants prompt medical eye care, and OT intervention continues in parallel either way.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: What it is versus Functional limitations OT treats.

What it is:

• Brain-based, not ocular — the eye exam is often normal

• A visual-processing problem, not low vision

• Often described as a "kaleidoscope" visual experience

Functional limitations OT treats:

• Strong color preference

• Vision improves with movement or positioning

• Visual latency — delayed response

• Breaks down in visual clutter

Ask: "Which column is your student living in right now?"

Contrast the two columns: What it is versus Functional limitations OT treats.

What it is:

• Congenital under-development of the optic nerve

• Prenatal drug or alcohol exposure is commonly cited

• Ranges from mild nerve dysfunction to complete loss

• Frequently presents with autistic-like behaviors — light gazing, stereotypies, social-gaze differences

Functional limitations OT treats:

• Acuity and field loss — print size, contrast, materials placement

• Performance varies by lighting and setting; one acuity number does not predict the day

• Near-work endurance and visual attention

• Autistic-like behaviors are described functionally, never diagnosed by OT

Ask: "Which column is your student living in right now?"

Contrast the two columns: Strabismus versus Amblyopia.

Strabismus:

• Eyes are not aligned with one another; can be congenital or acquired

• Creates a double image the CNS may suppress from one eye ("sensory suppression")

• Can present as a phoria (fusion holds it in check, but effortful) or a tropia (constant, observable deviation)

• Phoria drives visual stress, reduced concentration, slowed reading, and headaches even without a visible turn

Amblyopia:

• Functional "blindness" in central vision from ongoing sensory suppression

• Significantly reduced acuity in the suppressed eye

• Impairs binocular vision — eyes do not work together effectively for daily tasks

• Timing matters medically: the treatment window narrows with age, so an unexamined eye turn is worth naming in your report

Ask: "Which column is your student living in right now?"

Frame the slide: "Naming the direction — vocabulary, not diagnosis."

Walk each point, one sentence each:

• Esotropia — eye turns inward.

• Exotropia — eye turns outward.

• Hypertropia — eye turns upward.

• Hypotropia — eye turns downward.

• OTs may describe an observed eye position; the eye care team confirms and classifies the diagnosis.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Ocular albinism versus Nystagmus.

Ocular albinism:

• Hereditary condition; excess light enters through an unpigmented iris

• Reduced visual acuity and severe photophobia

• Frequently co-occurs with nystagmus and severe astigmatism

Nystagmus:

• Involuntary, rhythmic eye movement — horizontal, vertical, or torsional

• Reduces acuity through poor gaze stability; often experienced as blur

• Rarely isolated — seen with albinism, cataract, optic atrophy, vestibular/cerebellar or brain-injury involvement

• Some individuals find a "null point" head position that improves stability and acuity

Ask: "Which column is your student living in right now?"

Contrast the two columns: Retinopathy of Prematurity & Retinitis Pigmentosa versus Congenital cataracts.

Retinopathy of Prematurity & Retinitis Pigmentosa:

• ROP: abnormal blood vessel growth unique to preterm infants; incidence approaches 100% in the smallest, lowest-birth-weight infants

• RP: inherited, progressive rod-cell loss beginning mid-periphery ("donut" pattern), progressing centrally and peripherally over years

• Both carry a progressive or high-risk course — flag for ongoing ophthalmologic monitoring

Congenital cataracts:

• Present at birth; causes include genetic factors and in-utero exposures (e.g., rubella)

• Most are non-progressive and many do not cause significant impairment

• Bilateral, significant cataracts are typically removed within the first two months of life

• Intra-ocular lens replacement is not used in infancy; corrective lenses or contacts follow surgery

Ask: "Which column is your student living in right now?"

Contrast the two columns: What the diagnosis tells you versus What you write and treat.

What the diagnosis tells you:

• Reduced acuity — detail is limited

• Field loss — part of the world is unavailable

• Photophobia — light load is intolerable

• Unstable fixation or misalignment

• Complexity intolerance (CVI)

What you write and treat:

• Print size, contrast, working distance

• Scanning and placement in the usable field

• Lighting, glare control, seating

• Near-work endurance, tracking, place-keeping

• Array density and response latency

Ask: "Which column is your student living in right now?"

Read the scenario aloud, slowly:

A 2nd-grade student passed a school acuity screening this year. In therapy, he tilts his head to one side while reading, occasionally reports "things look blurry and double," and squints in bright hallway light.

Then put these questions to the room:

• Which underlying conditions could plausibly produce this picture, and which of them would a passed acuity screen fail to detect?

• Write the one sentence of documentation that names the functional limitation you will treat, without naming a diagnosis.

Give 60 seconds of think time before you take answers. Model answers are in the panel beside this script.

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Contrast the two columns: Diagnosed and managed → OT addresses it versus Undiagnosed, unclear, or changing → refer.

Diagnosed and managed → OT addresses it:

• Low acuity: magnification, enlarged print, working distance, seating.

• Contrast loss: bold-line paper, reverse polarity, glare control.

• Field loss: systematic scanning, anchoring, materials in the intact field.

• The OT target is the limitation, never the eye condition.

Undiagnosed, unclear, or changing → refer:

• No comprehensive exam on file, or correction unworn or outgrown.

• A functional loss no one has evaluated, or one that does not match the diagnosis.

• Anything new: eye turn, double vision, field complaint, pain.

• Refer and keep working — the modification goes in today.

Ask: "Which column is your student living in right now?"

Contrast the two columns: Refer promptly versus OT continues in parallel.

Refer promptly:

• New or intermittent eye turn, head tilt, or double vision

• Sudden acuity change, eye pain, or light sensitivity that is new

• No comprehensive eye exam on file, or glasses outgrown or unworn

• Function that does not match the documented diagnosis

OT continues in parallel:

• Print size, contrast, and lighting adjusted today

• Scanning, place-keeping, and copying strategies taught

• Near-work endurance graded and monitored

• Functional observations documented for the eye care report

Ask: "Which column is your student living in right now?"

Land the "so what": Some findings move to the front of the line the day you see them; most do not. Knowing which is which protects the student and your scope.

Explain the mechanism plainly: Pain, sudden change, new diplopia, new head tilt, or an unexplained acuity drop are same-day referrals regardless of caseload.

Then give them the moves — say each one as something they can do Monday:

• Keep the same-day list somewhere you can see it during observations.

• Refer and document on the same day for those findings.

• Continue OT services alongside the referral, never instead of it.

Tell them what success looks like: A new sign in a student you already know — change is more informative than a static finding.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Two-minute case. Read it aloud:

During a Thursday session, a student you have treated for months suddenly holds his head tilted to the right and reports "two of things" when he looks at the board.

Put the question to them: "What is your action today?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Same-day referral: new head tilt plus new diplopia. Notify the family and the school nurse today, document the observation in performance language, do not attempt to characterize the deviation, and keep your session plan for the tasks he can currently do safely.

Close with the rule: New, sudden, or changing signs are urgent regardless of what you have already ruled out.

Reflection prompt: "Write a one-sentence referral note for a student you suspect may have a visual condition that needs eye care. Include only what you observed and why it matters."

Offer the sentence starter: "During [activity], [student] was observed... This matters because it affects..."

Think for one minute, write, then take two shares.

Knowledge check: "Which finding requires the most urgent referral?"

Options:

• A student who reads slowly with large print

• A student who reports sudden double vision after a playground fall

• A student who prefers a specific color highlight

• A student who squints when looking at the board

Correct answer: option 2. Rationale: Sudden double vision after head trauma is an ocular/neurological red flag requiring urgent evaluation. The other findings warrant attention but are not same-day emergencies.

Transition: "Module 4."

Open here. "Comorbidity Patterns." Autism, ADHD, dyslexia, and dysgraphia — visual performance signs, not causation.

Say why this section matters for their caseload, then advance.

Ask the poll: "In your practice, when a student has a diagnosis like ADHD or dyslexia, how often is a visual contribution also checked?"

Options:

• Always

• Usually

• Rarely

• Never

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Association is not causation."

Walk each point, one sentence each:

• These four conditions frequently co-occur with visual performance differences — the visual finding does not cause the diagnosis.

• OT describes the visual sign and its occupational impact; OT does not attribute a diagnosis to a visual cause.

• About 1 in 4 school-age children may have an undiagnosed vision problem affecting academics (Kleinstein et al., 2003, CLEERE).

• These patterns raise suspicion for a referral — they do not replace one.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: What is reported versus Occupational impact.

What is reported:

• Reduced eye contact or difficulty sustaining visual focus

• Difficulty tracking moving objects

• Visual hypersensitivity; avoids visually busy settings

• Figure-ground difficulty in cluttered environments

Occupational impact:

• Face recognition and disorganization with visual materials

• Reduced reading of expressions and nonverbal cues

• Strabismus reported at 1.8–8.3% in autism (Holhoș et al., 2022) — association only

• Magnocellular associations reported; mechanism unsettled

Ask: "Which column is your student living in right now?"

Contrast the two columns: What is reported versus Occupational impact.

What is reported:

• Difficulty sustaining focus on visual tasks; easily distracted

• Struggles tracking words across a page; frequent place loss

• Trouble filtering important visual details from background clutter

Occupational impact:

• Difficulty recalling visual details; needs repetition to interpret visual information

• Impulsive, rushed visual task completion with disorganized output

• ~16% report an unspecified vision problem (Bellato et al., 2023, systematic review); higher reported likelihood of convergence issues (Koscinski, 2022, narrative review) — co-occurrence only, not causation

Ask: "Which column is your student living in right now?"

Contrast the two columns: What is reported versus Reported associations.

What is reported:

• Letter or number reversals; misaligned text or math columns

• Difficulty focusing on relevant text amid a page (figure-ground)

• Difficulty following lines of text; challenges with saccadic movement

• Struggles recalling letter order or spelling from visual memory

Reported associations:

• 73% show deficits in at least one visual-processing domain (reported in the dyslexia visual-processing literature; observational samples, not a population prevalence)

• 63% show unstable eye dominance (same observational literature)

• Significant magnocellular correlation reported (Greatrex et al., observational)

• AAP / AAO / AAPOS joint statement: dyslexia is a language-based disorder; visual findings are correlates, not causes, and vision treatment is not a treatment for dyslexia

Ask: "Which column is your student living in right now?"

Frame the slide: "Visual performance signs associated with dysgraphia."

Walk each point, one sentence each:

• Illegible handwriting; struggles with letter formation, alignment, and spacing.

• Difficulty sustaining visual attention on writing tasks, producing incomplete or messy work.

• Frustration on precision visual-motor tasks such as drawing shapes or copying diagrams.

• This is a Level 4 visual-motor integration signature in a structured visual performance framework, treatable directly in OT — the framework that defines these levels is taught in Course 1.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "The numbers behind the urgency."

Walk each point, one sentence each:

• 1 in 4 school-age children are estimated to have an undiagnosed vision problem affecting academics (Kleinstein et al., 2003, population-based cohort).

• 6.8% of children under 18 have a diagnosed visual condition; 3% are blind or visually impaired (CDC surveillance data). These are co-occurrence figures, not causal claims.

• A visual performance sign inside any of these four diagnoses is a prompt for OT documentation and referral — not for OT diagnosis of the visual disorder.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Read the scenario aloud, slowly:

A 5th-grade student with an ADHD diagnosis is referred for "poor handwriting and inattention." During your session he loses his place three times in one paragraph and cannot locate his pencil among other items on the desk.

Then put these questions to the room:

• Which findings are visual-performance signs worth documenting separately from the ADHD diagnosis?

• What would your present-level sentence say, and what referral (if any) would accompany it?

Give 60 seconds of think time before you take answers. Model answers are in the panel beside this script.

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Set up the contrast: "A visual-motor signature on the page — and what changed it."

Point at the before panel first. Same student, same words, no external spatial structure.

Then the after panel. The visual boundary is supplied by the page instead of held in the head.

Say the rule out loud: This is a spacing, alignment, and formation problem — a visual-motor integration signature — not a motivation or handwriting-instruction problem. Document what you observed, modify the page today, and refer if no eye exam is on file.

Ask: "What did we change — the child, or the demand?"

Land the "so what": Autism, ADHD, dyslexia, and dysgraphia all produce behavior that overlaps with visual-performance findings. Treating one and ignoring the other stalls the student.

Explain the mechanism plainly: Overlapping presentations share observable behavior but differ in the conditions that change performance.

Then give them the moves — say each one as something they can do Monday:

• Manipulate one visual condition and see whether performance moves.

• Keep both hypotheses alive in your documentation instead of choosing early.

• Coordinate with the SLP, teacher, and psychologist on what each of you is testing.

Tell them what success looks like: Performance that changes with a visual manipulation but not with an attention support, or the reverse.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Set up the contrast: "Task layout: dense page versus spaced page."

Point at the before panel first. Small print, tight leading, items packed edge to edge.

Then the after panel. Larger print, wide line spacing, fewer items per page, clear margin cue.

Say the rule out loud: Spacing is not an accommodation for content; the reading or math demand is unchanged. Only the visual-efficiency load moved.

Ask: "What did we change — the child, or the demand?"

Two-minute case. Read it aloud:

A Grade 4 student with an ADHD diagnosis loses his place while reading, skips lines, and finishes about half the passage. Medication is stable and he sustains attention well in a listening task.

Put the question to them: "How do you decide whether the reading breakdown is visual?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Manipulate the visual variable, not the attention variable: same passage with a line guide, larger print, and fewer lines per page. If place-losing and completion improve without any attention support changing, you have a visual-efficiency contribution to document alongside the ADHD.

Close with the rule: Co-occurring diagnoses do not cancel each other. Change one condition at a time and let performance answer.

Reflection prompt: "Think about a student with a comorbid diagnosis. What one visual performance question would you add to the evaluation or IEP meeting?"

Offer the sentence starter: "I will ask: "When [student] does [occupation], what visual demand is hardest to meet?""

Think for one minute, write, then take two shares.

Knowledge check: "Which statement about dyslexia and vision is supported by evidence?"

Options:

• Dyslexia is caused by visual tracking problems and can be cured with eye exercises.

• Dyslexia is language-based; some students may also have co-occurring visual efficiency problems that need separate care.

• Colored overlays are the first-line treatment for dyslexia.

• OTs should not address visual-motor issues in students with dyslexia.

Correct answer: option 2. Rationale: Major pediatric and ophthalmology organizations agree that dyslexia is language-based. Some students may also have visual efficiency concerns, and those should be addressed by the appropriate provider while reading intervention targets the language deficit.

Transition: "Module 5."

Open here. "The Low-Vision Service Model." Usable vs. non-usable vision, and the environmental modifications that change performance today.

Say why this section matters for their caseload, then advance.

Ask the poll: "Which low-vision strategies have you already used?"

Options:

• Increased lighting or contrast

• Magnification or larger print

• Text-to-speech or audio support

• Tactile or non-visual substitution

• None of these yet

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Two categories of clients drive two different plans."

Walk each point, one sentence each:

• Usable vision — the client can still use residual vision functionally with the right supports.

• Non-usable vision — vision cannot be relied on as the primary channel; other senses and strategies carry the task.

• For vision users: increase visibility, enhance visual components, and augment with other sensory input.

• The same environment can be modified for both groups at once — lighting and contrast changes rarely conflict.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Environment versus The page.

Environment:

• Preferential seating closer to the front / instructional materials

• Appropriate lighting; avoid glare; face away from windows

• Minimize patterned backgrounds and visual clutter

• Encourage large, bold, black-marker writing on whiteboards

The page:

• Enlarge text; use large print where possible

• Maximize print contrast — black on white or white on black

• Use a familiar, bold typeface; avoid decorative or superfluous fonts

• Provide high-contrast stickers or labels for materials

Ask: "Which column is your student living in right now?"

Frame the slide: "Lighting is a modifiable variable, not a fixed constraint."

Walk each point, one sentence each:

• Light from behind, over the shoulder, close to the reading surface — avoid shadowing.

• Use full-spectrum lighting where possible; avoid glossy paper that creates glare.

• Use typoscopes (line-isolation windows) and colored overlays/filters when they measurably improve performance.

• Improper lighting causes glare, shadows, and strain that compound both low vision and visual-processing deficits.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Real-world contrast values versus What this means for classrooms.

Real-world contrast values:

• Exit sign: ~80% contrast

• Newspaper print: ~71–75% contrast

• Currency: ~55–60% contrast

• Gray car in shade: ~32% contrast

• Maroon chair on maroon carpet: ~5% contrast

What this means for classrooms:

• Everyday materials sit far below the contrast a low-vision student needs

• High-contrast worksheets change access, not just comfort

• Contrast-sensitivity tools (e.g., Lea Low Contrast Chart) quantify it

• Pair contrast fixes with figure-ground support

Ask: "Which column is your student living in right now?"

Talk over the visual: "What those contrast values actually look like."

Say the caption in your own words: The same worksheet line at ~90%, ~70%, ~40%, and ~10% contrast, plus reverse and tinted variants — hold a student handout next to these before assuming the print is usable.

Talk over the visual: "Magnification options, side by side."

Say the caption in your own words: Handheld, stand, spectacle/telescope, electronic (CCTV), and built-in digital magnification — each with its own working distance and field trade-off.

Frame the slide: "Low vision: what OT addresses, and when OT refers."

Walk each point, one sentence each:

• Diagnosed acuity loss: magnify, enlarge, control working distance, seat for the task.

• Documented contrast loss: high-contrast materials, bold-line paper, glare control.

• Documented field loss: scanning patterns, anchoring, materials in the intact field, O&M collaboration.

• Refer when the loss is undiagnosed, correction is unverified, or anything is new or worsening.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Optical and electronic magnification versus Everyday and digital AT.

Optical and electronic magnification:

• Handheld, stand, and hands-free magnifiers for near tasks

• Telescopes (binocular or monocular) for distance viewing

• Electronic magnification (desktop or portable) adds adjustable contrast and screen-reader options

• Stronger magnifiers require shorter focal distances — fit to task, not preference alone

Everyday and digital AT:

• Built-in phone/tablet accessibility features: text enlargement, voice-over, magnifier

• Screen magnifiers/readers (e.g., ZoomText, JAWS); text-to-speech and speech-to-text apps

• Slant boards to reduce glare and improve writing visibility

• Contrast tape on steps/furniture edges; tactile graphics for spatial tasks

Ask: "Which column is your student living in right now?"

Frame the slide: "Organization, mobility, and multisensory support."

Walk each point, one sentence each:

• Teach organization strategies (one master notebook, home/school large-print duplicates, time management).

• Refer to Orientation & Mobility (O&M) specialists when mobility or navigation is affected; allow extra transition time.

• Augment with tactile cues (markings on notebooks, tactile technology cues) and auditory input (screen readers, voice-to-text).

• Multisensory pairing — visual instruction plus verbal or tactile cues — supports both low-vision and visual-processing needs simultaneously.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Read the scenario aloud, slowly:

A student has documented low vision (usable, functional vision with correction) and a separate visual-processing profile with figure-ground weakness. The IEP team asks for one classroom modification plan.

Then put these questions to the room:

• Which three modifications from this module serve both profiles at once?

• What would you measure before and after the modifications to show they worked?

Give 60 seconds of think time before you take answers. Model answers are in the panel beside this script.

Set up the contrast: "Paper choice is a visual support."

Point at the before panel first. Two lines define one body space, so the writing target is on the page instead of in the head.

Then the after panel. A high-contrast band fills the body space; the baseline becomes a boundary, not a guess.

Say the rule out loud: Two-line paper is already a visual support; highlighting the body space adds contrast for students with documented access needs. Plain or three-line paper is the confusing option. Both of these are Level 1 access modifications you can put on the desk today.

Ask: "What did we change — the child, or the demand?"

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Talk over the visual: "Where low vision sits in the framework."

Say the caption in your own words: Low vision is a Level 1 access problem. Contrast, lighting, and magnification restore the floor so the higher levels can be measured at all.

Land the "so what": When you change the environment and output improves the same day, you have learned something about the student, not just helped them.

Explain the mechanism plainly: A demand mismatch responds immediately to a change in demand; a capacity limit does not.

Then give them the moves — say each one as something they can do Monday:

• Change one variable — clutter, layout, distance, or lighting — and record the result.

• Give the teacher one modification, not five, so the result is interpretable.

• Write the response to modification into your reasoning as evidence.

Tell them what success looks like: No change after a clean modification trial — escalate to structured assessment.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Set up the contrast: "Visual clutter: the same student, two desks."

Point at the before panel first. Overlapping papers, patterned surface, busy wall directly behind the work.

Then the after panel. One page, one tool, plain background, work placed in midline.

Say the rule out loud: Change one variable at a time. If output improves with clutter removed, you have found a demand problem, not a capacity problem.

Ask: "What did we change — the child, or the demand?"

Two-minute case. Read it aloud:

You want to help a student who cannot copy from the board. The teacher offers to move his seat, enlarge the print, give him a printed copy, and add a slant board all at once.

Put the question to them: "What do you ask her to do instead, and why?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Start with the printed near copy alone for a week and record completion, because it removes the far-to-near transition entirely. If output normalizes, the far-near shift is the demand; if it does not, add the next single change. Bundling four modifications gives you a happier student and no information.

Close with the rule: Stack modifications for support, but trial them one at a time when you need an answer.

Reflection prompt: "Choose one occupation from your caseload or life. Describe one modification at each of the four low-vision levels for that occupation."

Offer the sentence starter: "For [occupation]: increasing visibility means... enhancing the signal means... substitution means..."

Think for one minute, write, then take two shares.

Knowledge check: "Which strategy is an example of "enhancing" the visual signal?"

Options:

• Adding a desk lamp

• Using a handheld magnifier

• Listening to an audiobook instead of reading

• Adding high-contrast tape to stairs

Correct answer: option 2. Rationale: Enhancing the signal means magnifying the target or bringing it closer. Adding light is increasing visibility; audiobooks are substitution; high-contrast tape is increasing visibility.

Transition: "Module 6."

Open here. "Where This Goes Next." From observation to structure, and from structure to measurement.

Say why this section matters for their caseload, then advance.

Ask the poll: "After today, what is your honest next step with visual performance?"

Options:

• Start describing it in my notes this week

• Make one modification and watch what happens

• Write a referral I have been putting off

• Learn a structured framework before I change anything

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Five blocks in, here is the skill set."

Walk each point, one sentence each:

• You can describe visual performance in occupational language instead of diagnostic language.

• You can sort a red flag from an OT-addressable finding and refer without hesitating.

• You can recognize when autism, ADHD, dyslexia, or dysgraphia is shaping the visual picture.

• You can change the environment and the task so the student or client can work today.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Talk over the visual: "Which level each block of this course was operating on."

Say the caption in your own words: Blocks 1–6 mapped to the five-level framework, so your documentation language matches the level the finding actually came from.

Frame the slide: "Observation alone is unordered."

Walk each point, one sentence each:

• Two therapists watching the same client notice different things and prioritize differently.

• "Why did you target this first?" has no defensible answer without a sequence.

• Progress statements built on impressions do not hold up in an IEP meeting or a payer review.

• What is missing is structure — a defined relationship between findings.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: What it does versus What it is not.

What it does:

• Tells you where to look first, because foundational levels constrain higher ones

• Tells you what a finding means based on where it sits

• Gives you sequencing language for documentation

What it is not:

• Not a diagnosis and not a substitute for the eye exam

• Not a replacement for observation — it organizes observation

• Not taught in this course; it is the next stage of the sequence

Ask: "Which column is your student living in right now?"

Frame the slide: "What the VPA™ adds on top of structure."

Walk each point, one sentence each:

• A standardized administration and scoring procedure, taught in Course 2.

• Criterion-referenced, not norm-referenced.

• The same student produces a comparable profile regardless of who administers it.

• For most school questions the VPA™ is the assessment; attach outside standardized scores only when a payer or team requires them.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Read the scenario aloud, slowly:

Take the client you have had in mind through this session. You are going to leave with a written plan, not a general intention.

Then put these questions to the room:

• Write the functional description in one sentence, in occupational terms.

• Write the referral decision and rationale in one sentence.

• Write the modification you will make Monday and the single observable indicator you will watch.

Give 60 seconds of think time before you take answers. Model answers are in the panel beside this script.

Contrast the two columns: Course 1 — The Five-Level Visual Performance Framework versus Course 2 — The VPA™: Assessment & Clinical Reasoning.

Course 1 — The Five-Level Visual Performance Framework:

• 3.0 contact hours · 0.3 AOTA CEUs · $49

• The framework level by level

• Screening vs. assessment: the OT two-step workflow

• Occupation-based goals and IEP-ready language

Course 2 — The VPA™: Assessment & Clinical Reasoning:

• 4.0 contact hours · 0.4 AOTA CEUs · $79

• Administer the Mini and Full VPA™ to a fidelity standard

• Basal and ceiling rules; the five validity threats

• Findings into goals, justification, and progress monitoring

Ask: "Which column is your student living in right now?"

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Land the "so what": Everything in this course improves your hypotheses. It does not yet give you a score you can report, monitor, or defend.

Explain the mechanism plainly: Structured, performance-based assessment is what converts a good observation into a measurable present level and a progress line.

Then give them the moves — say each one as something they can do Monday:

• Use observation to decide who needs structured assessment.

• Set the setup conditions before you measure anything.

• Plan reassessment on the 9-week cycle so change is visible to the team.

Tell them what success looks like: A confident hypothesis with no measurement behind it — that is where documentation fails.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Reflection prompt: "Write the functional description, the referral decision with rationale, and the Monday modification with the observable indicator you will watch."

Offer the sentence starter: "Functional description:... Referral decision:... because... Monday modification:... I will watch for..."

Think for one minute, write, then take two shares.

Knowledge check: "What does a level-based structure add that a list of observations does not?"

Options:

• A medical diagnosis for the visual finding

• Permission to treat vision without a referral

• A defined order for what to look at first and defensible sequencing language

• A guarantee of reimbursement

Correct answer: option 3. Rationale: Structure orders findings so lower levels are examined before higher ones and so sequencing decisions can be justified in documentation. It does not diagnose, authorize, or guarantee anything.
