Why Visual Performance Matters: Foundations for Occupational Therapy Practice

Housekeeping while people arrive.

Materials to have ready:

• Participation & Reflection Guide (printed or on screen)

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.

Explain how the session runs.

Schedule:

• Six modules, 3.0 contact hours total

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

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.

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.

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.

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).

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.

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

Oculomotor and acuity:

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

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.

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:

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:

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.

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.

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.

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

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

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

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

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.

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:

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.

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:

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.

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.

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.

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

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)

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.

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

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

What it is:

• Congenital under-development of the optic nerve

Contrast the two columns: Strabismus versus Amblyopia.

Strabismus:

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

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

Walk each point, one sentence each:

• Esotropia — eye turns inward.

Contrast the two columns: Ocular albinism versus Nystagmus.

Ocular albinism:

• Hereditary condition; excess light enters through an unpigmented iris

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

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

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:

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

Refer promptly:

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

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:

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.

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

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

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.

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

What is reported:

• Reduced eye contact or difficulty sustaining visual focus

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

What is reported:

• Difficulty sustaining focus on visual tasks; easily distracted

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

What is reported:

• Letter or number reversals; misaligned text or math columns

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

Walk each point, one sentence each:

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

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).

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:

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.

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:

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.

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.

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.

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

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.

Contrast the two columns: Environment versus The page.

Environment:

• Preferential seating closer to the front / instructional materials

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.

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

Real-world contrast values:

• Exit sign: ~80% contrast

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.

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

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).

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:

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.

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:

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.

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.

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

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

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.

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.

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

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.

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:

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

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:

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

Talk through this close step in Module 6.
