Vision in OT Practice

Transition: "A Structured, Level-Based Visual Performance Framework for Clinical Reasoning."

Open here. "The Five-Level Visual Performance Framework." A developmental hierarchy that organizes observation, assessment, and intervention.

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

Ask the poll: "Which framework levels do your current goals most often target?"

Options:

• Level 1 — acuity and sensory access

• Level 2 — visual efficiency

• Level 3 — visual processing

• Level 4 — visual-motor integration

• Level 5 — functional integration

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

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.

Frame the slide: "Visual development milestones OTs should know."

Walk each point, one sentence each:

• Basic eye movement control (fixation, following) is commonly described as established by 2–3 months of age.

• Coordinated eye movement control is commonly described as expected by about 2 years.

• Complex visual-motor and visual-perceptual control is commonly described as continuing to mature until roughly 9 years — the age by which most school-readiness visual skills are expected to be reliable.

• Visual acuity is commonly described as progressing rapidly in infancy and approaching adult levels well before school entry, while efficiency and processing skills mature much later.

• Eye dominance (sighting preference) is commonly described as emerging and stabilizing in stages — around ages 4, 7, and 12 — with instability past those windows worth noting, not diagnosing.

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: Ventral / parvocellular ("what" pathway) versus Dorsal / magnocellular ("where" pathway).

Ventral / parvocellular ("what" pathway):

• Carries fine detail, color, and form for object and letter identification

• Classroom sign: confuses similar letters/numbers (b/d, 6/9)

• Classroom sign: struggles to identify an object embedded in a busy picture

• Classroom sign: slow, effortful sight-word recognition despite adequate acuity

Dorsal / magnocellular ("where" pathway):

• Carries motion, spatial location, and visual guidance of movement

• Classroom sign: misjudges distance when reaching, stepping, or catching

• Classroom sign: loses place moving between lines or from board to desk

• Classroom sign: difficulty with maps, block designs, or spatial math layout

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

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.

Frame the slide: "How the Five-Level Framework was built."

Walk each point, one sentence each:

• OTPF-4 names visual functions as client factors — the framework simply organizes them by the order they have to be stable in.

• The developmental sequence of visual skill sets the floor order: sensory access, then efficiency, then processing, then visual-motor control, then occupation.

• Dual-stream neuroscience explains why two students fail the same worksheet for opposite reasons, so each level carries its own probe.

• School caseload data shaped the level definitions around what can actually be measured in a 30-minute session and written into an IEP.

• The clinical rule holds at every floor: an unstable higher level is never trusted until the levels beneath it are confirmed stable.

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: "One example per level."

Say the caption in your own words: What you see, the probe that confirms it, and the OT move that follows — for all five levels.

Run the five levels bottom-up.

Name each level, then say which one you assess first and why.

Contrast the two columns: Functional signs versus OT direction — adapt and refer.

Functional signs:

• Print held very close or pushed away; head tilt

• Fails photocopied/low-contrast packets, fine on crisp ones

• Performance drops in window glare or late in the day

• Misses curb edges, thresholds, food on the plate

OT direction — adapt and refer:

• Raise contrast; enlarge by task, not globally

• Kill glare; control clutter and spacing

• Set working distance where performance is best

• Write the eye-exam referral in parallel, not after

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

Talk over the visual: "Access, before and after."

Say the caption in your own words: The same worksheet at photocopy contrast and at full contrast with larger print — the gain came from the page, not the student.

Contrast the two columns: Functional signs versus OT direction — remediate + support.

Functional signs:

• Loses place, re-reads, finger-tracks past expected age

• Accurate early, degrades by minute 8–10

• Blur, doubling, headache, "words move" after near work

• Reads as inattention in the last block of the day

OT direction — remediate + support:

• Graded scanning and cancellation on real class text

• Near–far transitions tied to board-to-desk copying

• Fade support: finger → card → typoscope → none

• Keep a compensatory tool while stamina is built

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

Talk over the visual: "Line loss and the stamina curve."

Say the caption in your own words: Place-keeping errors across a 2-minute passage, and accuracy decaying past minute 8 — an efficiency signature, not inattention.

Talk over the visual: "Oculomotor control — the movement systems."

Say the caption in your own words: Fixation, smooth pursuits, and saccades carry reading and copying. When they fatigue, accuracy decays on a predictable curve — the classroom signs and the OT directions, side by side.

Contrast the two columns: Functional signs versus OT direction — load, then strategy.

Functional signs:

• Cannot find the item on a busy page or crowded hook rack

• b/d/p/q confusion past the developmental window

• Many glances per copied word; model does not hold

• Reverses place value; struggles with maps and diagrams

OT direction — load, then strategy:

• Cut visual load: fewer items, boxed work, stable layout

• Teach a narratable search pattern and self-cue

• Chunk the model; preview the page for landmarks

• Outcome = independent strategy, not worksheet score

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

Talk over the visual: "Visual load on the page."

Say the caption in your own words: Same target item on a crowded page and a de-loaded page with a taught search pattern: 41 seconds with prompts vs. 7 seconds without.

Talk over the visual: "Perception — and what it looks like in handwriting."

Say the caption in your own words: Discrimination, visual memory, spatial relations, and figure-ground — and how each one surfaces on the page as placement, orientation, sizing, and spacing errors.

Contrast the two columns: Functional signs versus OT direction — isolate, then treat.

Functional signs:

• Legible in isolation, degrades under speed or volume

• Drifting baselines, sizing, spacing, margin overruns

• Copying, diagrams, and cutting on a line are hard

• Keyboarding accuracy and fastener tasks lag

OT direction — isolate, then treat:

• Compare trace vs. copy vs. dictation before planning

• Clean dictation + poor copy = treat upstream levels

• Shrinking model, part-to-whole, spatial scaffolds

• Pair with access: reduced copy volume, notes, tech

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

Talk over the visual: "Trace vs. copy vs. dictation."

Say the caption in your own words: Three writing samples of the same sentence. Clean dictation with a poor copy points upstream — treat Levels 1–3 before drilling the hand.

Talk over the visual: "When the eyes and hand stop agreeing."

Say the caption in your own words: The trace–copy–dictation comparison at a glance, with the functional signs and the clinical rule that keeps you from drilling the hand for an eye problem.

Contrast the two columns: Functional signs versus OT direction — measure the occupation.

Functional signs:

• Reading rate and endurance below expectation

• Written output far below spoken capability

• Incomplete work, avoidance, late-period fatigue

• Multi-step visual tasks fail in class and community

OT direction — measure the occupation:

• Goal = sustained minutes, accuracy, output, independence

• Intervention sits on whichever floor is unstable

• Document the chain: occupation → level → dose → probe

• Re-probe with the identical baseline task

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

Talk over the visual: "Where the goal line sits."

Say the caption in your own words: Baseline and 9-week re-probe on the occupations themselves: sustained reading minutes, sentences copied, written output, and work completion.

Frame the slide: "Two rules for choosing where to start."

Walk each point, one sentence each:

• Bottom-up to stabilize: adapt or fix the lowest unstable floor first.

• Top-down for meaning: pick the occupation, then find the floor holding it up.

• Run both threads at once — remediation on the floor, compensation on the occupation.

• If you cannot tie the session to the student's day, you picked the wrong level.

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: "The Active OT Remediation Pathway."

Say the caption in your own words: Medical clearance is the floor; the five levels climb from Visual Access through Functional Integration. Remediate the unstable floor on one side, compensate on the occupation on the other.

Frame the slide: "The same four-part shape, every level."

Walk each point, one sentence each:

• 1 — Baseline probe: re-measure the same task before you treat.

• 2 — 6–10 min graded work on the unstable floor.

• 3 — 3–5 min of that skill inside the student's real classroom material.

• 4 — One-sentence hand-off to the teacher naming the support to keep.

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

Contrast the two columns: Level 1 — Access versus Level 2 — Efficiency.

Level 1 — Access:

• Contrast and print-size trials, not drills

• Record the best condition; paste it into accommodations

• Glare control and setup taught as self-advocacy

• Eye-exam referral sent the same day

Level 2 — Efficiency:

• Fixation hold → saccadic accuracy → pursuit path

• Near–far transitions tied to board-to-desk copying

• Timed re-probe of the passage you opened with

• Fade support in writing: finger → card → typoscope → none

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

Contrast the two columns: Levels 3–4 versus Level 5.

Levels 3–4:

• Stress one processing skill inside a real page

• Outcome = the strategy the student narrates unprompted

• L4: trace vs. copy vs. dictate before you plan

• Pair every remedial block with an access change

Level 5:

• End every session inside the occupation itself

• Sustained reading minutes, full copy task, timed writing

• This probe is the goal line — nothing else belongs there

• Document occupation → level → dose → probe

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

Contrast the two columns: Levels 1–2 versus Levels 3–5.

Levels 1–2:

• L1: Fast Screener acuity/contrast; VPA ladders at 60 cm and 40 cm; printable cards in the Worksheet Print Hub

• L2: Follow the Ball, Dynamic Pursuit, Tracking Patterns, Arrow Zigzag, Saccade Sweep, Letter Hunt, Jumping Words, Convergence Zoom, Z-Pattern Scan Grid

• L2: Red/Green anaglyph screening + intervention packets

Levels 3–5:

• L3: Hidden Treasure Hunt, Figure Ground, Form Constancy Contrast Challenge, Memory Grid, Visual Closure — each with a matched worksheet

• L4: Visual Motor Skills, grid/spatial-planning sheets, curriculum-neutral handwriting-readiness packets

• L5: grade-banded reading and writing probes, Treatment Templates (9-week LTG/STO), generated clinical report

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?"

Describe what belongs here: Your own framework graphic, if you want it in place of the built-in ladder slide..

Describe what belongs here: Interactive activity or worksheet that demonstrates work at one specific level..

Land the "so what": Most "visual processing" referrals resolve one or two levels lower — the signal was not getting in, or the eyes were not staying on the work long enough to process anything.

Explain the mechanism plainly: The five levels are ordered by dependency: acuity and sensory input, efficiency, processing, visual-motor integration, functional integration.

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

• Before you buy a processing program, confirm Level 1 and Level 2 are accounted for.

• State the level you are targeting in the goal so the team can see the reasoning.

• Re-check the lower level when progress stalls instead of adding more of the same activity.

Tell them what success looks like: Fast gains once the lower level is addressed — that is confirmation you had the level wrong, not luck.

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

Two-minute case. Read it aloud:

A Grade 3 student reverses letters, loses his place, and rubs his eyes after five minutes of reading. The teacher asks for "visual perceptual therapy."

Put the question to them: "Which level do you investigate first, and what does that change on Monday?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Level 2 (visual efficiency) comes first: place-losing plus eye rubbing after a short latency points to fixation and near endurance, not discrimination. Check habitual correction is worn (Level 1), then trial a spaced page and a line marker before any processing program.

Close with the rule: Symptoms that appear with time on task are efficiency findings until proven otherwise.

Reflection prompt: "Take one student. Which level is the lowest one showing a breakdown, and what observable behavior tells you that?"

Cues:

• Start at the bottom of the ladder, not at the complaint.

Offer the sentence starter: "The lowest level showing a breakdown is... The behavior that tells me is..."

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

Knowledge check: "A student copies inaccurately from the board and loses his place mid-line. Where should intervention planning begin?"

Options:

• Level 4, because the written output is inaccurate

• Level 5, because the classroom task is the problem

• The lowest level showing a breakdown, verified before working upward

• Whichever level the teacher reports first

Correct answer: option 3. Rationale: The framework is a hierarchy. Treating an upper level while a lower one is unstable produces gains that do not carry into occupation.
