TerminologyTracking
- the eye’s ability to move smoothly while following a moving object. *NOT reading*
Fixation
- the
eye’s ability to select an object in the environment and focus it’s gaze on
it; and, inspecting a series of stationary objects (reading).
Acuity
- clearly seeing, inspecting, and identifying objects.
Accommodation
- the eye’s ability to automatically change focus from seeing at one distance to seeing at another.
Ptosis
- drooping eyelid.
Convergence
–the eye’s
ability to turn inward. People with convergence insufficiency have trouble with near tasks such as reading and frequently report eye strain and blurred vision.Slide3
Divergence- the ability to use both eyes as a team and be able to turn the eyes out toward a far object.Diplopia- when two images of the same object are perceived by one or both eyes.(double vision)
Fusion-
the union of images from each eye into a single image
.
Strabismus
- a misalignment of the eyes. The eyes don’t point at the same object together.
Tropia
-always present
Esotropia
- when one or both eyes point inward.
Exotropia
- When one or both eyes point outward.
Phoria
- you have to break fusion
Esophoria
- when one or both eyes point inward
Exophoria
- when one or both eyes point outwardSlide4
Nystagmus- rhythmic oscillations or tremors of the eyes which occur independently of the normal eye movementOcclusion- to block out light. An eye can be completely or partially blocked. Occlusion is often used to promote the use of one eye or both eyes. (ex: patching, squinting)
Suppression
- Stimulated by dissimilar stimuli or when non-corresponding retinal areas are stimulated by similar stimuli or the other is temporarily inhibited or suppressed to prevent confusion.
Binocular Vision
- Ability of both eyes to work together to achieve proper focus, depth perception and range of vision.
Monocular Vision
- Ability of one eye to focus. No depth perception (when changing surfaces
).
Saccades
- Rapid shifts , or little jumps, of the eyes from object to object allowing quick localization of movements in the periphery. The ability of the eye to change fixation from point to point.Slide5

Scope of practice: STAccording to ASHA’s Practice Policy on Scope
of Practice in Speech-Language
Pathology, it is in an SLP’s scope of practice to asses and treat:
Cognition
attention
memory
sequencing
problem solving
executive functioning
Language
literacy (reading, writing, spelling
)Slide9
Scope of practice: OT
AOTA resource manual: Practice Guidelines for Adults With Low Vision
Use remaining vision to participate in desired occupations
Support independent lives
Modify home environment to facilitate safe participation in ADLs
Recommend adaptive devices and assistive technology (optical and non-optical devices)
(
www.aota.org
)
The AOTA recognizes that occupational
therapists help
address visual impairment difficulties
Activities of Daily Living
Evaluate specific daily task
Evaluate environment, and recommend modifications
Recommend adaptive devices and assistive technology (optical and non-optical devices) Slide10
Scope of practice: PTExamining individuals with impairment, functional limitation, and disability or other health-related
conditions.
T
ests
and measures may include the following
:
environmental, home, and work (job/school/play) barriers
gait, locomotion, and balance
neuromotor
development and sensory integration
sensory integrity
work (job/school/play), community, leisure integration or reintegration (including instrumental activities of daily living)
Design, implement, and modify therapeutic interventionsSlide11
FixationThe eye’s ability to select an object in the environment and focus it’s gaze on it;
and inspecting
a series of stationary objects (reading)
.
Assessment
Hold stick with a round bead 16-20 inches away from face
Ask them to look at the bead for five seconds
Observe their ability to focus
If they are unable to complete task:
Have them hold out their own thumb & stare at it for 5 seconds.
I
nput from their own hand may increase the ability to focus
Scoring
WFL: Able to stare at bead for 5 seconds with no apparent eye movement.
Impaired: Unable to stare at bead for 5 seconds and/or has abnormal eye movementSlide12
Fixation TreatmentActivities to encourage holding gaze on a single object
Start with short duration and increase accordingly
Goal:
for eyes to fixate and not dart in any other direction
Achieving attention to a single object
Notes:
“Fixation” requires “attention”
Make it fun –
S
taring contest … 1.2.3 GO!
Use bright colors and familiar objects
Reduce stimulation in environment
Provide postural stabilitySlide13
SaccadesDefinition: Rapid shifts, or little jumps, of the eyes from object to object allowing quick localization of movements in the periphery. The ability of the eye to change fixation from point to point.
Implications:
Reading
Losing their place often
skipping lines
rereading lines
words appearing to jump around the page
letter order confusion.
Poor hand-eye coordination, i.e. ball throwing and catching, self-feeding, writing
Impaired safetySlide14
SaccadesAssessmentHold two sticks, with different colored beads on top (
i.e
red and green), about shoulder width apart.
Ask them to hold their head still and look at one of the colored beads (red).
While they fixate on the red bead, move the other bead (green) up or down. Then ask them to look at the other bead.
Repeat this process until you have assessed their visual pattern.
Look for accuracy, under or over shooting, nystagmus (shaky movements), extended search time, ability or inability to isolate eyes from head movements, and ability or inability to shift into all fields of gazeSlide15
Saccades TreatmentHave them call out letters from two columns on opposite sides of the page
Change the distance between the letters by increasing blank space or adding more columns.

Visual FieldsThe part of space where objects can be seen in the peripheral even though the person is fixating their gaze on one single object ahead of them.
Broken in nasal (medial) and temporal (lateral) hemi fields
Temporal (lateral) hemi field is much largerSlide21
Central Field Also called peripheral field
Highly
detailed area of the
retina
5° around
fixation point
Responsible for
Detailed
vision
Reading
Recognizing faces
Detecting colors
Highly sensitive to light
Low sensitivity to motionSlide22
Peripheral FieldThe total area around central visionBecomes a secondary visual process to central vision.
This process is then used as general spatial orientation system and is integrated into the sensory-motor feedback loop
Characterized by:
High sensitivity to movement
Low sensitivity to light and detailSlide23
Visual FieldWNL: 50°-60° upward
70°-75° downward

nasally/medial
90°-110°
temporally/laterallySlide24
Field Loss vs. Visual NeglectPhysical loss of visual field to one
side
Decreased Perceptual field
Also Called:
Homonymous
hemianopsia
Attention impairment where pt. is unable to attend to one side of their
body
Also Called
Hemi-spatial neglect
Hemiagnosia
Hemi-neglect
Unilateral neglect
Hemi-inattention
Unilateral visual inattention
Neglect
syndrome
Visual Field Loss
Visual Neglect
Pt. with both have a worse prognosis for recovery, due to difficulty learning to compensateSlide25
How Lesions Effect the Visual Field
Level 1 lesion- Can lose sight fully in one eye
Level 2-4 lesions – Cortical blindness
Treatment: Compensate- NOT regain functionSlide26
Visual Field Loss TreatmentDetermine available range
Use of target localization tasks to train
them
to make large eye movements and systematic scanning strategies
Incorporate efficient
ROM/head
turning training with PT and OT treatment
Use of visual/auditory anchors
Colored electric tape on table edges, doorways (red for left, green for right)
Placing objects that provide auditory feedback on the affected side (alarm
clock,
phone)
Appropriate challenge
only (Safety first)
Compensate first to reduce stress
Grade
activities up as skill increasesSlide27
Visual Field Loss or CutAssessment
Have pt. cover one eye and fixate on an object in front of them
Stand behind
them
with a long wand
Ask them to tell you when they see something in their field of view and slowly
bring the wand into
their
view from behind them at various angles, including:
top, bottom, horizontal, diagonal approach to test each quadrant.
Present target multiple times to confirm deficit.
Be cautious not to let
them
see your arm move because they may guestimate when they will see the wand based on
your body movement
Repeat with other eye and both eyes together
Scoring
WFL: They see wand within appropriate degree measures
Impairment:
They don’t see the wand in their peripheral field within the specified degrees. Slide28
Importance of assessing patients with neurological involvement for visual neglectVisual-spatial neglect has been reported in:
up to 82% in right hemisphere strokes and
65% of left hemisphere strokes.
Yet, by using the cross-out task only as an assessment tool, neglect was found in:
only 25% of right hemisphere strokes and
2% of left hemisphere strokes. Slide29

How long will it take?
What percentage will you get correct?
Do you understand the activity?
Will you need to ask more questions?
What might effect your performance
Have client re-grade themselves after they’ve completed the taskSlide35
Visual Neglect Treatment Ideas
Red Velcro Strip
Red guides on side of page
Tracking printed words from book on tape
Vibrating pager -
Set to vibrate on effected side every 12 seconds
Place items on effected side and have patient look for them and retrieve them.
Marking each box of a grid with a X
Money counting
Checker Board
Have patients manipulate tokens vertically and horizontally across boardSlide36
Visual Neglect TreatmentUse of stimuli known to activate the affected side of the brain
Left brain: use letters and numbers
Right brain: use shapes and blocks
Environmental modifications at home
Incorporate motor movements of the affected side
PT: clenching and unclenching affected hand during gait retraining
OT: Use the affected arm as a perceptual anchor for full visual field scanning during performance of ADLsSlide37
VergenceEye teaming – or using both eyes together efficiently
Eye teaming is a reflex related to accommodation
Accommodation
- eye’s ability to automatically change focus from seeing at one distance to seeing at another
.
Convergence – with accommodation
Divergence – relaxation of accommodation
This reflex allows object fuse into single and clear, both at a distance and near.
Impairment of
vergence
leads to:
Dioplia
, or double
vision
Confusion
Phorias
- misalignment of eyes
Strabismus – noticeable eye turns in or out
Suppression- the brain ignores all or part of an image in order to avoid
dioplia
Amblyopia – brain disregards most information coming from one or both eyesSlide38
Convergence The eye’s
ability to turn inward. People with convergence insufficiency have trouble with near tasks such as reading and frequently report eye strain and blurred vision
.
Assessment
Hold a colorful target approximately 16 inches away from the
pt’s
nose
Instruct the
pt
to keep there eyes on the target as it moves closer to them and to tell you when they see double.
Slowly move the target towards the
pt’s
face.
Observe the
pt’s
eyes to see when one of the deviates from the target, signifying the point where the
pt
should see double.
Scoring
WNL: deviation when target is 3-4 inches from
pt’s
nose
WFL: deviation when target is 4-6 inches from
pt’s
nose
Impaired: deviation when target is more than 6 inches from
pt’s
nose. Slide39
Convergence TreatmentBrock String
A white string approx. 10-15 ft. long with three beads of various colors
Tie one end of string to a stationary objects such as a door knob of cabinet
Have pt. hold the other end at the tip of their nose
Method 2
Bead positions
six
inches, 18 inches and four feet from the loose
end
Push gaze to focus on first bead. Strings should cross
Hold for 10 seconds
Repeat on 2
nd
and 3
rd
beads
Repeat entire process 5 times
Method 2
Place 1
st
bead at the place of double vision
Place 2
nd
bead at the place of single vision
Have patient focus on each
Method 3
See treatment hand outsSlide40
Convergence TasksJump Convergence
Give patient two
different color pencils and
position them approx. 5
feet in front of a
blank wall
.
Have pt. hold
one pencil in
left
hand with
their arm
fully extended in front of
the
face
.
Hold
the other pencil
right hand and position midway
between
pt.’s
nose and the other pencil.
Look
at the pencil that is further away.
Pt . should
see the closer one in double.
Look
at the closer pencil.
Pt. should
see the further pencil in double
Have patient bring both pencils closer to their face and look
at each of them again. Repeat this exercise until patient is unable to avoid double vision when looking directly at one of the pencils.Dotted CardDraw a straight line in the across the middle a sheet of paperDraw 5 or more dots equally spaced along the line with different color inksPosition the paper
in front of
pt’s
face so
that the line extends outward
so they can see
the dots on the line.
Have pt. look
at the furthest dot for 10 seconds.
The
rest of the dots should form a blurry
letter
A.
Move
to the next closest
dot, while maintaining
a single image of the furthest dot.
Focus on the second farthest dot for 10.
Continue
moving closer, looking at each dot for
10
seconds until
the
pt
can no longer maintain a single image of the dot
they are focusing on.
The
blurry A shape should gradually transform into a blurry V-like shape as
the pt.
focus on points that are closer to
their
nose
.Slide41
DivergenceAssessment
Position
pt
in front of your left side, where they can look over your shoulder.
H
ave pt. look at a pencil topper approx. 6 inches in front of them.
Next have
pt
look at an object behind you.
Observe how the
pts
eyes turn in and out between convergence and divergence.
Repeat with
pt
positioned on right side.Slide42

Ocular AlignmentAlignment is crucial to coordination/function of both eyes. If unaligned, pt. may experience double vision, vertigo, etc.
Assessment
Sit directly in front of pt. at midline. Instruct pt. to look into your eyes.
Shine pen light between pt.’s eyes from 16-20 inches away
Observe if the reflections in pt.’s eyes are in approximately the same positions.
Scoring
WFL: light reflects in the same position in each eye (typically in the center of each pupil)
Impaired: light reflects in different position in each eye (strabismus of one or both eyes)Slide44
Ocular Range of MotionAssessmentHold a stick with a bead on top approximately 16-20 inches from
pt’s
face.
Instruct
pt’s
to keep their eyes on the bead everywhere it goes while keeping their head still
Move bead through the horizontal, vertical, and diagonal planes, holding 5 seconds between each movement.
*slow and steady*
Observe the
pt’s
eye movements to see if they complete
the full range or if
their eyes
drift instead
Repeat with each eye individually and together
Scoring
WFL: Able to follow target through full range
Impaired: if pt. is unable to follow beadSlide45
Smooth Pursuits
Movements that allow the image to stay in focus on the retina while tracking a moving target.
Quality of ROM
Assessed in conjunction with ROM
During ROM assessment:
Observe
the
pt’s
eye
movements. Do they jerk
, shake, or have
erratic/ballistic
movements.
Scoring
WFL: Movements are smooth while tracking bead
Impaired: Eyes jerk, have
nystagmus
(shaky movements) or move erratically. Slide46
Treatment for Alignment, ROM and Smooth Pursuits
Medication
Surgical
SLP treatments
Acquired alignment impairments are different from congenital deficits.
If problem is due to muscle imbalance,
begin eye exercises,
s
uch as ROM exercises
If problem is due to double vision
occlude the affected eye **
Begin fusion exercises
Place an object where the
pt
can see it without double vision, then slowly move the object into the
pt’s
double vision range.
Adaptation of lifestyleSlide47
Treatment for Alignment, ROM and Smooth Pursuits Therapist’s

Visual Spatial SkillsSkills used to understand directional concepts in spaceSigns and Symptoms
Difficulty distinguishing left and right
Lack of coordination and balance
Reverses letters or numbers when writing or copying
Does not cross midline when doing tasks
Gets lost following directionsSlide49
Visual OrientationLaterality:
Awareness
of
the two
body sides and knowing they are different.
Directionality
A
wareness of up, down, ahead, behind, and any combination there after
Consists
of two orientations:
Internal Self
Awareness
i.e
. left and right
hands
Projection
into the external visual space
i.e. Understanding the difference between the left and right side of the room.
** If
a
pt’s
internal self awareness is impaired, their concept of external visual space will also be impaired
. **Slide50
Visual Orientation AssessmentAsses
pt’s
awareness of left, right,
up, down, ahead,
behind with both auditory and visual tasks.
Reading of minimal pairs with graphemes that have similar orthographic representations.
i.e. ben, den, pen,
qen
If visual orientation is impaired letter decoding will be impaired.Slide51
Visual Orientation Tx
Incorporate:
sequencing,
auditory comprehension
r
eading comprehension
upper
extremity movement with laterality
Encourage crossing of midline
Examples:
Catch and throw a ball with the left and right
hands
Look left – look right
Place all the red items on your left and yellow ones on the right
Go down the hall and turn right and tell me what picture is on the leftSlide52
Bilateral IntegrationAbility to use both sides of the body separately and/or simultaneously

/app/vat/Slide55
Visual Form Recognition/ Discrimination and ConstancyAbility to discriminate differences in form including size, shape, color and orientation
i.e
CAT= Cat = cat; (Which one is lower case?)
Which is more water? The water in the glass or the water in the bowl?
Of these 2, which is larger?
Treatment examples:
Tetris
Recognition of word similarities with variation of orthographic forms
i.e. Horse = HORSE = horseSlide56
Visual ClosureThe ability to recognize visual stimuli which cues the
pt
to determine what an object or word should look like.
i.e. Being able to complete a word or picture that is partially obstructed, such as words on a road sign or pictures on a warning sign.
Treatment examples:
Trail making with dots, letter, numbers, or words
Choose the missing piece given F:3Slide57
Visual Spatial MemoryAbility to recall the spatial location of an object or stimuli. The ability to be able to recall, identify, or reproduce a design or dominant feature of an object. Example: Being able to picture a lost object; seeing a printed word and developing a mental picture to the corresponding object.
Treatment examples:
Memory
Card
Game,
Reduplication of bicolored block designs without a visual referenceSlide58
Visual Sequential MemoryAbility to view and recall a sequence of numbers, letters, objects in the order they were presented.
i.e
recalling a phone number, how to spell a medication name, or dosage instructions.
Treatment example:
Electronic
S
imon SaysSlide59
Visualization Ability to mentally manipulate a previously viewed stimuli. i.e. deciding if a flattened box will fit an object you want to ship, if a walker will fit through a doorway, or if there is enough room to safely stand up between the chair and a supportive surface (table, grab bar, therapist)
Treatment examples:
T
angram puzzles
Pegboard
Functional mobility around hospital, office, home with prompts to check visualization accuracySlide60
Visual Midline Shift Syndrome“mismatch between spatial information received through ambient visual process and kinesthetic, proprioceptive, and vestibular system”
Ambient visual process
From the peripheral portion of the retina to the midbrain (sensory-motor loop) to occipital cortex (feed-forward)
Responsible for body awareness in space
Results
in a tilt in the horizontal space causing balance
deficits
Visual MidlineSlide61
VMSS AssessmentPatient position: sitting or standing
Therapist:
Move an object horizontally in front of patient’s facial plane
Ask patient to tell you when it is directly in front of their nose
Move an object vertically in front of patient’s facial plane
Ask patient to tell you when it is directly at eye level
Result:
Perception to the left means visual midline has shifted to that direction resulting in right neglect
Perception of eye level when target is above eye level means there was a posterior shift resulting in backward lean
* Shift is typically away from neurologically affected sideSlide62
