VIP Assessment Continued And VIP Therapy Flashcards
Comitancy testing
Red lens test
Subjective test that involves dissociating the two eyes by placing a red lens in front of one eye (one sees red and the other see the white light). The patient is asked to describe the relative position of the red light and white light in all 9 directions of gaze

Comitancy testing
Red lens test
Hess Lancaster
Most selective test for comitancy
Hess Lancaster
Materials for hess Lancaster
Grid, RG glasses, and RG wands
Purpose of hess Lancaster measure the relative postuions for all 9 directions of gaze
Red sees red and green sees green

Differentiates an anatomical muscle restriction from a cranial nerve palsy
Forced duction
How to do forced duction
- the patient looks in the direction of restriction-forceps are used to grasp the conjunctiva and move the eye in that direction
- positive: does not move in the direction=anatomical restriction
- negative: eye can be moved=muscle palsy
Subjective angle=0, objective angle-angle of anomaly
Harmonious ARC
- the patient will not have symptoms of diplopia or confusion
- this is the most common type of ARC
Most common type of ARC
Harmonious
Most common type of ARC
Harmonious
Unharmonous ARC
Angle of anomaly < objective angle; subjective angle does not equal objective or 0 (somewhere in between)
-the patient will have diplopia and confusion because there is not perfect correspondence (may not see this clinically)
Paradoxical ARC
- type 1: subjective angle > objective angle
- type 2: subjective angle is in the opposite direction of the objective angle. Examples: ET has temporal ARC rather than the expected nasal
- both types will have diplopia and confusion worse than if the patient had NRC
Covariance
Type of correspondence shifts depending on which eye is fixating (often show harmonious ARC when the normal eye is fixating while NRC used when the strab eye is fixating)
What is the most commonly used cognitive test for psychoeducational evaluations
Weschesker intelligence scale for children IV
What is the average for scaled score, standard score, and Z score for IQ
10, 100, 0
What is your sequence for VIP testing
Comprehensive-BV-VIP
Low PRA
Accommodative insufficiency
treatment for VIP problems
Treat refractive error and visual efficacy deficits before attempting VIP therapy. Always check to see if they have a vertical heterophoria
A lot of previous therapy techniques may be modified and used with VIP therapy
Often involves co-managment: some therapy is better suited for other specialties
Therapy considerations
Age and developmental status Motivation Cooperations Cognitive development and style Auditory abilities
Treatment of visual spatial dysfunction
- includes bilateral integration, laterality, and directionality
- goal: develop the patient’s internal and external spatial concepts that help organize the environment
Bilateral integration
Abiltiy to plan motor actions useing the right and left sides of the body
Laterality
Ability to be internally aware and to identify right and left on oneself
Overall goal: develop the patient’s internal awareness of how the right side if different from the left side into concepts that the patient expresses orally
Directionality
-ability to use directional concepts to organize external space
Recommended that treatment proceed in the these steps for visual-analysis dysfunction
- Visual discrimination
- Figure ground
- Visual closure
- Visual memory
- Visualization
Abiltiy to be aware of distinctive features including size, shape, color, and orientation
Visual discomrination
Abiltiy to attend to a specific feature or form while maintaining awareness of the form with background information
Figure ground
Ability to determine the final precept without all details being presented
Visual closure
Ability to recognize and recall visually presented information
Visual memory
Ability to recall visually presented materials and to manipulate these images mentally
Visualization
Visual motor dysfunction
Abiltiy to integrate vision with the motor system
4 components of visual motor
General eye hand coordination
Efficiency visual motor skills
Rapid fine motor control
Ability to plan motor skills involving complex spatial patterns
