VT Theory and Programming: Oculomotor Flashcards
Basic overall sequence of Vision Therapy (7 phases)
What phases do most of your VT program fall in?
Phase 1: Optimal Lens prescription
Phase 2: Gross motor
Phase 3: Monocular
Phase 4: Bi-ocular
Phase 5: Binocular
Phase 6: Binocular with loading
Phase 7: VIP
Most of VT program falls in phase 3-5. Monocular, Bi-ocular, binocular.
What are the Phase 3 activities?
Monocular accommodative
Monocular Oculomotor
What are the phase 4 activities?
Bi-ocular / Anti-suppression accommodative activities
Bi-ocular / Anti-suppression oculomotor activities
Anti-suppression / Basic fusion (1st degree fusion)
What are the phase 5 activities?
Binocular accommodation activities
Binocular oculomotor activities
Fusion therapy activities
What are the phase 5 activities?
Binocular accommodation activities
Binocular oculomotor activities
Fusion therapy activities
Where in VT do you start with a patient? Where do you move to?
Start where a patient can succeed then move to where the patient struggles
What is the oculomotor hierarchy?
Gross motor –> fine motor –> oculomotor
What is the hierarchy of skills for visual function? (4)
1) Orientation of the body in space
2) Oculomotor skills
3) Binocularity and accommodation
4) Perceptual function
When all 4 skills of visual function work together, what does this give us?
Good vision
The primary purpose of the ____________ is the derivation of meaning and the direction of action
visual system
What does developmental Ocular motor dysfunction have to do with?
Poor body coordination, could have poor laterality and directionality
What would be shown with testing on a patient who has developmental OMD?
Failing the “ability” on maples testing
Excessive body movement
Excessive head movement
What would therapy for developmental OMD focus on?
Work on gross motor first
Improve rhythm
What are 6 gross motor exercises you can do for patients with developmental OMD?
Army crawl
Balance board
Walking rail
Motor equivalent/ chalkboard circles
Handball
Bunting
Laterality vs directionality (for developmental OMD)
Laterality: on self
Directionality: on other things
True or false:
Oculomotor therapy is done in all VT programs?
True
What does Functional OMD manifest as?
poor eye tracking skills
If someone has a functional OMD, would they have a normal or abnormal “ability” on Maples Test?
Normal ability on maples test
What therapy would you use for Functional OMD?
Begin working fixation
Move to saccades, then pursuits
Monocular, bi-ocular, binocular
Large saccades –> small saccades
Small pursuits –> large pursuits
What can patients use when saccades are smaller than 30 degrees?
Eyes only
What can patients use when saccades are larger than 30 degrees?
head/torso/body movements
Basic order of functional OMD therapy
Work on accuracy first
Eliminate head and body movement
Then increase appetite and length (stamina)
Higher level accuracy of fine movements
What age should you have no body movement by?
5.5-6.5 years old
