Oculomotor Lecture
Oculomotor Lecture
Presentation lecture from:Mary Warren, Uni. of Alabama at Birmingham
Evaluation Purpose
* Determine if an oculomotor impairment exists and interferes with occupational performance
o Not to diagnose the impairment
* Evaluation should be a simple screening using a “look and listen” approach
o Look at the deviations in oculomotor control
o Listen to patient complaints regarding occupational performance
Begin Evaluation by Listening
* Obtain visual history
o Congenital childhood strabismus
+ Did pt have eye surgery, patching as a child?
+ Did anyone ever tell the patient h/she had a lazy eye?
o If patient had a head injury
+ Was there any trauma to the eye or orbit?
* What are the patient’s functional complaints?
o Print blurs when reading
o Unable to keep objects in focus
o Balance difficulty
o Past pointing/reaching
o Eye fatigue/eye pain/headache with sustained focus
o Difficulty maintaining concentration on activities requiring sustained focus
+ Reading or computer work
o Nausea/blurring vision with head movement
o Blurring of vision when changing focal distances
Assessment of Diplopia
* Subjective complaints of diplopia
o Lateral or vertical splitting of images
o Present at near distances or far distances
o Present intermittently or constantly
o Direction of affected gaze
+ Primary gaze
+ Right or left gaze
+ All gaze directions
o Minimize or exacerbated by head position
o Accompanied by blurring vision when head movement
* Objective observations
o Disappears when one eye is closed
+ Indicates oculomotor impairment
o Remains with closing of one eye
+ Indicates some other cause such as retinal injury
o Area of fusion
+ All persons have some area where they can see a single image known as the fusion zone
+ Distance from face
+ Ability to maintain fusion within the zone
o Neck range of motion
+ Horizontal and vertical
