mVEP Testing
Five small sensors are placed on the head which record the brain's response to moving stripes that are displayed on a computer screen. Each eye is tested while the other eye is patched. Each recording trial lasts about 10 seconds, and several trials are done for each eye.
Stereoacuity Testing
Subjects will have their 3D perception measured using standard clinical stereo tests (Randot, Lang, Titmus).
Optokinetic nystagmus testing
Subjects will be asked to view a screen with vertical stripes moving in both leftward and rightward directions while their eye movements are recorded using a remote video-based eye tracker.
Motion detection testing
Subjects will view a computer screen that has two panels of dots on them. The subject will be required to pick which panel has a section of dots that are moving in a specific direction (ie. nasalward/temporalward).
Motion discrimination testing
Subjects will view a computer screen that has two panels of randomly moving dots on them. The subject will be required to pick which panel has a section of dots that are moving in a specific direction (ie. nasalward/temporalward).
