The optokinetic response is a combination of a slow-phase and fast-phase eye movements. It is seen when an individual tracks (pursuit movement) a moving object with their eyes, which then moves out of the field of vision at which point their eye moves back to the position it was in (saccade movement) when it first saw the object. 

The App is an easy to use replacement for a bulky optokinetic drum or a fraying cloth tape to elicit optokinetic nystagmus, OPK or OKN, for evaluation of neurological, otological, and opthalmological disorders. Simply place the app screen with a moving pattern in front of a patient’s eye to elicit the response. The stripe pattern, width, and speed are easily adjustable.

The application helps identify optokinetic nystagmus. It is my hope that it can be helpful to assess normal eye movements.
