In this video, you will learn how to perform the optokinetic nystagmus test, which can help to determine the presence of central lesions.
The optokinetic test uses a similar system to the smooth pursuit system and in fact the smooth pursuit system is implicated in this test. The difference is that the stimulus in optokinetic testing should be "full field" meaning that it occupies all of the patient's field of vision.
It can be used a part of a test battery approach to determining the presence of central lesions.
This video demonstrates a patient undergoing optokinetic testing.
