In this video, you will learn how to perform the gaze test, which measures eye movement generated when maintaining gaze at various angles.
The gaze test measures any eye movement generated when maintaining gaze at various angles. Both central and peripheral lesions can cause extra eye movements when performing this test.
Nystagmus can be generated when the patient is unable to hold their eyes at the desired angle, so the eyes slowly drift back towards the center (in most cases). Corrective movements of the eyes then quickly move them back to the target and nystagmus is recorded.
Some clinicians like to perform gaze testing with both a vision stimulus and with eyes closed. The video shows a patient undergoing a gaze test using visual stimulus. The conditions being tested are left gaze, right gaze, up gaze, down gaze and center gaze.
