Eye movement testing - Vestibular - Ocular Reflex (VOR) test is used to diagnose the cause of recurrent vertigo (giddiness). VOR is a reflex eye movement that stabilizes images on the retina during head movement. VOR testing should be considered an important part of a group of tests that evaluate vertigo. If a patient is diagnosed with a VOR deficit of one or both ...

 
A saccade is a rapid, conjugate, eye movement that shifts the center of gaze from one part of the visual field to another. Saccades are mainly used for orienting gaze towards an object of interest [2]. Saccades may be horizontal, vertical, or oblique [3]. . Jacques wilson

To test the VOR reliably, it is important to determine that other types of eye movements are normal for two reasons. First, proper interpretation of the VOR responses depends on intact eye movements. Second, abnormalities of eye movements can themselves be useful in localizing neurologic abnormalities. The drops temporarily keep the eyes from changing focus during testing. Eye Focusing, Eye Teaming, and Eye Movement Testing. To see a clear, single image, the eyes must …The purpose of these tests is to detect abnormal eye movement.

If you have nystagmus, your eyes may move up and down, side to side or in a circular motion. Sometimes people are born with it (congenital nystagmus), but you can also develop it later in life (acquired nystagmus). Glasses, contact lenses, medications and surgery are potential treatments.Features of the Developmental Eye Movement Test™ (DEM™): → Provides an objective method of assessing fixational and saccadic activity during reading and non-reading tasks. → Incorporates a sub-test of number calling in a vertical array, allowing for evaluation of oculomotor function with numbers in a horizontal array.These eye movements can be constant or intermittent. They can be horizontal, vertical, oblique, torsional (circular) or combinations of the above. Thus, the study of eye movement can provide important information regarding sight. Eye Movement Testing. The testing is conducted with sophisticated computer technology and video recording equipment. Diagnosis. Treatment. Nystagmus is an eye condition characterized by rapid, jerking eye movements. It does not always cause any noticeable symptoms, but it can be associated with issues such as dizziness and vision problems.
