Vestibular/Balance Assessment

Hearing aidVideonystagmography (VNG) and Caloric Testing

VNG tests are designed to test your balance function and is requested primarily by Neurologists and Ear, Nose and Throat specialists.

VNG allows us to evaluate vestibular and central functions by monitoring eye movements. During VNG, the patient wears goggles that are designed to record eye movements. Eye movement analysis can give important information about the workings of an individual’s balance system.

A common part of VNG is called caloric testing. This test involves slight changes in the temperature of a patient’s ear canal, one ear at a time. The change in temperature can elicit eye movements by reflex. Some patients are nervous about the dizziness that can occur during this test but this is brief and bearable.

Please do not take any dizzy medication 48 hours prior to testing
Please remove all eye makeup before the test.
Please do not consume alcohol in the 24 hours prior to testing.
