Videonystagmography (VNG): Eye movements are recorded and analyzed during a series of short tests using high tech video goggles with infra-red cameras
Electronystagmography (ENG): Same as VNG except eye movements are recorded with surface electrodes placed around the eyes
The VNG/ENG helps us to check the vestibular (inner ear balance) system as well as the pathways in the central nervous system responsible for connecting the inner ear, eye movement, and the brain, which are essential for your sense of balance. Your physician may order this test if you are having symptoms of dizziness and/or unsteadiness. The ENG/VNG is comprised of many short tests that are analyzed separately and as a whole providing useful diagnostic information.
Patient instructions and a detailed questionnaire will be mailed to patients prior to their appointment.
