Videonystagmography (VNG)

VNG testing is the new standard for testing inner ear functions, replacing Electronystagmography (ENG). We use VNG technology to test inner ear and central motor functions. VNG testing is more accurate, more consistent and more comfortable for our patients. And when patients are relaxed, it’s easier to achieve consistent, accurate test results.

It works by measuring the movements of the eyes directly through infrared cameras to assess vertigo, dizziness and imbalance, and determine the cause of balance disorders.

It’s used to determine if a vestibular (inner ear) disease may be causing a balance or dizziness problem. It’s one of the only tests available today that can decipher between a unilateral (one ear) and bilateral (both ears) vestibular loss. VNG testing is a series of tests designed to document a person’s ability to follow visual objects with their eyes and how well the eyes respond to information from the vestibular system.

This test also addresses the functionality of each ear and if a vestibular deficit may be the cause of a dizziness or balance problem. To monitor the movements of the eyes, infrared goggles are placed around the eyes to record eye movement during testing. VNG is non-invasive and patients only feel a mild discomfort during testing from wearing goggles.

VNG testing is covered by all insurances and usually last about 1.5 hours.

For those with vision problems or other conditions that preclude the vision portion of the VNG testing, we have ENG testing available.
