VNG

AuDSLP offers Videonystagmography (VNG) technologies to test inner ear and central motor functions. We perform VNG tests to help determine the causes of your dizziness or balance problems.

Overview:

VNG testing is accurate, consistent and comfortable for dizziness patients. In fact, VNG testing is now considered the standard for testing inner-ear function because VNG measures the movements of the eyes directly through infrared cameras instead of measuring the mastoid muscles around the eyes with electrodes like previous ENG tests.

Our goal in administering the VNG test is to determine if inner-ear disease is causing a balance or dizziness problem. It’s one of few tests that can identify and recognize the differences between vestibular loss in one or both ears. This test also addresses the functionality of each ear and if a vestibular deficit may be the cause of a dizziness or balance problem.

VNG tests document a person’s ability to follow visual objects with their eyes and how well the eyes respond to information from the vestibular system. To monitor the movements of the eyes, infrared goggles are placed around the eyes to record eye movements. VNG testing is non-invasive, and only minor discomfort is felt by the patients during testing as a result of wearing goggles.
