Videonystagmography (VNG) is a non-invasive exam that records eye movements to assess the vestibular, or balance, system. Based on the video monitoring of eye movements, the VNG allows for more precise measurements than older electrode-based ENG systems. At Atlantic Ear, Nose & Throat we use state-of-the-art equipment and the latest techniques to diagnose and treat your balance conditions.What does the test involve?
The VNG test is composed of three sections with infrared video cameras recording your eye movements in response to different stimuli. The first portion involves watching and following a series of lights and dots as they move in different patterns. For the second portion of the VNG, you will be asked to place your head and body into different positions while lying on an examination table. Finally, while wearing special VNG goggles, your ears will be irrigated with cool and warm water. During this portion of the test, it is likely that you will feel some dizziness. This feeling only lasts a few minutes, but the VNG gives us a great deal of information about your vestibular system. Both the computer and the audiologist will analyze the results of your VNG to determine if each ear's vestibular system is functioning properly.What are some common causes that can affect the inner ear?
Benign paroxysmal positional vertigo
Inflammation in the inner ear
Motor or visual disturbances
Aging of the balance system
