VNG (Videonystagmography) is a test that assists your physician in diagnosing dizziness, unsteadiness or other problems with balance and coordination. The test consists of recording eye movements during a variety of circumstances including the application of warm and cool air to your ears. The test takes 60-90 minutes, is performed by a technologist and is interpreted with the assistance of a computer.
