Videonystagmography VNG

Videonystagmography (VNG)

Videonystagmography (VNG) is a test designed to help determine the source of your dizziness or unsteadiness. During the test, you will wear infrared goggles that record your eye movements. The test consists of visual tasks, sitting and laying in different positions, and calorics. For caloric testing, the ears are irrigated with warm and cool air to assess the function of the inner ear. Many people experience some dizziness during the test; however, the dizziness is of short duration and usually subsides by the completion of the test. The test takes approximately 1 hour to complete.
