Videonystagmography (VNG)

Explanation

Videonystagmography, or VNG, records involuntary eye movements to assess part of the balance system.

What happens during VNG?

VNG stands for videonystagmography. Cameras in goggles record nystagmus, which means eye movements that happen without conscious control. Testing may track the eyes while you look at targets, change position, or receive warm or cool air or water in the ears.

What can the result show?

Eye movements provide information about signals from the inner ear and parts of the nervous system involved in balance. An unusual result can help guide further assessment, but VNG alone does not identify every cause of dizziness or establish one diagnosis.
