VNG Test
VNG Test (Videonystagmography)
The VNG Test (Videonystagmography) is an advanced diagnostic test used to evaluate vertigo, dizziness, balance disorders, and inner ear vestibular problems. It helps specialists understand how the inner ear balance system and the brain work together by recording involuntary eye movements called nystagmus through special infrared goggles.
At our audiology and balance clinic, the VNG test is performed using modern computerized equipment by experienced specialists. This test is highly effective in diagnosing conditions like BPPV, vestibular neuritis, Ménière’s disease, labyrinthitis, and other balance-related disorders.
How the VNG Test Works
During the procedure, the patient wears special video goggles that track eye movements. The test is usually divided into three parts:
- Oculomotor Testing – checks eye tracking and visual response
- Positional Testing – checks dizziness caused by head movements
- Caloric Testing – warm and cool air or water is used to stimulate each ear individually
The complete test is safe, non-invasive, and usually takes 45–60 minutes.
