Video Nystagmography (VNG) Test

Have you ever felt like the room is spinning or had trouble maintaining your balance? These symptoms often start in the inner ear, which is responsible for detecting movement and sending signals to the brain to help you stay balanced. If something goes wrong in this system, you may experience vertigo, dizziness, or unsteadiness. Your brain uses both your inner ear and your eyes to maintain balance. If your inner ear isn’t working properly, your eyes make rapid, jerky movements called nystagmus. By studying these movements, doctors can figure out where the problem lies — whether it’s in the ear, the brain, or the nerves connecting them.

Video Nystagmography (VNG) is a specialized test that records your eye movements to help diagnose the cause of dizziness, vertigo, or balance disorders. Since the eyes and inner ear are closely connected in maintaining balance, this test provides critical insights.
