VNG (videonystagmography)
Videonystagmography “V” using video and an infrared camera, “N” nystagmus or involuntary eye movements, “G” to graph measurements. The use of video goggles accurately documents eye movement using infrared signals. With this technology we can not only measure the eye movements, but we can see them and capture video of their movement.
Your eye movements are directly related to what your inner ear (semicircular canals) is doing. They are the window into the function of the balance system. During the test you will be asked to follow a light with your eyes while the movements of your eyes are being monitored. Then you will be moved in different simple body positions to determine if your balance system is responding normally. Finally the audiologist will present cool and warm air to your ear canals. This will give you a sensation of spinning for a short time while your eye movements are being recorded. This test helps us to determine how well your vestibular systems are functioning. The audiologist will analyze the test and send the results to the referring physician for review.
