Videonystagmogram Test in Dallas, TX
Videonystagmogram test (VNG) is a test that is used to check for a specific type of involuntary eye movement called nystagmus.
Nystagmus occurs when your eyes move involuntarily or uncontrollably up and down or side to side or both. These involuntary movements can be slow or fast, steady or jerky.
The cause of these involuntary movements in your eyes is due to conflicting messages received by your brain from your eyes and the balance system in your inner ear.
Nystagmus can occur briefly when you move your head in certain directions or look at some types of patterns. If you experience nystagmus when you’re not moving your head or if it lasts for a long period of time, it may mean that you have something different. It could mean that you have a disorder of the vestibular system.
Organs, nerves, and structures in the inner ear all make up the vestibular system. The vestibular system is your body’s main center of balance.
Videonystagmography evaluation can be used to evaluate the function of the vestibular system.
