Videonystagmography (VNG) is a test that measures a type of involuntary eye movement called nystagmus. These movements can be slow or fast, steady or jerky. Nystagmus causes your eyes to move from side to side or up and down, or both. It happens when the brain gets conflicting messages from your eyes and the balance system in the inner ear. These conflicting messages can cause dizziness. To know everything about VNG Test in Orlando, Visit https://www.mymdds.com/
