Patient being tested with VideonystagmographyVideonystagmography (VNG) is a technology for testing inner ear and central motor functions, a process known as vestibular assessment. It involves the use of infrared goggles to trace eye movements during visual stimulation and positional changes. VNG can determine whether dizziness is caused by inner ear disease, particularly benign paroxysmal positional vertigo (BPPV), as opposed to some other cause such as low blood pressure or anxiety.

VNG testing is more accurate, more consistent and more comfortable for the patient. By having you more comfortable and relaxed, consistent and accurate test results are more easily achieved.
