Videonystagmography (VNG)

Videonystagmography (VNG) is a diagnostic tool used to evaluate and analyze eye movements, particularly in relation to vestibular function and balance disorders. This non-invasive test involves the use of infrared video cameras to monitor eye movements while the patient undergoes various vestibular stimuli, such as changes in head position or exposure to different visual cues. By precisely tracking the movements of the eyes, VNG can aid in the diagnosis of conditions like vestibular neuritis, Meniere's disease , benign paroxysmal positional vertigo (BPPV), and other vestibular disorders. VNG provides valuable information about the function of the vestibular system, helping clinicians to pinpoint the underlying cause of balance problems and tailor treatment plans accordingly, which may include vestibular rehabilitation therapy or medication management.
