Vestibular Assessment

Videonystagmography (VNG) is used to evaluate patients with dizziness, vertigo, or balance dysfunction.  This test allows us to assess the connection between the inner ear and eye movements through a reflex called the vestibulo-ocular reflex, providing an objective assessment of the oculomotor and vestibular systems.  This test consists of three parts and requires the use of goggles to track and record eye movement:  oculomotor evaluation, positioning/positional testing, and caloric stimulation of the vestibular system.  Data obtained from this process allows us to determine potential causes of symptoms for patients allowing for improved referral and/or treatment of symptoms.
