VNG can objectively record and measure abnormal eye movements associated with peripheral vestibular loss, acoustic neuroma, traumatic brain injury (TBI), Benign Paroxysmal Positional Vertigo (BPPV), vestibular neuronitis, Internuclear Opthalmoplegia (INO) and many other peripheral vestibular and central neurological disorders.

The VisualEyes™ binocular video goggles were designed for enhanced patient comfort and simplified use. For example, with just one click in our Spectrum software, the left and right eye images are visibly centered with no mechanical adjustment of the cameras. The VisualEyes™ VNG is operated using a simple RF remote, providing the examiner freedom to be near the patient rather than at the computer keyboard.
