VNG Testing

For the VNG test, goggles are placed on the patient while an infrared camera connected to a computer measures nystagmus (eye movement) during different types of stimulation (visual, positional and caloric). A pattern of eye movement is recorded, producing data from which the practitioner is able to determine whether the pathology is of central or vestibular origin, whether it is ocular-motor, or whether the patient has benign paroxysmal positional vertigo (BPPV).

VNG analyzes the cause of a patients balance disorders by testing oculo-motor responses to visual, positional and caloric stimulus. The patients oculo-motor response is measured against objective criteria, and the practitioner receives an objectively measured assessment that differentiates between peripheral and central vestibular pathology. Results appear on the screen and a printout of normative data and the patients results are generated for the patients medical record.
