Videonystagmography (VNG) Testing
VNG testing assesses the vestibular (balance) system by tracking a patient’s eye movements using infrared cameras attached to goggles. During the assessment, the patient will be asked to move his or her head and body into certain positions and instructed to look at various objects. The final part of the assessment also involves blowing cool and warm air into each ear canal to stimulate the peripheral vestibular system (inner ear) directly. This final part may result in a temporary turning sensation that will only last a few minutes.
