VIDEONYSTAGMOSCOPY - ITS USE IN THE CLINICAL VESTIBULAR LABORATORY

Vestibular function of a population including labyrinthine-defective p atients and a control group of age-matched normal healthy volunteers w as evaluated using videonystagmoscopy. This device is made of one or t wo CCD infra-red cameras mounted on diving glasses and allows observat ion of ocular movements on a video monitor and/or recording on a video tape. Eye movements are observed after rotations in a Barany chair and during passive head tilts. With this simple and non-invasive test, a screening of vestibular function al bedside or during ENT clinical inv estigations can be performed. A further study with videonystagmography to quantify these results being prepared.
