Eye Movements and Spontaneous Eye‐blink Rate

Abstract

Le systtme vestibulo-oculomoteur est trts fragile. L'alttration de son fonctionnement rtsulte d'une intoxication chronique ou aigue provenant de drogues ou d'agents neurotoxiques. L'augmentation du taux de battement des paupitres est un indice d'imtations sensorielles. Auui bien Ies techniques d'enregistrement des mouvements de I'oeil que plusieurs tests concernant les systbmes optico-moteur et vestibulooculomoteur sont examints a partir de leurs applications en mtdecine du travail.The vestibulo-oculomotor system is very sensitive to injury. Impairment of its function has been described as an effect of chronic or acute intoxication with drugs or neurotoxic agents. An increase in eye-blink rate indicates sensory imtations. Eye-movement recording techniques as well as several tests of the opto-motor and the vestibulo-oculomotor system are outlined and reviewed with regard to their applications in occupational medicine.
