Some Characteristics of Optokinetic Eye-Movement Patterns: A Comparative Study,
Abstract
Long-associated with transportation ('railroad nystagmus'), optokinetic (OPK) nystagmus is an eye-movement reaction which occurs when a series of moving objects crosses the visual field or when an observer moves past a series of objects. Similar continual movement of the eyes (and head) has been reported to produce an undesired occupational nystagmus. The present study examined responses of animals and men to durations of OPK stimulation varying between 15-120 seconds. Characteristics of the animal responses differed considerably from those of men in both the horizontal and vertical planes. The data were compared with vestibular eye-movement patterns (those which can blur vision during 'pilot's vertigo') to differentiate aspects of the eye-movement responses which can be attributed primarily to vestibular rather than oculo-motor origins.
