Transient ocular deviations with eyes closed during head turning were compared with those during rotation of head and trunk together. These deviations were more frequent(68.7%) and larger (26.7°±7.1°) during head turning than during trunk rotation (19.6%, 13.5°±6.8°). Moreover, eye shifts of more than 20° were seen during small degrees of head turning(10°). These results indicate that transient ocular deviation in the same direction as head turning is not cervico-ocular reflex but saccadic movement related to eye-head coordination which is elicited against VOR mainly by the input from neck proprioceptors and activation of the lateral gaze center while the eyes are closed.
