Abstract
Although oculomotor control appears to normalize during successful orthoptics therapy for amblyopia, reports providing a quantitative analysis of eye movements during extended periods of treatment are lacking. For the 1st time such a report in an adult amblyope is proposed. Aspects of eye movement control that tended to normalize with therapy include drift amplitude and velocity, duration and frequency of steady fixation and pursuit gain. Smooth pursuit control can apparently be modified, even in an adult amblyope. Aspects of eye movement control that remained abnormal throughout therapy, in spite of normalization of visual acuity and centralization of fixation, include increased saccadic latencies, use of large saccades during small-amplitude pursuit tracking and static overshooting. Certain aspects of saccadic and pursuit control apparently could either no longer be modified or would require longer periods for this to occur.
