PURPOSE The effects of impaired spatiotemporal vision in amblyopia on visuomotor skills have rarely been explored in detail. The goal of this study was to examine the influences of amblyopia on visually guided reaching. METHODS Fourteen patients with anisometropic amblyopia and 14 control subjects were recruited. Participants executed reach-to-touch(More)
PURPOSE To examine the effects of anisometropic amblyopia on the temporal pattern of eye-hand coordination during visually-guided reaching. METHODS Eighteen patients with anisometropic amblyopia and 18 control subjects were recruited. Participants executed reach-to-touch movements toward visual targets under three viewing conditions: binocular, monocular(More)
PURPOSE Impairment of spatiotemporal visual processing is the hallmark of amblyopia, but its effects on eye movements during visuomotor tasks have rarely been studied. Here the authors investigate how visual deficits in anisometropic amblyopia affect saccadic eye movements. METHODS Thirteen patients with anisometropic amblyopia and 13 control subjects(More)
OBJECTIVE To investigate whether static ocular counterroll (OCR) gain is reduced during viewing of an earth-fixed vs a head-fixed target. METHODS Twelve healthy individuals were recruited. The target consisted of a red fixation cross against a grid pattern at a viewing distance of 33 cm. The target was mounted on a wall (earth fixed) or was coupled to the(More)
