Saccadic binocular coordination in alternating exotropia
We studied the coordination of binocular eye movements in human subjects with alternating exotropia (divergent strabismus). Binocular saccades were recorded in six subjects during binocular and monocular viewing. Subjects were instructed to make saccades between two continuously lit targets (LED's) presented in an isovergence array (with the straight-ahead target 130 cm from the eyes) in a diml...
متن کاملBinocular interactions in rapid saccadic adaptation
An adaptive mechanism controls the strength of innervation to the two eyes independently. However, under some circumstances an adjustment in strength of innervation to one eye is generalized to the other. The coupling and uncoupling of the two eyes during saccadic motor learning was studied using the technique of intrasaccadic target displacements to provide a precise visual-motor error proport...
متن کاملVisual suppression in intermittent exotropia during binocular alignment.
PURPOSE To investigate the cortical mechanisms that prevent diplopia in intermittent exotropia (X(T)) during binocular alignment (orthotropia). METHODS The authors studied 12 X(T) patients aged 5 to 22 years. Seventy-five percent had functional stereo vision with stereoacuity similar to that of 12 age-matched controls (0.2-3.7 min arc). Identical face images were presented to the two eyes for...
متن کاملAlternating exotropia: temporal course of the switch in suppression.
The exotrope usually suppresses the input from the temporal retina of the deviating eye. Some exotropes can alternate the eye which is used to fixate. When this happens, the suppressing and fixating eyes trade roles in what appears to be less than 80 msec (about the time it takes to make a large saccade). The temporal course of this switch in fixating/suppressing eyes was measured by flashing p...
متن کاملAlternating fixation and saccade behavior in nonhuman primates with alternating occlusion-induced exotropia.
PURPOSE Nonhuman primates reared with daily alternating monocular occlusion (AMO) during their first few months of life develop large horizontal strabismus, A/V patterns and dissociated vertical deviation (DVD). In addition, these animals often alternate or switch the fixating eye during binocular viewing. The purpose of this study was to characterize the alternating fixation behavior of these ...
