Longitudinal changes in binocular coordination of smooth pursuit in patients with intermittent exotropia after strabismus surgery

Purpose To observe the change in horizontal smooth pursuit in patients with intermittent exotropia before and after strabismus surgery. Methods The smooth pursuit of patients with intermittent exotropia was recorded using a video eye-tracker before and 1 week, and 1, 3, and 6 months after strabismus surgery. Subjects were asked to track a step-ramp target moving at ±6.1°/sec horizontally as accurately as possible under binocular viewing. The...
