Saccadic eye velocity in concomitant divergent squint.

Study was conducted on 10 normal subjects, 20 cases of unilateral divergent squint and 20 cases of alternating divergent squint. In unilateral divergent squint cases lateral rectus of nondominant eye showed overactivity on fixation with dominant eye. In the alternating divergent squint cases which had onset of squint at or after the age of 2 years showed increased saccadic velocity of medial rectus of non-dominant eye on fixation with dominant eye. Working hypothese have been suggested to explain these phenomena.
