• Eighteen patients (21 eyes) with superior oblique palsy had vertical saccadic velocity measurements in primary gaze, adduction, and abduction. No noticeable difference was found when upward saccades were compared with downward saccades in all fields of gaze. Thus, saccadic velocity studies would not be helpful in the diagnosis of superior oblique palsy.
