Saccadic velocity measurements in Brown's syndrome.
Eleven patients with Brown's syndrome (12 eyes) had vertical saccades measured in the primary, adducted, and abducted positions. Upward saccades in all 3 positions were equal and within the normal average velocity range. There was no difference between upward velocities in the eyes with Brown's syndrome when compared with the opposite, normal eye. These findings are consistent with the restrictive etiology of Brown's syndrome and may be helpful in confirming the diagnosis in some patients.
