Surgical management for abnormal head position in nystagmus: the augmented modified Kestenbaum procedure.

Patients with nystagmus and an eccentric null point in lateral gaze may assume an abnormal head position to maximise visual acuity. Surgical procedures for this condition can result in significant undercorrection of the head turn. A follow-up of 15 patients for an average of 33 months revealed a sustained improvement in head position with the use of the augmented modified Kestenbaum procedure.
