Surgical treatment of supranuclear and internuclear ocular motility disorders

Patients with supranuclear and internuclear ocular motility disorders may have nystagmus and oscillopsia, or need to adopt an abnormal head posture to either fixate or maintain binocularity, Many have a cosmetically unsatisfactory appearance, In addition, because of lesions involving ocular motor nuclei or nerve fascicles, double vision is also a common problem, The usual management of these patients is symptomatic with occlusion or prisms, We report on 11 patients who underwent extraocular muscle surgery with the aim of reducing symptoms and restoring or improving binocular single vision, Three patients had bilateral internuclear ophthalmoplegia with exotropia, 3 had dorsal midbrain syndrome, 2 had residual upgaze palsies after cerebral vascular accidents, 2 had oculopalatal myoclonus and one skew deviation, After surgery, symptoms, visual function and cosmesis improved in nearly all patients, We recommend that surgery should be considered more readily in the rehabilitation of these patients.
