Optic Tract Syndrome

Twenty-one patients with lesions compromising the optic tract were reviewed. The involvement of the optic tract may be diagnosed in the presence of highly incongruous hemianopia, an afferent pupillary defect, and characteristic atrophy of the optic discs. Behr's pupil, hemianopic pupillary reaction (Wernicke's sign), and associated major neurologic deficits were encountered rarely.
