title: Atypical Cogan's syndrome: a case report.
abstract: Cogan's syndrome is a rare presumed autoimmune disorder characterized by nonsyphilitic interstitial keratitis and progressive audiovestibular symptoms. The initial report by David G. Cogan in 1945 was modified by Haynes et al in 1980 who proposed diagnostic criteria for patients with other ocular or vestibular symptoms and suggested this to be atypical Cogan's syndrome. In a more typical presentation of Cogan's syndrome, ocular and audiovestibular signs and symptoms usually appear alone and are bilateral. We report a case of 50-year-old woman with an atypical Cogan's syndrome manifested by unusual relatively rapid clinical deterioration.
