title: Vogt-Koyanagi-Harada's disease in Brazil.
abstract: A retrospective analysis of 33 patients with Vogt-Koyanagi-Harada disease (VKH disease) seen in São Paulo, Brazil, from 1976 to 1985 at a uveitis referral clinic revealed that VKH disease represents 2.5% of the total uveitis cases seen. All cases were bilateral, 30% being men and 70% women. The ethnic distribution was the following: 60% white (with variable Indian or black extraction), 24% darkly pigmented, 9% Orientals (Sansei, third-generation Japanese) and 6% black. The frequency among Orientals was 7 times higher than what would be expected according to the relative frequency of Japanese in the Brazilian population. The age distribution at the onset of the disease was as follows: 12% less than 20 years of age, 60% between 20 and 40 years of age and 27% over 40 years of age. The disease was classified into 3 types with variable extraocular signs. Type I disease was present in 24% of the patients, type II in 51% and type III disease in 24% of the patients. Cataract was present in 40% of the cases and glaucoma was present in 9%. No correlation was found between sex, age at onset, race, type of extraocular involvement and number of extraocular manifestations in considering either visual status or visual prognosis. All patients were treated with systemic steroids. Most of them also received cytotoxic immunosuppressive agents. In this uncontrolled clinical study cytotoxic drug-treated patients seemed to have a better clinical course.
