We studied 51 patients who developed Vogt-Koyanagi-Harada (V-K-H) syndrome after corticosteroid therapy. The final visual acuity was better than 6/15 (20/50) in 50%, and less than 6/60 (20/200) in 25% of the patients. The severity and extraocular manifestations of this disease also appeared to be less than observed in patients before the clinical use of corticosteroids. Corticosteroid therapy probably altered the clinical picture in this disease, although other possibilities, including a skewed patient population, may account for these differences.
