Epidemiology of uveitis in Switzerland

Abstract

During the period from January 1990 to December 1993, 558 new patients (250 female and 308 male, mean age 44 years; range 5-92) were seen at the Uveitis Clinic of the Hopital Jules Gonin. These 558 patients (740 eyes) were subdivided into anterior uveitis (343 patients-61%), intermediate uveitis (57 patients-10%), posterior uveitis (118 patients-21 %) and panuveitis (40 patients-7%). The incidence of uveitis for the referral area considered was calculated to be 17.5 per 100,000 inhabitants per year. A specific diagnosis was found in 386 cases (69%). The most frequently diagnosed entities were HLA-B27-associated acute anterior uveitis (89 cases-15.9%), uveitis associated with acute herpes zoster ophthalmicus (54 cases-9.7%), toxoplasmosis (53 cases-9.5%), sarcoidosis (33 cases-5.9%), typical pars planitis (31 cases-5.6%), Fuchs' heterochromic cyclitis (30 cases-5.4%), herpetic anterior uveitis (23 cases-4.1 %) and acute retinal necrosis (13 cases-2.3%). Incidence and distribution of most disease entities correspond to those of other European and American series.
