Epidemiological characteristics of uveitis in Switzerland

Abstract

Since January 1990, data from uveitis patients have been systematically stored in a computer data bank. During the period from January 1990 to March 1993, 435 new patients (185 female and 250 male, mean age 43 years; range 6-92) were seen at the Uveitis Clinic of the Hôpital Jules Gonin. These 435 patients (630 eyes) were subdivided into anterior uveitis (268 patients--62%), intermediate uveitis (47 patients--11%), posterior uveitis (89 patients--20%) and panuveitis (31 patients--7%). The incidence of uveitis for the referral area considered was calculated to be 17 per 100,000 inhabitants per year. A specific diagnosis was found in 312 cases (72%). The most frequently diagnosed entities were HLA-B27-associated acute anterior uveitis (67 cases--15.4%), uveitis associated with acute herpes zoster ophthalmicus (40 cases--9.2%), toxoplasmosis (39 cases--9%), typical pars planitis (29 cases--6.7%), sarcoidosis (29 cases--6.7%), Fuchs' heterochromic cyclitis (27 cases--6.2%), herpetic anterior uveitis (21 cases--4.8%) and acute retinal necrosis (11 cases--2.5%). Incidence and distribution of most disease entities correspond to those of other European series.
