Uveitis in northern Portugal

Abstract

During the past four years 450 patients (247 female - mean age 36 years and 203 male - mean age 34 years) with intraocular inflammation were evaluated using standard diagnostic criteria, to establish a uveitis survey profile. Patients were divided into four anatomic groups: anterior uveitis (270 cases = 60%), posterior uveitis (108 cases = 24%), panuveitis (54 cases = 12%) and intermediate uveitis (18 cases = 4%). A probable astiological diagnosis was made in 232 cases (51.5%). Rheumatic diseases were diagnosed most commonly (55 cases = 12.2%), mainly ankylosing spondylitis, as is true for other European countries. Ocular toxoplasmosis was a frequent cause of uveitis, as in Brazil and West Africa, thus requiring a prompt diagnosis and treatment. Behçet's syndrome was associated with HLA B5 (65%) as in Japanese and Mediterranean populations. In our area AIDS retinitis is becoming an important differential diagnosis.
