The data of 750 consecutive uveitis patients who visited the uveitis department of the Rotterdam Eye Hospital were analysed by computer. Anterior uveitis was diagnosed most frequently (52%), mostly the acute form. We found a high percentage of Fuchs' heterochromic iridocyclitis and HLA-B27+ iridocyclitis. In the posterior uveitis group appeared the more recent clinical entities such as acute retinal necrosis, Birdshot retinochoroidopathy, CMV-retinitis, AMPPE and ocular candidiasis. Ocular Toxoplasmosis was still the leading cause in this group. These data will be compared with other studies of similar populations. Factors influencing frequency of subtypes of uveitis and bias of this study will be discussed.
