Etiology of Endogenous Uveitis in Childhood

102 children with uveitis were followed up in both an ophthalmological clinic and in private practice. These cases were studied, using the same criteria for the anatomical and etiological classification. For each etiology arguments for certitude and probability were cautiously defined. The etiology could be ascertained in about 36.5% of the cases. Arguments for a presumptive etiology were found in about 23.1% more cases. The first cause was toxoplasmosis; the second cause was streptococcic hypersensitivity. An etiology was rarely found for intermediate uveitis.
