【 摘 要 】

To determine the prevalence of ocular toxoplasmosis among the general population of the district of Santa Rita de Cassia, Barra Mansa, State of Rio de Janeiro, a cross-sectional study on 1,071 individuals was performed. These subjects underwent serological tests (anti-Toxoplasma IgG and IgM) and physical and ophthalmological examinations. The diagnosis of presumed ocular toxoplasmosis was based on clinical and serological criteria and the appearance of the retinochoroidal lesion. The lesions were classified into three morphological types: 1. Limits marked with a halo of hyperpigmentation and an area of central chorioretinal atrophy; 2. Hypopigmented halo and hyperpigmented central area; and 3. Hyperpigmented or hypopigmented. The prevalence of healed lesions compatible with ocular toxoplasmosis was 3.8% among the general population and 5.8% among individuals who were seropositive for Toxoplasma gondii (65.9% of the individuals evaluated). Type-1 lesions (41.5%), female sex (68.3%), peripheral lesions (58.5%) and lesions smaller than three disc diameters predominated.
