Demographic variables, maternal and infant serology and the results of the ophthalmological examination were collected. Data were analyzed in SPSS v21 Results: 46.4% of 125 infants had OT, of them 67.2% were female, (p = 0.04) the median age was 6 months, 41% had IgG and IgM positive. The lesions were bilateral in 82.8%, central in 86.2%, and inactive in 81%. Retinochoroiditis was accompanied by strabismus in 41%. CONCLUSIONSThe frequency of OT in this population of infants with congenital toxoplasmosis was high. more than 80% of the eye lesions were inactive, centrally located and bilaterally involved.
