Ocular findings in children with congenital toxoplasmosis

Purpose: This study aimed to know the most common ocular findings in children with congenital toxoplasmosis. Methods: This is a retrospective study carried out from a historical cohort, with a quantitative approach. We evaluated children referred to a pediatric infectious disease service and included only those with confirmed diagnosis of congenital toxoplasmosis. The ophthalmologic evaluation included regular fundus examination under pupil dilation. Results: Of 58 children presumably exposed to risk of the disease during the pregnancy, 20 had ocular lesions during the first year of life (34 eyes). Of these, 12 were asymptomatic at birth. Strabismus was noted in 14 children (70%). In one child there was ptosis, and another had decrease in the palpebral fissure (microphthalmia). Retinochoroiditis was the most common complication, present in all 20 children. Seven children (35%) showed unilateral changes and 13 children showed bilateral changes (65%), with emphasis on the location in the posterior pole and macula. Conclusion: Retinochoroiditis and strabismus were outstanding as important sequelae of congenital toxoplasmosis.
