Abstract

The objective of this study was to determine ocular manifestations of toxocariasis in schoolchildren. A study was conducted in two schools in the Anzoátegui state in Venezuela in 2019. The ELISA test was used to determine IgG antibodies against Toxocara spp. The families completed a questionnaire, and the children were clinically evaluated by pediatricians and ophthalmologists. 118 children participated, 18.6% presented anti-Toxocara spp. The clinical manifestations with a statistically significant association were allergic reactions, epiphora, and decreased visual acuity. The ophthalmological evaluation found keratitis, uveitis, iritis, retinal granuloma, endophthalmitis, amaurosis, leukocoria, retinal detachment and endotropia. The findings show a high frequency of eye disease in children with toxocariasis from a state of Venezuela.
