Adult toxocariasis. Uniocular retinal lesions in the 20- to 50-year age group.

Uniocular posterior polar lesions thought to be characteristic of suspected adult ocular toxocariasis have been observed in a group of eight patients whose ages ranged from 20 to 50 years. Six patients had positive fluorescent antibody tests for Toxocara species, whereas control serological studies showed that only 4% of healthy adults in the same age group had positive fluorescent antibody responses. All the patients with clearly defined progression of their retinal lesions had positive fluorescent antibody tests. In two patients positive tests reverted to negative within 2 years.
