Objective: To describe clinical, image, and laboratory findings in patients with eye toxocariasis seen in three of the main ophthalmology services in three national hospitals in Lima, Peru.   Material and method: records of patients with a presumptive diagnosis of ocular toxocariosis between January 1997 and January 2010 in Cayetano Heredia National Hospital, Arzobispo Loayza National Hospital and the Instituto Nacional de Salud del Niño (national reference center for sick children).   Results: Forty-one cases were found. Their ages were between 5 moths and 62 years (11.6 ± 8). The most frequent symptom was reduced visual acuity. Most frequent findings in eye funduscopy and image studies were peripheral granulomata and posterior uveitis.Most patients had positive serology tests for Toxocara canis.   Conclusions: Most patients in this review ere childr...

Toxocariasis is an infection caused by nematode larvae from Toxocara genus, and the most important infective agents for humans are Toxocara canis and Toxocara cati, parasites from dogs and cats, respectively. Toxocara species belong to Ascaridida order, Ascaridodea super-family, Toxocaridae family. The disease in humans is mainly caused by T. canis. Human toxocariasis was described for the .rst time by Wilder in 1950, who identi.ed a then-unknown nematode in a child presenting with a granulomatous lesion in one of his eyes. In 1952, Beaver reported cases of a multi-systemic, chronic, and sever disease, associated to hypereosinophilia. In Peru, in 1991, Maguiña et al. reported the very.rst cases of visceral larva migrans, and in 1999, Miranda et al. reported the very .rst cases of ocular larva migrans.
