Ocular complications as a form of presentation of toxocariasis

Abstract

Toxocariasis is a prevalent zoonosis with a significant socioeconomic impact, particularly in poor communities around the world. It is caused by larval forms of nematode species, parasites of the Toxocara genus. The spectrum of clinical manifestations in toxocariasis varies widely from asymptomatic cases to systemic infections. In the case of ocular toxocariasis, impaired visual acuity is the most common manifestation when symptoms are present. Ocular presentations include chronic endophthalmitis, posterior pole granuloma, or a peripheral granuloma. We present the case of a 12-year-old patient with ocular toxocariasis in the form of a posterior pole granuloma with vitreous tractional bands, which is accompanied by a hyperpigmented lesion in the macular area in the healing phase. The purpose of our publication is to highlight the multiple ocular complications that can occur in patients with ocular toxocariasis, which ultimately lead to irreversible visual loss.
