Ocular toxocariasis presenting as blurred vision and visual impairment

Background: Toxocariasis is a consequence of human infection by Toxocara species larvae. There are symptomatic as visceral and/or ocular and asymptomatic course of toxocariasis. The ocular form is very rare.Objectives: In the current report, we present four cases of ocular toxocariasis who presented with blurred vision and visual impairment caused by retinal inflammation. Ocular larva migrans syndrome were confirmed by serologic diagnosis.Cases presentation: We screened patients diagnosed with ocular larva migrans syndrome between March and June ۲۰۲۱ at the Ophthalmology clinics affiliated with ABZUMS, Karaj, Iran. Detailed demographics, clinical characteristics, and fundus photography were recorded. Anti-Toxocara antibodies in the sera and vitreous fluid investigated by ELISA. Anti-parasite drugs were used to treat all four patients.Discussion: The diagnosis of ocular toxocariasis can be challenging, because both the condition is relatively uncommon and its presentation varies from patient to patient. There are many differential diagnoses such as retinoblastoma, so correct, prompt diagnosis and treatment are very important.
