Toxocara canis is a nematode parasite, commonly found in dogs. This roundworm parasite can invade the eye, causing visual impairment. Toxocara should be considered as a possible causative agent of posterior and diffuse uveitis, and it could be considered in the differential diagnosis of retinoblastoma. Ocular manifestations vary from severe endophthalmitis to silent incidental findings on a routine examination. We report a case of ocular toxocariasis in a 24-year-old Asiatic female that presented to us complaining of visual impairment. Fundoscopic examination revealed a posterior pole granuloma and exudative retinal detachment along with exudates. Presentation, clinical findings, morphological changes, and treatment are discussed. The enzyme-linked immunosorbent assay serology for Toxocara canis was performed, demonstrating the positivity for IgG and IgE. Treatment with the antihelminthic albendazole was initiated. Fluorescein angiography (FA; HRA 2, Heidelberg engineering) and optical coherence tomography (OCT; Spectralis, Heidelberg tomography) were performed, and results have been reported. 1
