Diagnostic Aspects and Retinal Imaging in Ocular Toxocariasis : A Case Report from Italy

Abstract EN

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.
