To present an atypical case of ocular toxocariasis with favorable outcome without treatment, monitoring with optical coherence tomography (OCT) and wide field retinographies.
Retina and vitreous service of a tertiary hospital in Spain.
Description of a clinical case, follow up and imaging examinations.
16 year old male patient who complains of central white scotoma with his left eye since 1 day ago. Best corrected visual acuity (BCVA) was 1.0 in his right eye and 0.5 in his left eye. The funduscopy revealed a raised white spot in te fovea centralis without vitritis. The optical coherence tomography (OCT) performed the day of the visit revealed a peculiar vermiform image in the fovea with associated macular edema. Blood tests revealed eosinophilia and positive IgG anti-Toxocara canis. Follow up at 2 weeks the patient had BCVA of 1.0 in both eyes and the macular OCT revealed completely normal profile and the wide-field retinography showed an immage suggestive of the parasite floating in the peripheral vitreous. At 4 months follow-up the patient was asymptomatic with normal imaging examinations.
Ocular toxocariasis is a rare parasitic disease that manifests classically as posterior pole granuloma or endophthalmitis, having a poor visual prognosis in all cases. In this particular case we highlight the usefulness of imaging exams when performed in the same time of consultation and not derived for another day. This is useful especially in parasitic diseases, where the structure of the lesions can quickly change as we have seen. We can also conclude that ocular toxocariasis can sometimes be a self-limited and good visual prognosis disease. The self-limiting ocular toxocariasis presentation has not been described to date.
