Fundus examination revealed ipsilateral hyperaemic optic disc oedema, and the patient was admitted with the presumptive diagnosis of left optic neuritis. Subsequently, during follow-up, the patient developed a retinal granulomatous lesion in the superior temporal arcade with vitritis and fibrotic strands extending to the mid-periphery. Serum antibodies detection by ELISA and aqueous humour immunoblot were positive for Toxocara canis. Medical therapy with albendazole and oral steroids was instituted with satisfactory results. One year later, a new macular lesion developed with consequent vision loss. ER -
