Case report: Toxocariasis of the optic disc after eating raw meat

There are a few reports of OCT findings in ocular toxocariasis, according to the authors of this case report, but to the best of their knowledge this is the first report of Toxocara overlying the optic nerve.

A healthy 46-year-old man presented with decreased vision in his right eye after eating raw meat. Funduscopic examination showed a cystic lesion on an edematous right optic disc with adjacent serous retinal detachment. OCT confirmed a peripapillary serous retinal detachment and a well-demarcated cystic lesion in the right eye. The patient had moderate eosinophilia and was seropositive for anti-Toxocara IgG antibody.

Diagnosed with ocular toxocariasis, he was treated with systemic corticosteroids and albendazole. Subsequently, his vision and fundus appearance improved.
