A Case of Ocular Larva Migrans Caused by Toxocara canis Infection with Mild Eosinophilia

Abstract

We report a case of intraocular toxocariasis in a 45-year-old man who presented with impaired visual acuity of the left eye. He denied a trauma history on his eyes. He had been entirely free of ophthalmic symptoms until hospitalization. Mild peripheral eosinophilia was present. Fundus photography revealed a round, yellow-white, and solid intraretinal granuloma of 1/2 disc in diameter at the posterior pole of the left fundus. Aqueous humor aspiration was perforemed. We have preformed ELISA using T. canis excretory-secretory antigen and found higher antibody titers in the aqueous humor and the serum. At 4 weeks after combined prednisolone and albendazol therapy, the size of granuloma was decreased. The patient's visual acuity of the left eye improved from 20/200 to 20/30.
