Colletotrichum graminicola: a new corneal pathogen

Abstract

Purpose: We report the first case of an ocular infection with the fungus Colletotrichum graminicola causing keratitis in a 27-year-old man.

Methods: Twenty-four months after a postoperative course complicated by recurrent fungal keratitis requiring two penetrating keratoplasties, two anterior chamber washouts, a conjunctival flap, and medical treatment with topical natamycin, intracameral amphotericin B, and oral fluconazole.

Results: The patient has shown no signs of fungal recurrence despite a failed corneal graft.

Conclusions: C. graminicola is a new corneal pathogen and should be included in the differential diagnosis of mycotic keratitis.
