Mycobacterium gordonae keratitis.

A 20-year-old man was evaluated for an indolent corneal ulcer. Tissue and cultures from a penetrating keratoplasty indicated that the causative agent was Mycobacterium gordonae. This is the third patient reported with M. gordonae keratitis, although there have been numerous reports of nontuberculous mycobacterial keratitis. Nontuberculous mycobacterial keratitis is typically associated with previous trauma. The patient reported here had no known predisposing factor.
