Atypical mycobacterial infections of the cornea are rare. Recently, an increasing number of cases have been reported following outpatient office procedures,1 injury with foreign bodies, or intraocular surgery.2 The majority of these infections have been caused by group IV, rapidly growing organisms Mycobacterium fortuitum and Mycobacterium chelonae. To our knowledge, there has been only one case report of keratitis caused by Mycobacterium gordonae, a group II, slowly growing organism.2 We describe a patient who developed M gordonae keratitis following penetrating keratoplasty.
