Although Mycobacterium fortuitum is being incriminated with increasing frequency as the cause of both minor and major infections in man, only two ocular infections by this acid-fast bacillus have been recorded. Both followed corneal injury by foreign bodies. The present paper records two new infections by M fortuitum, one of which was apparently superimposed on a very long-standing, recurrent ulcerative keratitis of undetermined cause, while the other followed penetrating keratoplasty for keratoconus. The infection led to perforation of the cornea and enucleation of the eye in the former; it was controlled by debridement and specific therapy in the latter.
