Micrococci are gram-positive coagulase-negative cocci that commonly inhabit the soil and are frequently found on the skin and conjunctiva of humans. Although other gram-positive coagulase-negative cocci, such as Staphylococcus epidermidis, are well recognized pathogens in endophthalmitis, similar reports concerning micrococci are lacking. In a study addressing the issue of ocular pathogenicity, micrococci from human conjunctiva failed to produce disease in rabbits after intracorneal injection of twice the dose required to cause corneal infection by S epidermidis from similar sources.1 Nevertheless, Micrococcus has been reported as an opportunist in conjunctivitis2 and in corneal ulcers associated with therapeutic soft contact lens wear.3 We found no model of endophthalmitis.
We report a case of traumatic endophthalmitis associated with an intraocular metallic foreign body.
