Endophthalmitis caused by an Erwinia species.

A 14-year-old boy developed exogenous endophthalmitis presumably caused by an Erwinia species. To our knowledge, this is the firs reported case of endophthalmitis caused by an Erwinia species, which has been considered pathogenic for only the last ten years. The endophthalmitis developed after a piece of wood penetrated the patient's sclera. After removal of the foreign body, the patient received intravitreally and subconjunctivally administered gentamicin sulfate, intramuscularly administered cephaloridine, and a short course of orally administered prednisone. The patient had clinical and visual improvement.
