To report the clinical presentations, antibiotic sensitivities, management, and outcomes of Enterobacter endophthalmitis.This is a retrospective, consecutive, noncomparative, interventional case series. The medical records of culture-proven Enterobacter endophthalmitis cases from the endophthalmitis registry between January 1995 and March 2006 were reviewed.Enterobacter was the causative agent in 36 culture-proven cases. The causative event was cataract surgery in 11 and trauma in 25 patients. The presenting visual acuity was light perception in 26 eyes (72.2%). Polymicrobial infection was detected in 7 patients (19.4%). Enterobacter organisms were most sensitive to ciprofloxacin (n = 34; 94%), followed by amikacin (n = 31; 86%) and ceftazidime (n = 28; 78%). In postoperative endophthalmitis, final visual outcome of ≥20/200 was achieved in 3 patients (27%) and of ≥5/200 in 5 patients (45%). The eyes became phthisical in 3 patients (27%) and evisceration was carried out in 1 patient. In posttraumatic endophthalmitis, final visual outcome of ≥20/200 was achieved in 5 patients (20%) and of ≥5/200 in 7 patients (28%). The eyes of 11 patients (44%) became phthisical and evisceration was carried out in 1 patient.Enterobacter organisms are mostly susceptible to ciprofloxacin, amikacin, and ceftazidime. Despite this coverage, the visual outcome is often poor.
