Purpose: The objective of this study was to evaluate the incidence, predisposing surgery, management and final visual outcome of postoperative endophthalmitis over a 14–year period at our institute. Methods: This retrospective study reviewed all intraocular surgeries performed between January 1, 1991 and August 31, 2004 at Chang Gung Memorial Hospital, Kaohsiung Medical Center, for the occurrence of nosocomial acute–onset of postoperative endophthalmitis. Results: The overall incidence of postoperative endophthalmitis after intraocular surgery was 0.19%( 56/30,219 ). Postoperative endophthalmitis developed in 56 eyes of 56 patients during the study period: The condition developed after cataract surgery in 46 eyes, after penetrating keratoplasty in 6 eyes, after filtering surgery in two eyes, after secondary intraocular lens implant in one eye and after vitrectomy in one eye . Postoperative endophthalmitis was culture positive in 31(55%) cases. The most frequent organism isolated was coagulase–negative Staphylococcus. Factors associated with better visual acuity outcomes included low virulence of isolated pathogen, initial visual acuity of counting fingers or better, and history of cataract surgery compared to other intraocular surgery. Conclusions: The overall incidence of endophthalmitis after intraocular surgery was 0.19%. The results of this 14–year review from a local medical center may serve as a source of comparison for other centers and future studies.
