The postoperative endophthalmitis is a rare and serious complication of the intraocular surgery, which may result in the loss of the visual function. Retrospectively, the authors reviewed the 14 postoperative endophthalmitis cases at the department of ophthalmology of Geneva between 1983 and 1992. For cataract extractions, the following incidence was observed: 0.115% (8 of 6954 cases). In 36% (5 of 14 cases), the culture was positive. The best treatment was a early vitrectomy associated with antibiotherapy. In 57% (8 of 14 cases), the visual outcome was equal to or better than 0.2.
