Postoperative Endophthalmitis


Postoperative endophthalmitis is defined as severe inflammation involving both the anterior and posterior segments of the eye after intraocular surgery. Typically, postoperative endophthalmitis is caused by the perioperative introduction of microbial organisms into the eye either from the patient’s normal conjunctival and skin flora or from contaminated instruments. Once organisms gain access to the vitreous cavity, overwhelming inflammation is likely to occur, making rapid recognition, diagnosis, and treatment critical in optimizing final outcomes. Although most cases of postoperative endophthalmitis occur within 6 weeks of surgery, infections seen in high-risk patients or infections caused by slow-growing organisms may occur months or years after the procedure.
