Purpose

To portray the current scene of endophthalmitis in a multispecialty ophthalmology department regarding etiologies and treatment guidelines.

Methods

Retrospective chart review of all patients diagnosed with endophthalmitis or suspected endophthalmitis from 2009 to 2012.

Results

A total of 24 eyes were diagnosed with endophthalmitis or suspected endophthalmitis during a 4-year period. The etiologies included endogenous endophthalmitis (6), blebitis (3), Ahmed valve implantation (3, 2 of them with late infection), postcataract surgery (3), intravitreal injections (4), penetrating injury (2), and other surgical procedures (3). Of the postcataract surgery cases, 1 was a congenital cataract surgery, and 2 were referrals. There were no endophthalmitis cases in 4603 adults undergoing cataract surgery in our department during this period. There were 14 positive cultures: 1 was candida and the rest bacteria. Ten of the bacteria cases were Gram-positive cocci (predominantly strep species), 3 were Gram-negative, and coagulase negative staphylococci were detected in 2 cases.

Conclusions

Our study indicates a significant change in the case mix of endophthalmitis. The past leading cause, cataract surgery, was dramatically reduced, and intravitreal injections became a major cause. The change in etiologies, and possibly in the microbial flora, warrants reconsideration of the rules that guided the management of endophthalmitis since the Endophthalmitis Vitrectomy Study.
