Culture-positive endophthalmitis after open globe injuries with and without retained intraocular foreign bodies

Abstract

BACKGROUND AND OBJECTIVE: To report the visual and anatomical outcomes and microbiologic spectrum of culture-positive endophthalmitis in open globe injuries (OGIs) with or without intraocular foreign bodies (IOFBs). PATIENTS AND METHODS: A retrospective, interventional case series of OGIs (n = 718) treated between 2004 and 2015. Patients underwent a management protocol for OGI, including systemic broad-spectrum antibiotics, on presentation. RESULTS: Culture-positive cases of endophthalmitis after open globe repair occurred in 2.1% of eyes (n = 15 of 718 eyes); two eyes had evidence of endophthalmitis on presentation. The most common organism was Staphylococcus species (five of 17 eyes). An IOFB was present in 6.8% of eyes (n = 49 of 718 eyes). All of these eyes received prophylactic intravitreal antimicrobials. In eyes with IOFB, the rate of culture-positive endophthalmitis after initial globe repair was 8.1% (n = 4 of 49 eyes) versus 1.6% (n = 11 of 669 eyes) in eyes without IOFB (P < .01). CONCLUSION: Culture-positive endophthalmitis was identified after OGIs more often in eyes with a concurrent IOFB.
