Exclusion criteria included intravitreal injection or intraocular surgery in the 30 days prior to injury or less than 30 days of follow-up. A total of 586 out of 993 open globe injuries were included in the study. The main outcome measure was the rate of endophthalmitis.Results: In this study, 25/586 eyes (4.3%) had endophthalmitis. Of these, 12/25 eyes (48.0%) presented with endophthalmitis and 13/25 eyes (52.0%) developed endophthalmitis after globe closure. Multivariate analysis identified time to globe repair (OR 4.5, CI 1.9– 10.7, p = 0.0008), zone I injury (OR 3.6, CI 1.1– 11.0, p = 0.0282), and need for additional surgery (OR 5.5, CI 1.5– 19.7, p = 0.0092) as factors associated with increased risk of developing endophthalmitis. Subconjunctival antibiotic injection at the time of globe closure (OR 0.3, CI 0.1– 0.7, p = 0.0036) was associated with decreased risk of developing endophthalmitis.Conclusion: Prompt globe closure and subconjunctival antibiotics may reduce the risk of endophthalmitis in OGI. Furthermore, our practice of a one-time dose of systemic prophylactic antibiotics, and intravitreal antibiotics if intraocular foreign body (IOFB) removal is delayed, was not found to increase the rate of endophthalmitis.Keywords: endophthalmitis, intraocular foreign body, ocular trauma, open globe injury
