BACKGROUND: There are currently no standardized treatment guidelines for endogenous bacterial endophthalmitis. We report the long-term outcomes of early intravitreal treatment of endogenous bacterial endophthalmitis, defined as intravitreal and systemic antibiotics administered within 24 h of diagnosis, with conservative use of pars plana vitrectomy. DESIGN: Interventional retrospective case series. PARTICIPANTS: Consecutive patients treated for culture-proven endogenous bacterial endophthalmitis between 2001 and 2008 at the Weill Cornell Medical Center. METHODS: The clinical records of 18 eyes from 13 patients were reviewed. MAIN OUTCOME MEASURES: Visual acuity. RESULTS: Mean age at presentation was 61 (25-85) years. All patients had underlying medical conditions. Extraocular infectious foci were identified in nine (69%) patients, with endocarditis being the most common. Gram-positive organisms were identified in 12 (92%) patients, including five with methicillin-resistant Staphylococcus aureus. No cases were misdiagnosed. Final visual acuities of better than 6/120 and counting fingers were achieved in 6 (55%) and 7 (64%) of 11 eyes, respectively. Longer time between onset of ocular symptoms and intravitreal antibiotic injection correlated with worse visual outcomes (P < 0.05) and was associated with mortality (P < 0.05). Mortality was also associated with methicillin-resistant S. aureus infection (P < 0.05). Of those with follow up longer than 1 year, retinal detachment developed in 3 of 10 eyes (30%) after the acute infection, and cataract developed in 6 of 9 (67%) phakic eyes. Mean follow up was 146 (4-313) weeks. CONCLUSIONS: Intravitreal antibiotics for endogenous bacterial endophthalmitis administered within 24 h to supplement immediate systemic antibiotics may provide a relatively favourable visual prognosis.
