Endophthalmitis, Visual Outcomes, and Management Strategies in Eyes with Intraocular Foreign Bodies.

Abstract

PurposeOcular trauma with intraocular foreign body (IOFB) can have devastating visual consequences. Management and antimicrobial strategies remain variable due to the infrequency and heterogeneity of presentation. Our goal was to identify risk factors for endophthalmitis and poor visual outcomes in cases of IOFB and investigate management strategies.Patients and MethodsA retrospective chart review was conducted in 88 eyes of 88 patients suffering traumatic injury with IOFB at the University of Michigan between January 2000 and December 2019. Medical records were reviewed to characterize the injuries and IOFBs as well as how clinical presentation and treatment modalities were associated with outcomes.ResultsDelayed presentation (P=0.016) and organic IOFB (P=0.044) were associated with development of endophthalmitis. Retinal detachment (P=0.012), wound length greater than 5 mm (P=0.041), and poor presenting visual acuity (P=0.003) correlated with poor final visual outcome. Antibiotic prophylaxis was given to all patients, though agents and routes of delivery varied. Endophthalmitis developed in 4.9% of the eyes after initial management, with primary and secondary removal of posterior segment IOFBs associated with similar rates of endophthalmitis (P=1.000).ConclusionPoor presenting visual acuity and severity of injury, as measured by large wound and retinal detachment, correlate with poor visual outcome. Prompt globe closure and antimicrobial prophylaxis are critical for infection prevention. In cases where IOFB removal and globe closure cannot be performed concurrently, primary globe closure with aggressive antibiotic prophylaxis offers a reasonable alternative to prevent endophthalmitis.
