Endogenous Bacterial Endophthalmitis: A Five-Year Retrospective Review at a Tertiary Care Academic Center

Abstract

ABSTRACT Purpose To better characterize the demographics and outcomes of endogenous bacterial endophthalmitis (EBE). Methods Retrospective observational case series of 49 eyes of 41 patients with EBE evaluated at a single academic center. Results Gram stain (p = .395), symptom duration prior to treatment (p = .483), and number of intravitreal antimicrobial injections (p = .421) did not correlate with mean change in VA. There was no significant difference between mean LogMAR VA at initial evaluation (1.7 ± 0.9) and last available follow up (1.4 ± 1.1, p = .15). Patients with bilateral EBE had 7.25 times greater odds of having cancer (95% CI 1.28, 41.14; p = .025). Conclusion EBE in a North American population showed poor visual recovery despite treatment. It was most commonly due to gram-positive bacteria with the most common infectious source being endocarditis. Malignancy should be considered in patients with bilateral EBE.
