Endogenous Endophthalmitis at a Tertiary Referral Center in China: A Retrospective Study Over Three Decades.

ABSTRACT

PURPOSE: To investigate the etiology, pathogens, treatment, and prognosis of endogenous endophthalmitis (EE). METHODS: Patients diagnosed with EE over three decades at Peking Union Medical College Hospital were retrospectively reviewed and analyzed. RESULTS: A total of 97 eyes from 81 patients were included. Diabetes was the most common predisposing medical condition (34.6%). Klebsiella pneumoniae (31.3%) and Candida albicans (32.8%) were the most common pathogens. Liver abscess (20.6%) was the predominant cause EE due to liver abscess had a worse initial visual acuity (P < 0.05). Patients who initially underwent pars plana vitrectomy (PPV)+silicone oil tamponade underwent fewer total treatments (P < 0.05). In the past 10 years, the proportion of Gram-positive cocci, Gram-negative bacilli, and Candida showed an upward trend. Over the past 15 years, EE after liver abscess and immunosuppression has increased, while EE from genitourinary systems has decreased. CONCLUSION: EE was a devastating intraocular disease with a poor visual prognosis. The initial condition and prognosis of EE after liver abscess were the worst. PPV+silicone oil tamponade as an initial treatment may reduce additional therapy.
