Abstract
Purpose:
This work describes the characteristics, treatment, and outcomes of endogenous endophthalmitis (EE) cases over 13 years at a tertiary care hospital.
Methods:
This retrospective case series included EE cases from 2006 to 2018. Eyes were categorized by cultured organism and initial treatment status.
Results:
Forty-five eyes of 38 patients were identified with EE. Mean age was 48 ± 12 years and approximately three-fourths were male. Mean visual acuity (VA) at presentation was logMAR 1.86 ± 0.83. More than 50% of patients had a history of intravenous drug use. In a quarter of patients, no systemic source of infection was identified; 90% of these patients had a history of intravenous drug use. Bilateral infections occurred in 18% of participants. Of positive cultures, 29%, 56%, and 13% were fungal, gram-positive, and gram-negative in etiology, respectively. Eyes with fungal infections had a better presenting VA and were more likely to have better than 20/100 final VA vs those with bacterial infections. All patients received IV antibiotics; additionally 29% of eyes underwent initial combined pars plana vitrectomy with intravitreal antibiotic injection while 51% of eyes initially received bedside intravitreal antibiotic injection. There was no significant difference in final VA with respect to initial mode of treatment.
Conclusions:
Initial treatment of intravitreal antibiotics with or without pars plana vitrectomy did not show any difference in the average final VA in eyes with EE. Eyes with fungal infections had more favorable visual outcomes than those with bacterial infections. Almost 1 in 5 EE eyes were enucleated.
