Endophthalmitis after Cataract Surgery: Changes in Management Based on Microbiologic Cultures

Area of Science:

• Ophthalmology
• Infectious Diseases
• Microbiology

Background:

• Post-cataract surgery endophthalmitis is a serious complication.
• Microbiologic culture data is often used to guide treatment decisions.

Purpose of the Study:

• To evaluate the clinical utility of microbiologic vitreous culture results in managing endophthalmitis following cataract surgery.

Main Methods:

• A retrospective, single-center cohort study analyzed 111 eyes with post-cataract surgery endophthalmitis.
• Clinical management changes (intravitreal antibiotics, vitrectomy) within two weeks of initial treatment were assessed.
• Visual acuity and rates of retinal detachment were recorded.

Main Results:

• 51% of cases were culture-positive. Microbiologic cultures had limited impact on clinical management, with no additional interventions based solely on positive results.
• Culture-positive eyes showed significantly worse final visual acuity (logMAR 1.09 vs. 0.59) and higher rates of secondary rhegmatogenous retinal detachment (19% vs. 6%).

Conclusions:

• Vitreous cultures after endophthalmitis may offer prognostic value for visual outcomes.
• However, culture results demonstrated a limited effect on immediate clinical management decisions in this cohort.
