To evaluate the visual outcome associated with intravitreal antibiotics (IVA) and pars plana vitrectomy (PPV) for acute postprocedure endophthalmitis.

Data from 237 eyes presenting with acute postprocedure endophthalmitis were collected from 57 retina specialists in 28 countries. All eyes were treated with IVA on the day of presentation. We classified eyes according to the method of treatment used as IVA and early PPV (IVA + PPV within 1 week of presentation) groups.

After exclusion of ineligible eyes, data from 204 eyes were analyzed. The mean (SD) age of patients was 62.7 (21.8) years and 69.3 (12.7) years in the IVA and PPV groups, respectively (P = 0.18). Endophthalmitis secondary to cataract, intravitreal injections, PPV, and other intraocular procedures represented 64.2%, 16.2%, 13.7%, and 5.9% of cases, respectively. Intravitreal antibiotics alone were administered in 55 eyes (27.0%), and early PPV was performed in 149 eyes (73.0%). No difference was found between groups in the final visual acuity of ≥20/60 (43.6%, 65 eyes vs. 34.5%, 19 eyes) and ≤counting fingers (30.9%, 46 eyes vs. 36.4%, 20 eyes) for IVA versus early PPV groups, respectively. Vision of light perception (odds ratio = 12.2; 95% confidence interval: 2.0-72.6) and retinal detachment (odds ratio = 7.7; 95% confidence interval: 1.5-409) at baseline were predictive of vision of ≤counting fingers. Retinal detachment at baseline (odds ratio = 20.4; 95% confidence interval: 1.1-372.1) was predictive of final retinal detachment status.

The current retrospective multicenter cohort of eyes with acute postprocedure endophthalmitis reports similar outcomes after treatment with IVA alone when compared with IVA and early PPV within 1 week of presentation.
