To study the practice patterns for the management of acute postoperative and postinjection endophthalmitis.

Retrospective, interventional, nonrandomized, multicenter study.

Data on 237 eyes diagnosed with acute endophthalmitis occurring after intraocular surgery or procedures provided by 57 retina specialists from 28 countries.

Rates of pars plana vitrectomy (PPV), repeat intravitreal injection, and adjunctive therapeutic regimens (local and systemic antibiotics and steroids).

Of 237 analyzed eyes, acute endophthalmitis secondary to cataract surgery or secondary lens implantation represented 64.6% of cases (153 eyes), whereas the remaining were secondary to intravitreal injections (35 eyes [14.8%]), PPV (29 eyes [12.2%]), and other intraocular surgeries (20 eyes [8.4%]). All eyes received intravitreal antibiotics on the same day of diagnosis. Overall, early PPV was used within the first week of presentation in 176 eyes (74.3%). There was no statistical difference in the proportion of eyes requiring a second intravitreal injection of antibiotics whether the eye was managed primarily with intravitreal antibiotics alone versus early PPV plus intravitreal antibiotics (29.5% [18 eyes] vs. 25.0% [44 eyes], respectively). Adjunctive therapies in the form of intravitreal steroids, systemic steroids, and systemic antibiotics were used in 25.3%, 21.9%, and 66.6% of eyes, respectively. The absence of disc or macular view and absence of endophthalmitis after cataract surgery were associated with an increased likelihood for early PPV (odds ratios 4.1 and 5.1, respectively).

Pars plana vitrectomy was frequently performed regardless of the presenting vision in eyes with endophthalmitis after cataract surgery and intravitreal injections. Increased vitreous opacification was associated with a higher probability for performing PPV.
