ABSTRACT

Purpose:

Exogenous endophthalmitis (EE) is the most serious complication of penetrating eye surgeries and open globe trauma (OGT). It is crucial to know the associated factors that will determine the final visual prognosis. The aim of the present study was to describe the epidemiological, clinical profile and visual outcomes (VO) predictors in patients with EE in a referral ophthalmology center.

Methods:

Retrospective, observational clinical study. Patients diagnosed with EE between January 2018 to September 2021 were included. Data collected included demographic characteristics, endophthalmitis origin, culture samples, microbiological diagnosis, initial and final best corrected visual acuity (BCVA), and treatment received. Major outcome was change in BCVA after endophthalmitis treatment and associated factors. T-test and Fisher's exact test for statistical analysis were used.

Results:

Seventy-three patients with EE were included. Surgery associated (SA) was the most common cause responsible for 39 cases (53.4%), followed by keratitis associated 18 cases (24.6%) and trauma associated (TA) 16 cases (21.9%). Gram-positive bacteria predominated in positive cultures (n= 35 [54.3%]). There was a statistically significant difference at mean age between TA group 41.1 ±18.7 years and SA group 59.9 ±20.9 years (p= 0.002). Final logMAR BCVA in the TA group was 4 ±0.9 (Snellen, light perception [LP]) and in the SA group was 2.7 ±1.7 (Snellen, Hand Motion [HM]). Fourteen (35.8%) patients in the SA group had a final BCVA ≥ 20/400;whereas in the TA group all patients had a final BCVA ≤ CF. Risk factors for non-improving BCVA after EE included OGT (p= 0.007) and initial BCVA of LP or worse (p <0.0001) in the SA group. There was no statistical difference in the final VO in patients that were treated with intravitreal injection (II) and those treated with vitrectomy (VTM) (p =0.40). Although 6 patients (75%) treated with VTM had an improvement in final BCVA compared with 12 (57.1%) of the patients just treated with II, this could be due to the sample number. We observed a tendency of diminishing cases of TA endophthalmitis after covid era, this could be associated with the isolation measures recommended.

Conclusions:

Surgery associated EE had a better visual prognosis than those with trauma associated EE. The initial BCVA is a meaningful indicator for final VO, being favorable when is better than HM.
