Methods: A retrospective review of the electronic medical records of 114 patients between January 2008 and December 2019 was carried out. All patients were diagnosed with clinical endophthalmitis, treated with Endophthalmitis Vitrectomy Study first intravitreal injection, and then undergone pars plana vitrectomy with intraocular antibiotics.

Results: 61/114(53.5%) patients had non-traumatic postoperative (PO) and 53/114 (46.3%) had posttraumatic (PT) endophthalmitis. Males were predominant in all types of endophthalmitis. Significantly younger individuals constituted the PT group. Best-corrected visual acuity (BCVA) at presentation was <1/60 in the majority (94.2%) of patients, while the treatment outcome was variable in the etiology with respect to BCVA that improved to 6/60 in 27 (23.68%) eyes and >6/24 in 17 (15.7%) eyes. In addition, 23 (20.2%) did not have any perception of light, and no significant change was detected in the visual outcome (p=0.278) according to etiologies.

Conclusion: Infectious endophthalmitis is a rare but serious sight-threatening complication. Aggressive and prompt treatment causes significant improvement in vision. Etiology does not have a significant impact on the outcome of EVS in PT cases. Keywords : endophthalmitis, etiology, postsurgical, posttraumatic
