Endoscopic Pars Plana Vitrectomy in Patients With Open-Globe Injury and Corneal Opacity

Purpose: To determine the 1-year outcomes of endoscopic pars plana vitrectomy (EPPV) and its impact on the corneal transplantation rate in patients with open-globe injury (OGI) and corneal opacity. Methods: This retrospective cohort study collected data between December 2018 and August 2021. All EPPVs were performed at a level I trauma center. Inclusion criteria were adult patients with a history of OGI complicated by corneal opacification that prevented fundus visualization. The main outcome measures were the rate of successful retinal reattachment, final visual acuity (VA), and number of patients who had penetrating keratoplasty (PKP) within 1 year of the OGI. Results: Ten patients (3 women; 7 men) with a mean age of 63.4 ± 22.7 years (SD) met the inclusion criteria. The indications for EPPV were intraocular foreign bodies in 2 patients, dense vitreous hemorrhage in 3 patients (1 with a retinal tear; 1 with a choroidal hemorrhage), and retinal detachment in 5 patients. The final VA ranged from 20/40 to no light perception. All 4 repaired detachments remained attached after 1 year. Corneal opacity was treated with PKP in 3 patients. Conclusions: Results indicate EPPV can be a useful tool to treat posterior segment pathology in patients with a recent OGI and corneal opacity. EPPV can help address posterior segment disease and postpone corneal transplantation until the visual potential can be fully determined. Larger prospective studies are needed.
