PURPOSE: To determine the indications, findings, and outcomes of patients with open globe injury (OGI) requiring pars plana vitrectomy (PPV). DESIGN: Retrospective, single-vitreoretinal surgeon case series. PARTICIPANTS: Sixty-one consecutive eyes with OGI that required PPV. METHODS: Retrospective chart review of consecutive patients who underwent PPV after OGI between March 1, 2011, and August 1, 2017, at Massachusetts Eye and Ear by 1 surgeon. MAIN OUTCOME MEASURES: Final visual acuity and rates of recurrent retinal detachment (RD) and proliferative vitreoretinopathy (PVR). RESULTS: Sixty-one eyes of 61 consecutive patients underwent PPV after sustaining OGI. Mean follow-up was 12.8±12.1 months (range, 0.5-65 months). At the time of presentation after OGI, 64% of eyes showed light perception or worse vision. The indications for PPV, which was performed on average of 15 days after injury, included RD without retinal incarceration (39%), RD with retinal incarceration in the scleral or corneal wound or both (13%), media opacity without RD (28%), vitreous traction without RD (11%), intraocular foreign body (5%), and endophthalmitis (3%). At the time of PPV, substantial comorbidities were noted, including corneal trauma (20%), hyphema (41%), iris trauma (62%), lens expulsion (54%), subretinal hemorrhage (51%), and choroidal hemorrhage (30%). Using multivariate analysis, factors associated with RD after initial PPV were preoperative subretinal hemorrhage (odds ratio [OR], 5.73; P = 0.03), PVR found at initial PPV (OR, 11.94; P = 0.021), and retinectomy (OR, 17.88; P = 0.003). No patients were inoperable, because all patients left the operating room with complete retinal reattachment. Of 35 eyes that showed RD, 19 (54%) redetached as a result of PVR. In 80% of eyes with RD at initial presentation (28/35 eyes), the retina remained completely attached at last follow-up, and 5 additional eyes remained partially attached (33/35 [94%]). Of 61 total eyes included in this study, 89% remained completely attached, and 42 (69%) achieved visual acuity of 20/200 or better at last follow-up. CONCLUSIONS: Despite substantial ocular comorbidities, PPV can result in retinal reattachment in even the most severe cases. Good visual outcomes can be achieved for most patients who undergo vitreoretinal surgery after open globe trauma.
