Purpose. To evaluate visual outcomes and identify prognostic factors after pars plana vitrectomy (PPV) surgery for traumatic endophthalmitis. Methods. Medical records of 121 consecutive patients (121 eyes) diagnosed with traumatic endophthalmitis that had undergone pars plana vitrectomy were retrospectively reviewed. Results. 121 patients, aged from 6 to 71 years, all underwent PPV surgery. 113 cases had improved best corrected visual acuity (BCVA) after surgery and 60% of them obtained BCVA better than fingers counting (FC). Good final visual prognosis was significantly associated with time between trauma and initial treatment less than 12 hrs (40% versus 98%; P<0.001), time between trauma and PPV treatment less than 24 hrs (62% versus 98%; P<0.001), laceration length less than 10 mm (63% versus 96%; P<0.001), and presenting VA better than LP (42% versus 96%; P<0.001), while gender, type of laceration, presence of IOFB or retinal detachment, and the use of silicone oil tamponade were not significant factors resulting in better BCVA. Bacteria were identified in 43.8% of specimens and most of the microorganisms were identified as nonvirulent ones. Conclusions. Pars plana vitrectomy surgery was preferred as a primary treatment option for traumatic endophthalmitis. A good final visual prognosis was significantly associated with timely treatment, prompt vitrectomy surgery, shorter length of laceration, and better presenting visual acuity.

Purpose. To investigate the vascular density of the optic nerve head (ONH) and macula using optical coherence tomography angiography (OCTA) in patients undergoing vitrectomy for rhegmatogenous retinal detachment (RRD) and to evaluate associations with visual outcomes. Methods. Patients with RRD, successfully treated with a pars plana vitrectomy (PPV) and a minimum three-month follow-up were included in this study. The vessel density (VD) of the ONH and peripapillary regions, foveal avascular zone (FAZ), foveal flow density (FFD), and parafoveal flow density (PFD) were evaluated using OCTA and compared to the fellow eye. Multivariate linear regression analysis was performed to determine correlations with visual outcomes. Results. Thirty-one patients with macula-off RRD were included in the study. Compared with the fellow eyes, eyes after RRD surgery had a lower peripapillary VD ( P < 0.01 ). No significant difference in superficial and deep FFD, PFD, and FAZ area was found compared to the fellow eyes. Postoperative peripapillary VD and baseline BCVA were significantly associated with BCVA three months after PPV ( P < 0.05 ). Conclusion. Rhegmatogenous retinal detachment eyes successfully treated with PPV had lower peripapillary vessel density than fellow healthy eyes. Postoperative BCVA was related to postoperative peripapillary VD.

Abstract Background The recurrence of retinal detachment (RD) following rhegmatogenous retinal detachment (RRD) is a relatively common complication that threatens vision and needs further surgery. The purpose of this study is to investigate the risk factors and visual outcomes of recurrent RD following pars plana vitrectomy (PPV) for primary RRD.Methods This was a retrospective follow-up of 343 eyes that underwent initial PPV surgery for primary RRD. Patients were divided into a recurrence group and a reattachment group. The main outcome measures included the causative factors, visual outcomes of RD recurrence, and the perioperative factors most affecting the recurrence of RD.Results After retinal reattachment, we observed recurrence of RD after PPV for primary RRD in 42 out of 343 eyes (12.2%) during the follow-up period. Most recurrence (69%) occurred within 6 months after surgery. Univariate analysis showed that the primary risk factor significantly associated with recurrent RD was the presence of proliferative vitreoretinopathy (PVR) ≥ Grade C ( P = 0.003). Logistic regression analysis showed that a PVR ≥ Grade C (odds ration [OR]: 9.421, 95% confidence interval [CI]: 2.432 - 56.39; P =0.020) was a significant predictor for the development of recurrent RD. The recurrence of RD resulted in a significant decline in best-corrected visual acuity (BCVA) at the last follow-up visit compared with the reattachment group ( P =0.000). Eyes with PVR prior to primary surgery or at the diagnosis of re-detachment showed a worse final BCVA.Conclusions The presence of PVR ≥ Grade C was the predominant risk factor for the recurrence of RD. PVR prior to primary surgery, or at the diagnosis of re-detachment, limited the recovery of final visual acuity.

The Early Treatment Diabetic Retinopathy Study (ETDRS) was a randomized clinical trial involving nearly four thousand diabetic patients with early proliferative retinopathy, moderate to severe nonproliferative retinopathy, and/or diabetic macular edema in each eye. This paper (ETDRS report number 17) describes the baseline previtrectomy characteristics, initial treatment assignments, indications for vitrectomy, and visual outcomes in the subgroup of patients in the ETDRS who had pars plana vitrectomy (PPV). The study showed that pars plana vitrectomy could improve visual outcomes in patients with complications from proliferative diabetic retinopathy such as vitreous hemorrhage and retinal detachment. PPV continues to play an important role in the management of complications from proliferative diabetic retinopathy.
