          Abstract

          Background: Proliferative diabetic retinopathy (PDR) is one of the most common cause of vision loss in diabetic patients, and the incidence age of PDR patients gradually gets younger. This study aims to compare the characteristics of PDR and outcomes following vitrectomy in young and senior patients. Methods: This is a retrospective case series study. Data of 116 eyes of 92 patients who underwent vitrectomy for PDR from February 2012 to February 2017 were reviewed, which were divided into young and senior patient groups. All patients were followed up for 24 months at least. Results: There were 62.1% of eyes with tractional retinal detachment secondary to PDR in the young patient group, while only 12.1% of eyes in the senior patient group with this surgery indication. ( P < 0.001) The best corrected visual acuity increased in 41 eyes (70.7%), stable in 9 eyes (15.5%), and decreased in 8 eyes (13.8%) in young patients at the final follow-up. And it increased in 47 eyes (81.0%), stable in 2 eyes (3.4%), and decreased in 9 eyes (15.5%) in senior patients ( P = 0.085). Postoperative complications mainly included recurrent vitreous hemorrhage (24.1%), retinal detachment (3.4%), neovascular glaucoma (NVG) (27.6%) and nuclear sclerosis (53.4%) in young patients, and it was 19.0, 0.0, 1.7 and 3.4% in senior patients respectively. Summary: PDR of young patients is more severe than that of senior patients, and vitrectomy is an effective and safe method for PDR treatment. NVG is a main and severe complication besides nuclear sclerosis in young patients, and the incidence of NVG is higher compared to that in senior patients.

          Neovascular glaucoma after vitrectomy in patients with proliferative diabetic retinopathy

          Abstract To evaluate the prevalence and risk factors of neovascular glaucoma (NVG) after vitrectomy in patients with vitreous hemorrhage associated with proliferative diabetic retinopathy (PDR). This retrospective, noncomparative, observational study included 127 eyes of 127 patients with PDR who received vitrectomy with a follow-up period of at least 6 months. The prevalence of NVG and associated risk factors were assessed including sex, age, previous panretinal photocoagulation, baseline intraocular pressure, combined phacovitrectomy, and pretreatment with intravitreal bevacizumab (IVB) before vitrectomy for the treatment of vitreous hemorrhage. NVG developed in 15 (11.8%) of 127 patients. Of the 15 eyes with NVG, 11 cases (73.3%) postoperatively developed NVG within 6 months. Postoperative NVG was associated with preoperative IVB treatment (odds ratio, 4.43; P = 0.019). The prevalence of NVG after vitrectomy was 11.8%, and an associated risk factor for NVG was preoperative IVB for the treatment of vitreous hemorrhage.

            Incidence of rhegmatogenous retinal detachment after vitrectomy in eyes of diabetic patients.

            To assess the incidence of rhegmatogenous retinal detachment (RRD) after pars plana vitrectomy (PPV) among diabetic patients with complications of proliferative diabetic retinopathy. Ninety-three eyes of diabetic patients-who underwent PPV with or without intraocular gas tamponade for complications of proliferative diabetic retinopathy-were reviewed retrospectively. Indication for vitrectomy was vitreous hemorrhage in 80 patients (86.1%), tractional retinal detachment in 3 (3.2%), and vitreous hemorrhage associated with tractional retinal detachment in 10 (10.7%). Four (4.3%) of 93 eyes developed an RRD after vitrectomy. The primary reason for vitrectomy was recurrent or nonresolving vitreous hemorrhage. The retina was attached with one additional surgical procedure in two of these eyes; the other two had to undergo a third operation before attachment was achieved. RRD occurs in a small percentage of patients after PPV with or without gas tamponade for vitreous hemorrhage or tractional retinal detachment caused by proliferative diabetic retinopathy. Thorough postoperative follow-up is important to make early diagnosis and intervention possible.
