Abstract:
Objective To discuss the intraoperative and postoperative effects of conbercept combined with pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR) patients.Methods From January 2016 to December 2016,123 PDR patients (149 eyes) aged 41-65 years old with nonclearing vitreous hemorrhage (VH) and/or tractional retinal detachment (TRD) were enrolled in this study.According to whether preoperative intravitreal injection conbercept,the patients were divided into two groups:Conbercept group (64 cases,78 eyes),Control group (59 cases,71 eyes).Conbercept group was treated with intravitreal injection of Conbercept 0.50 mg (0.05 mL) at 3 days before PPV.Then the standard 23G minimally invasive sclera three-channel vitrectomy was performed if no significant complications after the injection of conbercept.The operation time,intraoperative bleeding,iatrogenic retinal hole,use of endodiathermy and silicone oil,and postoperative complications were recorded and analyzed.The visual acuity and macuiar thickness were compared before and 1 month after the surgery.Results Two groups had no difference on age,sex,HbA1 C,duration,VH ≥ three degree(56/78,45/71),TRD.Conbercept pretreatment could significantly reduce the bleeding during PPV (43/78,49/71),the probability of iatrogeuic retinal holes (11/78,21/71),reduce intraocular electrocoagulation using (57/78,62/71) and silicone oil (43/78,51/71),and then shorten the operation time (58.63 ± 21.66)s and (72.69 ± 22.48)s,and it could significantly improve the postoperative visual acuity (0.23 ± 0.15,0.16 ± 0.11) and macular edema thickness (260.95 ± 27.44) μm and (330.81 ± 36.62)μm,while reduce the incidence of second bleeding (3/78,10/71).Conclusion Conbercept pre-treatment combined with PPV for PDR is a positive and effective treatment,which has good clinical application significance.
