Effects of vitrectomy with preoperative intravitreal Conbercept for proliferative diabetic retinopathy

Abstract

AIM: To analyze the clinical effects of preoperative intravitreal Conbercept combined vitrectomy for proliferative diabetic retinopathy(PDR)patients. METHODS: From June 2014 to May 2017, 57 patients(65 eyes)diagnosed with PDR. The patients were divided into two groups according to whether received preoperative intravitreal conbercept: intravitreal group(27 cases, 31 eyes), control group(30 cases, 34 eyes). Intravitreal group was treated with 0.05mg(0.05mL)conbercept intravitreal injection 3d before vitrectomy, while control group was treated with vitrectomy alone. The overall surgical time, intraoperative bleeding, use of endodiathermy, iatrogenic retinal hole, and silicone oil, postoperative vitreous hemorrhage and the best corrected visual acuity were recorded and analyzed. RESULTS: The average surgical time of intravitreal group was lower(PPPCONCLUSION: Intravitreal conbercept for proliferative diabetic retinopathy before 25G vitrectomy decreased surgical complications, reduced the surgical time and postoperative vitreous hemorrhage, and improved the potoperative best corrected visual acuity.
