Abstract: Objective To investigate the effectiveness and safety of retinal photocoagulation(RP) in combination with vitrectomy in treatment of proliferative diabetic retinopathy(PDR). Methods The clinical data of 79 patients (79 eyes) with PDR treated by RP and vitrectomy in our hospital during March 2010 to March 2014 were retrospectively analyzed. Results In a follow-up of 12 months after the operation, 61 eyes (77.22%) improved their post-operative visual acuity, 15 eyes (18.99%) had the same vision and 3 eyes (3.80%) had deterioration. After vitrectomy of 1 month, 2 eyes had the iop elevated over 30 mmHg, 1 eye had neovascular glaucoma (NVG), and 1 eye had retinal detachment. After vitrectomy of 3 months, 2 eyes had fro vitreous hemorrhage again. After vitrectomy of 12 months, 2 eyes had silicone oil emulsification occurred secondary glaucoma. Conclusion Angiography after vitrectomy can be targeted to treat RP. It can avoid excessive photocoagulation and can prevent photocoagulation insufficiently, improves in vision at the same time with few complications and high safety, is an effective method for PDR.
