Abstract:

Objective   To analyze the risk factors of blindness after vitreoretinal surgery for proliferative diabetic retinopathy (PDR)． Methods   A total of 142 eyes of 110 patients undergoing vitrectomy for PDR were followed up. Results   In the 142 eyes with diabetic blindness， 91(64.1%) were improved in visual acuity and postoperative blindness occured in 51(35.9%) . The chief causes of blindness were traction retinal detachment, severe retinal vascular occlusion, optic neuropathy, diffuse macular edema and neovascular glaucoma. Conclusion   The incidence of blindness after vitreoretinal surgery for PDR is high, and early prevention and treatment is important to avoid diabetic blindness.

Key words: Diabetic retinopathy； Vitrectomy； Blindness
