尽管现代玻璃体切割术成功地处理了增殖型糖尿病视网膜病变 (proliferafive diabetic retinopathy,PDR)引起的各种并发症 ,挽救了不少严重 PDR患者的视力 ,但严重的PDR,由于新生血管、玻璃体积血、玻璃体内或视网膜表面的增殖机化膜收缩 ,常导致牵引性视网脱离 ,视网膜活动度差
Although modern vitrectomy successfully treats various complications caused by proliferative diabetic retinopathy (PDR) and saves vision in many patients with severe PDR, severe PDR, due to neovascular, vitreous hemorrhage , Intravitreal or retinal surface of the proliferation of machine-induced contraction of the film, often leading to traction retinal detachment, poor retinal mobility
