增殖性玻璃体视网膜病变(PVR),是孔源性视网膜脱离的常见并发症和手术失败的主要原因,也可发生于眼外伤和视网膜血管性疾病。以往曾认为由玻璃体的收缩引起。实践和临床研究证实,视网膜表面的细胞增生和收缩是本病的基本病理过程。这一过程在临床上表现为前部(赤道前及玻璃体基部)和后部(赤道后)的增生性膜及其造成的多种形式的收缩牵拉,以及视网膜后膜 Proliferative vitreoretinopathy (PVR), is a common complication of rhegmatogenous retinal detachment and surgical failure of the main reasons can also occur in ocular trauma and retinal vascular disease. In the past has been that caused by the contraction of the vitreous. Practice and clinical studies have confirmed that retinal cell proliferation and cell proliferation is the basic pathological process of the disease. This process is clinically manifested as anterior (pre-equator and vitreous basal) and posterior (posterior) hyperplastic membranes and their various forms of contracting traction, as well as the retro-retina
