原发性孔源性视网膜脱离的病例中约10％将发生增殖性玻璃体视网膜病变(PVR),它一旦发生进一步治疗困难而且效果不能肯定,部分病例终将失明。到目前为止PVR被认为是一种细胞所介导的疾病,其中视网膜脱离发生后产生的视网膜下液(SRF)中所含的某些物质刺激了PVR形成的细胞
In about 10% of cases of primary rhegmatogenous retinal detachment, proliferative vitreoretinopathy (PVR) occurs and in some cases it will eventually become blind if further treatment is difficult and the outcome is not certain. PVR has so far been considered as a cell-mediated disease in which certain substances contained in the subretinal fluid (SRF) produced after retinal detachment stimulate cells formed by PVR
