To clarify the risk factors of proliferative vitreoretinopathy (PVR) in aphakia, the clinical features of 25 aphakic eyes with PVR were statistically analyzed and compared with a control group of 157 aphakic eyes with non-PVR rhegmatogenous retinal detachment. The statistically significant (P less than 0.05) factors that predisposed patients to PVR in aphakia were as follows: a history of vitreous loss on cataract surgery, retinal detachment developing within 3 months after cataract extraction, duration of retinal detachment longer than 3 months, break larger than three disc diameters, and choroidal detachment. Vitreous loss is believed to play the most important role in the development of PVR in aphakia.
为明确无晶状体眼增殖性玻璃体视网膜病变（PVR）的危险因素，对25只发生PVR的无晶状体眼的临床特征进行了统计学分析，并与157只发生非PVR孔源性视网膜脱离的无晶状体眼对照组进行比较。在无晶状体眼中，使患者易患PVR的具有统计学意义（P<0.05）的因素如下：白内障手术中玻璃体丢失史、白内障摘除术后3个月内发生视网膜脱离、视网膜脱离持续时间超过3个月、裂孔大于3个视盘直径以及脉络膜脱离。玻璃体丢失被认为在无晶状体眼PVR的发生中起最重要作用。
