【摘要】 目的　探讨前部增生性玻璃体视网膜病变 (aPVR)的易发因素 ,发病特点和手术效果。方法　回顾性观察 164 7例增生性玻璃体视网膜病变 ,分析其中aPVR的发生情况。结果　单纯发生于赤道部以前的PVR共 63例 ,儿童较成人多发。眼球穿孔伤所致aPVR较非外伤原因多见。曾行外伤性白内障手术者aPVR明显多发。aPVR一次手术成功率 76 19% ,复发者均为儿童 ,平均复发时间为术后 6 2月。结论　儿童、眼球穿孔伤和伤后眼前段手术是aPVR的易发因素。aPVR复发周期长 ,须长期随访。更多还原

【Abstract】 Objective To investigate the etiological character and surgical results of anterior proliferative vitreoretinopathy (aPVR). Methods Study 1647 retinal detachment patients retrospectively and analyze the etiological character and surgical results of aPVR.Results There are 63 aPVR patients totally.Childern are more involved than adults.Ocular penetrating injury is the most common factor that can leads into aPVR,in which most of the patients had received traumatic cataract surgery.The percent of retinal reattachment after one vitreoretinal surgery is 76.19%.23.81% of the patients have reocurrent disease 6.2 months after the first operation and all of them are childern.Conclusion Children,penetrating injury and ocular anterior segment surgery are the most common risk factors for aPVR.The reocurrence period of aPVR is relatively long and patients should be followed-up for a long time.更多还原
