为探讨玻璃体切除术的治疗效果及其相关因素，对34例玻璃体切除术进行了回顾性研究，对不同病情联合白内障摘出、或联合后房人工晶状体植入、异物搞出术。近期和远期治愈率分别为70．8％和30.6％。白内障治愈率为50％，作者认为玻璃体切除术是治疗玻璃体视网膜病变的有效方法；术前全面检查对手术并发症的处理及手术成败非常重要。 In order to explore the therapeutic effect of vitrectomy and its related factors, 34 cases of vitrectomy were retrospectively studied. Different conditions combined with cataract extraction or combined posterior chamber intraocular lens implantation were performed. Short-term and long-term cure rates were 70.8% and 30.6% respectively. The cure rate of cataract is 50%, the authors believe that vitrectomy is an effective method of treatment of vitreoretinopathy; preoperative comprehensive examination of the surgical complications and surgical success or failure is very important.
