During the last two years, 79 consecutive patients (i.e. eyes) with rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy (PVR), stages B and CP according to the classification of Machemer and associates, were treated. Conventional retinal surgery (scleral buckling) was used. Retina was successfully reattached in 54 (68.4%) eyes in the early postoperative period. Thirty-five (81.4%) out of 43 patients with PVR detachment stage B, and 19 (52.8%) out of 36 patients with PVR detachment stage CP achieved total retinal attachment. The difference was statistically significant (p = 0.006). In stage CP, larger areas of retinal involvement by fixed retinal folds are inversely related to the rate of anatomical success. A higher degree of preoperative PVR means less success of conventional retinal detachment surgery, so it is advised to apply a conventional surgical technique up to CP-6 stage of PVR, whereas in more advanced stages of PVR pars plana vitrectomy is needed.
在过去两年中，对79例连续性孔源性视网膜脱离（RRD）合并增生性玻璃体视网膜病变（PVR，根据Machemer及其同事的分类为B级和CP级）患者（即患眼）进行了治疗。采用了传统的视网膜手术（巩膜扣带术）。术后早期，54只（68.4%）患眼的视网膜成功复位。43例B级PVR脱离患者中有35例（81.4%）、36例CP级PVR脱离患者中有19例（52.8%）实现了视网膜完全复位。差异具有统计学意义（p = 0.006）。在CP级，固定视网膜皱褶累及的视网膜面积越大，解剖复位成功率越低。术前PVR程度越高，传统视网膜脱离手术的成功率越低，因此建议在PVR的CP-6级之前应用传统手术技术，而在PVR的更晚期阶段则需要进行玻璃体切割术。
