1985~1990年间，对340眼严重(C3或以上)增殖性玻璃体视网膜病变(PVR)的孔源性视网膜脱离(RRD)患者行玻璃体手术治疗，其中183眼未行玻璃体手术(组1)，157眼行玻璃体切除联合眼内气体填充术(组2)。在视力达到5/200或更高(44%比39%)、黄斑复位率(78%比77%)或完全视网膜复位率(两组均为67%)方面，两组眼之间没有差异。在第一组中，74只眼在一次手术后视网膜完全复位；另外41只眼在第二次手术后达到视网膜复位。在第2组，这两个数字分别为74和26。多次手术成功的患者视力恢复到5/200或更高的可能性低于一次手术成功的患者(P<；0.01)。两组之间在低眼压方面没有差异，但第二组的角膜病变更常见(P<；0.05)：结果表明，第一组和第二组之间的结果差异并不像之前认为的那么大。
Between 1985 and 1990, 340 eyes with rhegmatogenous retinal detachment (RRD) and severe (stage C3 or worse) proliferative vitreoretinopathy (PVR) were treated with vitrectomy and randomly selected to receive perfluoropropane gas or silicone oil; 183 eyes had undergone no prior vitrectomy (group 1), and 157 eyes had undergone prior vitrectomy with intraocular gas tamponade (group 2). No differences were found between eyes in the two groups in achieving visual acuity of 5/200 or better (44% vs. 39%), macular reattachment (78% vs. 77%), or complete retinal reattachment (67% for both groups). In group 1, 74 eyes achieved complete retinal reattachment after only one operation; 41 additional eyes achieved reattachment after a second surgical procedure. In group 2, these numbers were 74 and 26, respectively. Eyes treated successfully after more than one operation were less likely to regain a visual acuity of 5/200 or better than those successfully treated with one operation (P < 0.01). There was no difference in hypotony between groups, but keratopathy was more frequent in eyes in group 2 (P < 0.05): The results suggest that differences in outcomes between group 1 and group 2 eyes are not as great as previously believed.
