This prospective study examines the effectiveness of the pneumatic buckle procedure (nondrainage scleral buckle with pneumatic retinopexy) for repair of primary rhegmatogenous retinal detachments.
We studied 58 consecutive patients with primary rhegmatogenous retinal detachments who underwent a pneumatic buckle with air or SF6. The procedures were performed at 2 centers. Retinal reattachment and visual acuity were examined.
The single operation reattachment rate for patients undergoing a pneumatic buckle procedure was 95%. Eighty eight percent of patients with macula-on detachment had unchanged or improved final visual acuity. Sixty seven percent of patients with macula-off detachments had a final visual acuity between 20/20 and 20/50. Twenty nine percent had final visual acuity between 20/60 and 20/200. Two patients developed a new retinal hole postoperatively.
Pneumatic buckle is an effective technique for repair of primary rhegmatogenous retinal detachments caused by breaks in the superior 8 o'clock segment. This technique avoids the complications associated with the drainage portion of the traditional scleral buckle operation and results in a high rate of retinal reattachment and stable or improved visual acuity. The rate of new retinal hole formation in this study is much lower than those reported for pneumatic retinopexy.
本前瞻性研究探讨气体扣带术（不引流巩膜扣带联合气体视网膜固定术）修复原发性孔源性视网膜脱离的有效性。
我们研究了58例连续接受气体（空气或SF6）扣带术的原发性孔源性视网膜脱离患者。手术在2个中心进行。检查视网膜复位情况和视力。
接受气体扣带术患者的单次手术复位率为95%。黄斑在位脱离患者中，88%的患者最终视力无变化或提高。黄斑不在位脱离患者中，67%的患者最终视力在20/20至20/50之间。29%的患者最终视力在20/60至20/200之间。2例患者术后出现新的视网膜裂孔。
气体扣带术是修复由上方8点方位裂孔引起的原发性孔源性视网膜脱离的有效技术。该技术避免了传统巩膜扣带术引流部分相关的并发症，导致视网膜复位率高且视力稳定或提高。本研究中新视网膜裂孔形成率远低于气体视网膜固定术的报道。
