Pneumatic retinopexy was performed using only air in an attempt to minimize vitreous disturbance and lower the incidence of postoperative proliferative vitreoretinopathy (PVR) and premacular membranes (PMM). Retinal cryopexy or laser treatment (in 2 cases) and intravitreal injection of 0.8 cc filtered air were performed on 45 rhegmatogenous retinal detachments with superior breaks and no preoperative vitreous hemorrhage or PVR. Reattachment was achieved in 39 (86.7%) eyes. The remaining 6 eyes were secondarily treated with scleral buckle surgery, which was successful in all cases. The average length of follow-up was 17.1 +/- 8.6 months, at which time visual acuity was the same or better in 44 (97.8%) eyes. In 1 case (2.2%) PVR developed, a PMM formed in 1 case (2.2%), and new or missed retinal breaks were found in 4 cases (8.8%). This technique achieves a high rate of reattachment, good visual outcome, and low incidence of PVR, PMM, and new or missed breaks, perhaps due to the short-acting, nonexpansile nature of air.
采用单纯空气进行气体视网膜固定术，以尽量减少玻璃体扰动，降低术后增生性玻璃体视网膜病变（PVR）和黄斑前膜（PMM）的发生率。对45例伴有上方裂孔且术前无玻璃体出血或PVR的孔源性视网膜脱离患者进行了视网膜冷冻治疗或激光治疗（2例），并玻璃体腔内注射0.8 cc过滤空气。39只眼（86.7%）实现了视网膜复位。其余6只眼接受了巩膜扣带术二次治疗，所有病例均成功。平均随访时间为17.1±8.6个月，此时44只眼（97.8%）的视力相同或更好。1例（2.2%）发生PVR，1例（2.2%）形成PMM，4例（8.8%）发现新的或遗漏的视网膜裂孔。该技术可实现较高的视网膜复位率、良好的视力结果以及较低的PVR、PMM和新的或遗漏裂孔的发生率，这可能归因于空气的短效、无膨胀特性。
