To observe the efficacy and safety of pars plana vitrectomy (PPV) combined with filtered air tamponade in the treatment of rhegmatogenous retinal detachment (RRD) with inferior retinal breaks.
This retrospective study included 20 patients (20 eyes) with inferior retinal breaks in RRD; all underwent PPV combined with filtered air tamponade. Preoperative examinations included BCVA, IOP, anterior segment, fundus and locations, numbers, and sizes of retinal breaks and ocular B-mode ultrasonography. Postoperative examinations included BCVA, IOP, residual gas volume, retinal reattachment, and complications.
After follow-up for 1 year, the primary retinal reattachment rate was 95% and the final reattachment rate was 100%. Pre- and postoperative BCVA averaged 1.51 ± 0.63 and 0.97 ± 0.58 logMAR, respectively; the difference was statistically significant ( < 0.001). Average pre- and postoperative IOP were not statistically different. The average volume of residual gas on the first day after the surgery was 77.5%; the gas was absorbed in all patients within 2 weeks; no significant postoperative complications were observed.
PPV combined with filtered air tamponade is a safe and effective treatment for RRD with inferior retinal breaks. Notably, the retinal reattachment rate is high, gas absorption is rapid, and incidence of complications is low.
观察玻璃体切除术（PPV）联合过滤空气填塞治疗伴有下方视网膜裂孔的孔源性视网膜脱离（RRD）的疗效和安全性。
这项回顾性研究纳入了20例（20只眼）伴有下方视网膜裂孔的RRD患者；所有患者均接受了PPV联合过滤空气填塞治疗。术前检查包括最佳矫正视力（BCVA）、眼压（IOP）、眼前节、眼底以及视网膜裂孔的位置、数量和大小，还有眼部B超检查。术后检查包括BCVA、IOP、残余气体量、视网膜复位情况及并发症。
随访1年后，原发性视网膜复位率为95%，最终复位率为100%。术前和术后BCVA平均分别为1.51±0.63和0.97±0.58 logMAR；差异具有统计学意义（<0.001）。术前和术后平均IOP无统计学差异。术后第一天残余气体平均量为77.5%；所有患者的气体在2周内吸收；未观察到明显的术后并发症。
PPV联合过滤空气填塞是治疗伴有下方视网膜裂孔的RRD的一种安全有效的方法。值得注意的是，视网膜复位率高，气体吸收快，并发症发生率低。
