Abstract：
Purpose The purpose of this study is to retrospectively analyze single-operation success (SOS) rates of pneumatic retinopexy (PR) for the treatment of rhegmatogenous retinal detachment (RRD) and to identify the predictors of treatment outcomes. Methods Sixty-one eyes of 61 patients who underwent PR for RRD during a period of 12 years were included in this study. Patient demographics along with pre-treatment clinical characteristics were recorded. Treatment outcomes in terms of best-corrected visual acuity (BCVA) and anatomical characteristics were reported including any post-operative complications. Visual outcomes were compared according to pre-treatment characteristics and between groups of the eyes achieving SOS and those requiring additional surgery. Results SOS was achieved in 37 (61%) eyes. Twenty-four (39%) eyes required one (36%) or two (3%) additional procedures. There was no significant association between pre-treatment characteristics and treatment failure. SOS eyes had significantly better visual outcomes (P=0.002), and so did those with macula-on status (P=0.003). New/missed breaks (9.8%) and proliferative vitreoretinopathy (PVR) (4.9%) were the most common causes of failure. Conclusions We found PR to be a beneficial technique for the treatment of RRD in this cohort. PR remains the least invasive treatment modality, and as a cost-effective technique, it is especially useful in low/middle-income countries such as Pakistan.
摘要：
目的本研究的目的是回顾性分析用于治疗孔源性视网膜脱离（RRD）的充气视网膜固定术（PR）的单次手术成功率（SOS），并确定治疗结果的预测因素。方法对61例因RRD而接受PR治疗的患者进行了为期12年的研究。记录患者的人口统计学特征以及治疗前的临床特征。报告了最佳矫正视力（BCVA）和解剖学特征方面的治疗结果，包括任何术后并发症。根据治疗前的特征以及实现SOS的眼睛组和需要额外手术的眼睛组之间的视觉结果进行比较。结果37只(61%)眼达到SOS。二十四只(39%)眼需要一个(36%)或两个(3%)额外手术。治疗前特征与治疗失败之间没有显着关联。SOS眼的视觉结果明显更好（P=0.002），黄斑开启状态的患者也是如此（P=0.003）。新的/错过的中断（9.8％）和增生性玻璃体视网膜病变（PVR）（4.9％）是失败的最常见原因。结论我们发现PR是该队列中治疗RRD的有益技术。PR仍然是侵入性最小的治疗方式，作为一种经济有效的技术，它在巴基斯坦等低收入/中等收入国家特别有用。
