目的：探讨单纯孔源性视网膜脱离(RRD)行微创巩膜外加压术后影响复位和视力恢复的相关因素。

方法：收集2014-12/2017-10于我院就诊的初发RRD患者296例296眼作为研究对象，所有患者行微创巩膜外加压术，观察术后视网膜复位率以及BCVA，并对可能影响视网膜复位和视力恢复的因素进行分析。

结果：首次行微创巩膜外加压术后复位成功272眼(91.9%)。围术期影响视网膜复位的因素有裂孔数、视网膜脱离范围以及C1级PVR。随访6mo时，BCVA≥0.4者 196眼(66.2%)，BCVA<0.4者 100眼(33.8%)。病程长短、术前BCVA、视网膜脱离范围、黄斑累及与否是影响术后BCVA的危险因素(均P<0.05)，术前BCVA是影响术后BCVA恢复的独立危险因素(P<0.05)。

结论：微创巩膜外加压术治疗RRD疗效确切，术后复位率较高，对于RRD患者需早发现早治疗。

METHODS: From December 2014 to October 2017, 296 cases(296 eyes)of incipient RRD patients in our hospital were selected as the research objects. All patients underwent minimally invasive scleral compression, the postoperative retinal reduction rate and BCVA were observed, and the factors that may affect the retinal reduction and visual recovery were analyzed.

RESULTS: A total of 272 eyes(91.9%)were successfully restored after minimally invasive postoperative scleral compression for the first time. Perioperative factors affecting retinal reduction include the number of holes, retinal detachment range and grade C1 PVR. At the follow-up of 6mo, 196 eyes(66.2%)had BCVA ≥0.4, and 100 eyes(33.8%)had BCVA <0.4. Duration of disease, preoperative BCVA, retinal detachment, and macular involvement were risk factors for postoperative BCVA(all P<0.05), while preoperative BCVA was an independent risk factor for postoperative BCVA recovery(P< 0.05).

CONCLUSION: Minimally invasive scleral extrascleral compression is effective in the treatment of retinal detachment due to simple aperture, with a high postoperative reduction rate. Early detection and early treatment are required for RRD patients.
