方法：我院眼底外科收治的单纯性视网膜脱离患者100例106眼，随机分为观察组和对照组，每组各53眼。观察组采用巩膜外加压术治疗，对照组沿用传统角膜缘球结膜切口术治疗。术后随访观察6～18mo，观察两组术后眼底视网膜复位情况、视力提高程度、术后并发症发生率。

结果：观察组和对照组一次复位成功率分别为96.22%和88.68%，差异有统计学意义(P<0.05)，观察组显著高于对照组； 观察组和对照组术后视力提高45眼和38眼，分别占84.90%和71.70%，差异有统计学意义(P<0.05)，观察组显著高于对照组； 观察组和对照组术后分别有6眼和17眼发生并发症，分别占11.32%和32.08%，差异有统计学意义(P<0.05)，观察组显著低于对照组。

结论：改良式微创小切口巩膜外加压手术可显著提高单纯性视网膜疗效，降低并发症的发生，显著改善视功能，为孔源性视网膜脱离患者的治疗提供又一新的科学、严谨、实用的治疗方法。

METHODS:Totally, 100 cases of patients with retinal detachment(106 eyes)enrolled in our hospital were randomly divided into observation group and control group, 53 eyes in each group. Patients in observation group were treated with minimally invasive sclera buckling, while patients in control group received traditional limbal conjunctival incision. After surgery, patients were all followed up for 6～18mo, during which the retinal recurrence situation, degree of vision enhancement and compliance occurrence rate was recorded.

RESULTS: The retinal reattachment rate once of observation group(96.22%)was significantly higher than that of control group(88.68%), there was statistically significance(P<0.05). The vision enhancement rate of observation group(84.90%)was significantly higher than that of control group(71.70%), there was statistically significance(P<0.05). The compliance occurrence rate of observation group(11.32%)was significantly lower than that of control group(32.08%), there was statistically significance(P<0.05).

CONCLUSION: The improved minimally invasive sclera buckling can significantly enhance the curative effect for retinal detachment, decrease the compliance occurrence rate, improve vision function, and is a scientific, practical and rigorous tool for retinal detachment treatment.
