目的：分别观察显微镜下最小量外路手术与传统外路手术治疗非复杂性孔源性视网膜脱离的疗效，并进行分析比较。

方法：回顾性分析我院53例53眼非复杂性孔源性视网膜脱离者临床资料，其中25例25眼采用显微镜下最小量外路视网膜脱离手术(研究组)，28例28眼采用传统外路视网膜脱离手术(对照组)，所有手术均由同一手术医生完成，对两组的临床疗效及并发症情况进行对比分析。

结果：两组术后裂孔封闭情况、一次视网膜复位率差异均无统计学意义(P>0.05)，两组术后并发症差异有统计学意义(P<0.05)，两组术后最佳矫正视力均比术前提高，两组之间术后视力提高差异无明显统计学意义(P>0.05)，两组手术时间差异有统计学意义(P<0.01)。

结论：显微镜下最小量视网膜外路手术与传统外路视网膜手术在治疗非复杂性孔源性视网膜脱离的疗效接近，但最小量外路手术时间短、损伤小、并发症少。

METHODS:The clinical data of 53 patients with 53 eyes of non-complicated rhegmatogenous retinal detachment in our hospital was analyzed retrospectively, of which the minimally external retinal detachment surgery under microscopy was performed in 25 patients with 25 eyes of non-complicated rhegmatogenous retinal detachment(the research group), and the traditional external retinal detachment surgery was performed in 28 patients with 28 eyes of non-complicated rhegmatogenous retinal detachment(the control group). All surgeries were performed by the same surgeon, and the clinical efficacy and complications of the two groups were compared and analyzed.

RESULTS: In postoperative hole closure, there was no significant difference in the primary rate of reattachment of the retina between the two groups(P>0.05). There was a statistically significant difference in postoperative complications between the two groups(P<0.05). The best corrected visual acuity after surgery was better than that before surgery in both groups. There was no significant difference in the increase of postoperative visual acuity between the two groups(P>0.05). There was a statistically significant difference in operative time between the two groups(P<0.05).

CONCLUSION: The effect of minimally external retinal surgery under microscopy and traditional external retinal surgery is similar in the treatment of non-complicated rhegmatogenous retinal detachment, but the minimally external retinal surgery has the advantages of shorter time, less damage and fewer complications.
