目的：观察最小量巩膜扣带术治疗陈旧性视网膜脱离的临床效果。

方法：回顾性分析2014-01/2018-09在我院行最小量巩膜扣带术的陈旧性视网膜脱离患者54例54眼的临床资料，术后随访6mo，观察视网膜复位情况和最佳矫正视力(BCVA)、眼压、眼轴、角膜散光等眼部参数情况，并根据术前视网膜脱离时间、脱离范围、是否累及黄斑和术后是否存在持续性视网膜下液(PSF)对术后BCVA改善情况进行分析。

结果：本组患者初次手术后视网膜完全复位49眼(91%)，其中29眼术后存在PSF。至末次随访时12眼(22.2%)BCVA提高，38眼(70.4%)BCVA无变化，4眼(7.4%)BCVA下降。术前视网膜脱离时间、脱离范围、是否累及黄斑和术后是否存在PSF对术后BCVA改善情况均有一定影响。

结论：最小量巩膜扣带术治疗陈旧性视网膜脱离安全有效，但是术后视力改善与诸多因素有关。

METHODS: The clinical data of 54 eyes in 54 cases of long standing retinal detachment treated by the minimal scleral buckling in our hospital during January 2014 to September 2018 were analyzed retrospective. Patients were followed up for 6mo. The rate of postoperative retinal reattachment, the best corrected visual acuity(BCVA), intraocular pressure, eye axis and astigmatism were observed. According to the preoperative time of retinal detachment, retinal detachment range, macular involvement or not and presence of PSF or not, the improvement of postoperative BCVA were analyzed.

RESULTS: The retina reattached in 49 eyes(91%)after primary operation. Postoperative persistent subretinal fluid was observed in 29 eyes of them by optical coherence tomography. At the last follow up, BCVA increased in 12 eyes(22.2%), remained unchanged in 38 eyes(70.4%), and decreased in 4 eyes(7.4%).The preoperative time of retinal detachment, retinal detachment range, macular involvement or not and presence of PSF or not had an impact on the postoperative recovery of BCVA.

CONCLUSION: The minimal sclera buckling surgery is an effective method to treat long standing retinal detachment. But postoperative visual acuity recovery is related to many factors.
