方法：选择2010-01/2012-09在我院治疗的陈旧性视网膜脱离患者134例134眼为研究对象，所有患者均为单眼视网膜脱离，其中66例患者脱离未超过6mo，68例患者脱离超过6mo，给予巩膜扣带术治疗方法，比较术后视力恢复情况。

结果：术后视力0.1以上者61例(45.5%)，明显高于术前； 视网膜脱离时间<6mo的患者术后60例(90.9%)视力提高，57例(86.4%)手术成功，均明显高于视网膜脱离时间>6mo的患者，以上差异均有统计学差异(P<0.05)。

结论：巩膜扣带术是治疗陈旧性视网膜脱离简单有效的方法，可获得较高的治愈率，同时治疗时间越早，效果越好。

METHODS: We selected 134 cases old retinal detachment patients as the objects in our hospital in recent years, all the patients was monocular retinal detachment. 66 cases of them were less than six months, 68 cases of them were more than six months, they were given scleral buckling surgery and the vision rehabilitation was compared after surgery.

RESULTS: Totally 61 cases(45.5%)of the patients' postoperative visual acuity was above 0.1, it was significantly higher than before the surgery; for the patients with retinal detachment less than half a year, 90.9% visual acuity was increased, 86.4% of the surgeries was success, they were significantly higher than the patients with retinal detachment more than six months. These differences were statistically significant(P<0.05).

CONCLUSION: Scleral buckling is a simple and effective method for the treatment of old retinal detachment. It can achieve higher cure rates and given the treatment earlier, the curative effect would be better.
