继发于糖尿病视网膜病变的虹膜新生血管形成的冷凝治疗

目的:评价单纯周边视网膜冷冻治疗继发于糖尿病视网膜病变(diabetic retmopathy,DR)的虹膜新生血管形成(iris neovscularization,IN)的临床治疗效果。方法:对我院2003-01/2007-12收治的继发于DR的IN15例17眼进行回顾性分析,男11例13眼,女4例4眼;年龄34～72(平均48.6)岁。手术方法为单纯周边视网膜冷冻。观察的内容包括裂隙灯下肉眼所见的虹膜新生血管消退情况,手术前后视力和眼压(IOP)的变化。结果:裂隙灯下虹膜新生血管均消退,17眼基线视力无明显改变,眼压基本稳定。观察期为3mo。结论:周边视网膜冷冻术可有效促使继发于DR的IN的消退,方法简单安全。

Cryotherapy of iris neovascularization secondary to diabetic retinopathy

AIM:To evaluate the therapeutic effects of peripheral retinal cryotherapy for iris neovascularization (IN) secondary to diabetic retinopathy.METHODS: The authors retrospectively analyzed the clinical therapeutic outcome of 15 patients (17 eyes) with IN secondary to diabetic retinopathy. All patients were hospitalized and underwent a peripheral retinal cryotherapy from January 2003 to November 2007. The clinical trail included thirteen eyes of 11 men and four eyes of 4 women, with a mean age of 48.6 years (ranging from 34 to 72 years). The time of regression of iris new vessels, and the changes of base-line vision as well as intraocular pressures (IOP) preoperatively and postopera-tively were recorded.RESULTS: Under split lamp microscopy, completely regression of iris new vessels was observed in all 17 eyes. There was no significant change of baseline vision and IOP during the 3 months of postoperative follow-up period.CONCLUSION: Peripheral retinal cryotherapy was a simple and effective surgical procedure for IN secondary to DR, under slit lamp microscopy it can make the iris new vessels regressed completely and cheaply.
