摘要
目的 探讨晶状体手术对增生型糖尿病视网膜病变(PDR)患者玻璃体切割术后虹膜新生血管(INV)形成的影响。方法 总结行玻璃体切割手术的182例病例(198只眼),采用卡方检验对数据进行统计学分析。结果 在198只眼中有23只眼(约116%)发生INV,其中无晶状体后囊(PC)缺失或后囊不完整14只眼(占609%)。PC缺失或不完整与PC完整比较INV形成有显著性差异(χ2=721,P<001),晶状体手术后后囊完整与有晶状体比较INV形成无显著性差异(χ2=0006,P>090)。结论 PC缺失或不完整可能是PDR患者玻璃体切割术后INV形成的重要原因,糖尿病患者手术时应保留晶状体PC的完整性。
ObjectiveTo investigate the effect of lens surgery on iris neovascularization(INV) in patients with proliferative diabetic retinopathy(PDR) after vitrectomy.Methods182 patients(198 eyes) with PDR undergone vitrectomy from 1988 to 1997 in our hospital were reviewed.The data were analysed through chi square test.ResultsINV occurred in 23 eyes (11.6%) of 198 eyes.Of those eyes with INV,60 9% were without posterior capsule(PC) or with ruptured PC.There was significant difference between eyes with lacking or ruptured PC and eyes with intact PC( χ 2=7 21, P <0 01).No difference was found between postoperative eyes with intact PC and eyes without lens surgery( χ 2=0 006, P >0 90).ConclusionPC lacking or ruptured may be the significant factor causing iris neovascularization in patients after vitrectomy for PDR.Thus,PC should be kept intact in lens surgery for diabetic patients if possible.
