玻璃体切除术后晶体变化的临床分析

观察孔源性视网膜脱离的玻璃体切除术后晶体改变及相关因素间的关系。报告一组有晶体眼视网膜脱离手术、冷冻、巩膜扣带、注气（ＳＦ６或Ｃ３Ｆ８）联合玻璃体切除术６８例７２只眼及未联合玻璃体切除术４６例４７只眼。随访１２个月以上，比较两组，玻璃体切除眼术后发生核硬化３８．９％，非玻璃体切除眼仅５．６％，Ｐ〈０．００１。晶体后囊下混浊，玻璃体切除眼为３４％，非玻璃体切除眼仅为４．２％，Ｐ〈０．００１。核硬化与

Clinical analysis of lens changes after vitrectomy for retinal detachment

In order to assess the relationship between vitrectomy and postoperative lens changes,a series of retinal detachment operations performed in eyes with lenses were reported. Retinal detachment surgery,cryotherapy,scleral buckling,gas injection and vitrectomy were performed in 68 patients(72 eyes),and all except vitrectomy performed in 46 patients(47 eyes).According to the follow up of over 12 months after surgery,we found that the incidence of nuclear slerosis in the eyes after vitrectomy was 38.9%,and only 5.6% in the other group;the incidence of posterior subcapsular opacities in the eyes after vitrectomy was 34%,and 4.2% in the eyes without accepting vitrectomy.Our results showed that nuclear sclerotic changes correlated with not only vitrectomy,but also the time after surgery;Posterior subcapsular opacities were related to vitrectomy and gas injection.
