【摘要】 目的:总结糖尿病患者白内障术后泪膜的护理对防治干眼发生的作用。方法:随机抽取老年性白内障合并糖尿病患者58例(66眼)行超声乳化白内障吸除术,对照组为随机选取的单纯老年性白内障患者50例(50眼)。分别于术前、术后1d、7d、30d进行症状、角膜荧光素染色(FL)、泪膜破裂时间(break-up time,BUT)、基础泪液分泌试验(SchinmerⅡtest,SIt)调查,并给以相应的护理、防护措施。结果:两组超声乳化白内障吸除术后1d、7d、30d干涩、异物感加重,与术前比较BUT明显缩短,SIt分泌增加,FL染色率也明显增多。差异均有统计学意义(P<0.01)。两组无论是术前还是术后30 d BUT、及SIt差异均有统计学意义(P<0.05),糖尿病组术后FL染色率明显高于对照组,两组间经x~2检验,差异有统计学意义。结论:糖尿病患者白内障术后可致泪膜稳定性下降,部分患者泪膜比术前更加不稳定。因此术后补充人工泪液,给以特殊对症护理,促使泪膜功能恢复,对糖尿病患者尤为重要。更多还原

【Abstract】 Objective:To evaluate tear film changes and dry eye syndrome following phacoemulsication in diabetics.Methods:This randomized study involved 58 cases(66 eyes) with diabetes cataract and 50 cases(50 eyes) with cataract who underwent phacoemulsification. Tear break-up time(BUT),SchinmerⅡtest(SIt) value and corneal fluorescein staining(FL) were measured preoperatively and 1 d,7d,30d postoperatively.Results:At 1 d,3 d and 7 d postoperatively,the subjective complains of dry eye,the mean SIt and FL scores increased significantly,and the mean BUT decreased significantly(P<0.01).In addition,the mean BUT and SIt of diabetes group was less than those of normal group preoperatively and 30 d postoperatively(P<0.05).The score of corneal FL of diabetes group was higher than that of normal group.Conclusion:Phacoemulsification reduces the stability of tear film of diabetic patients.Preventions should be taken, like artificial tears.更多还原
