软性角膜接触镜在翼状胬肉术后的应用

翼状胬肉（ pterygium）是眼科常见病和多发病,一般认为是受外界刺激而引起的一种慢性炎症性病变,单眼或双眼受犯,因其形状酷似昆虫的翅膀故名为翼状胬肉,中医称为“胬肉攀睛”［1］。目前临床上治疗翼状胬肉以手术为主,传统的翼状胬肉切除术后复发率高,而改良的翼状胬肉切除联合自体球结膜移植术可以极大地降低术后复发率。有研究显示,胬肉切除联合自体球结膜移植术与自体角膜缘干细胞移植术、羊膜移植术,术后复发率并无明显差异［2］。为改善胬肉术后出现明显的畏光、流泪、异物感、疼痛等症状［3］,连云港市第一人民医院眼科开展治疗性软性角膜接触镜治疗翼状胬肉,极大的减少了术后不适反应,取得了良好的治疗效果。

2型糖尿病患者糖尿病视网膜病变不同时期外周血内皮祖细胞的数量变化

Objective To observe the amount of endothelial progenitor cells(EPCs)at different stages of diabetic retinopathy(DR)in patients with type 2 diabetes mellitus(DM).Methods Sixty patients with type 2 DM were divided into no DR(NDR)group,non-proliferative DR(NPDR)group and proliferative DR(PDR)group according to the examination of fundus and fundus fluorescein angiography,20patients in each group.Twenty healthy people were collected as the control group.6 ml blood samples were taken from all the subjects,and then the EPCs contents in peripheral blood were detected by flow cytometry.Results The EPCs contents in peripheral blood of the control,NDR,NPDR and PDR group were(0.0179±0.0047)% ,(0.0151±0.0086)% ,(0.0123±0.1137)% ,(0.0316±0.0294)% .The EPCs contents in peripheral blood of the PDR group was significantly higher than those in others(χ2=43.780,P＜0.05);the EPCs contents in peripheral blood of the NDR and NPDR group were slightly lower than that in the control group(χ2=5.244,P=0.73);the EPCs contents in peripheral blood of the NPDR group was lower than that in the NDR group(χ2=6.0 1 6,P=0.12).Conclusion The EPCs contents in peripheral blood decreases in NDR,NPDR patients,while significantly increases in PDR patients.

全视网膜光凝对糖尿病视网膜病变神经纤维层及黄斑厚度的影响

目的研究糖尿病视网膜病变（DR）及全视网膜激光光凝（PRP）对视乳头旁视网膜神经纤维层（RNFL）厚度及黄斑中心凹视网膜厚度的影响。方法年龄匹配的正常对照组34例66只眼,2型糖尿病（T2DM）无DR患者组20例32只眼,T2DM DR患者组39例46只眼,行PRP治疗组19例20只眼被纳入研究,应用光学相干断层扫描仪（OCT）测量视乳头旁RNFL厚度及黄斑中心凹视网膜厚度,比较各组间的差异。结果 PRP治疗后视乳头旁RNFL厚度（117.5±15.9）μm与DR组（118.7±18.7）μm比较无统计学差异;黄斑区视网膜厚度在DR中明显增厚,PRP治疗后增厚明显。结论 DR行PRP治疗后近期RNFL无明显变化,黄斑区视网膜水肿加重。     

糖尿病视网膜病变发病机制研究进展

糖尿病视网膜病变(diabetic retinopathy,DR)是糖尿病最常见、最主要的微血管并发症之一,已经成为当前全球致盲的重要原因。其基本病理改变是视网膜的血-视网膜屏障的破坏和视网膜新生血管形成,黄斑水肿,最终视网膜脱离,导致失明。高血糖是公认的DR发生和发展的主要危险因素,DR还与多元醇代谢、糖基化终产物、甘油二酯-蛋白激酶C系统、氧化应激和自由基、炎症反应以及细胞因子等有关,但至今其发病机制尚未完全阐明,本文就目前DR的发病机制做一系统性的综述,为DR的治疗提供新的思路。
