简介:目的:探讨术前注射曲安奈德(TA)联合25G微创玻璃体视网膜手术(vitreoretinalsurgery,VRS)治疗增生型糖尿病性视网膜病变(proliferativediabeticretinopathy,PDR)的效果。方法:选取我院眼科需行VRS治疗的PDR患者108例108眼随机分为两组,VRS+TA组:VRS术前1wk行玻璃体腔注射TA的患者54例;VRS组:直接行VRS治疗患者54例,比较两组患者手术情况、术前、术后3mo裸眼视力、最佳矫正视力,术前、术后1wk,1、3mo眼压和并发症情况。结果:VRS+TA组手术时间、电凝率、医源性裂孔率和术中出血率显著短于或低于VRS组,差异有统计学意义(P〈0.05),而两组患者眼内填充物比较无统计学差异(P〉0.05);两组患者术后3mo裸眼视力和最佳矫正视力较术前均得到显著提高,差异有统计学意义(P〈0.05),两组间比较差异无统计学意义(P〉0.05);VRS+TA组术后1、3mo眼压较术前显著升高,差异有统计学意义(P〈0.05),两组间比较差异无统计学意义(P〉0.05);VRS+TA组前房渗出率显著低于VRS组,差异有统计学意义(P〈0.05),但两组并发症总发生率差异无统计学意义(P〉0.05)。结论:PDR患者行VRS治疗前1wk注射TA,可降低手术难度,缩短手术时间,并减少术中、术后并发症,利于患者术后视力改善。
简介:对有晶状体眼植入后房型人工晶状体是矫正屈光不正的有效方法,植入的后房型人工晶状体目前主要有可植入式接触镜(implantablecontactlens,ICL)和有晶状体眼屈光性晶状体(phakicrefractivelens,PRL)。对术后患者主观视觉质量(视力、对比敏感度)、客观视觉质量(波前像差、点扩散函数、斯特尔比率及光学传递函数)的研究显示,主观视力的提高也伴随着客观视觉质量的改善,但部分患者术后出现光晕及眩光症状。本文主要对ICL和PRL植入术后主观及客观视觉质量的临床研究做一综述,对可影响视觉质量的术后并发症如晶状体前囊膜下混浊、青光眼及角膜内皮功能异常等需进一步远期随访。

简介:目的检测糖尿病视网膜病变(DR)患者经曲安奈德治疗后,眼动脉、视网膜中央动脉收缩期血流速峰值(PeakSystolicVelocity;PSV)的变化,探讨曲安奈德对其血流动力学的影响。方法对13例糖尿病视网膜病变患者(13只眼)经玻璃体腔注射曲安奈德治疗前后,应用彩色多普勒超声成像技术对比研究眼动脉及视网膜中央动脉的收缩期血流速峰值(PSV)的变化。所有患者都随访3个月,分别于治疗后1周、1个月、3个月测量眼动脉及视网膜中央动脉的收缩期血流速峰值。结果所有患者都完成了治疗并随访3个月,视网膜中央动脉(CRA)的收缩期血流速峰值(PSV)在治疗前与治疗后1周,无明显差别(P〉0.05)。在治疗前与治疗后1月,3月两时间点上测量,眼动脉(OA)及视网膜中央动脉(CRA)的收缩期血流速峰值(PSV)有显著差异(P〈0.05)。结论曲安奈德(TA)可以通过抑制炎症反应,下调炎症因子,抑制新生血管形成,改善眼动脉和视网膜中央动脉的血管张力,从而改善动脉血流速峰值,对减少糖尿病视网膜病变的发展起到一定作用。
