简介:近年来国外在开角型青光眼遗传学方面的研究已取得显著进展,已确定了许多染色体位点与开角型青光眼发病有关,并且进行了相关基因的定位与克隆,以及其突变位点的分析,本文就开角型青光眼相关基因的研究进行综述.
简介:目的探讨原发性闭角型青光眼(primaryangle—closureglaucoma,PACG)发病的危险因素,寻找有意义的早期筛查指标,指导早期临床预防性治疗。方法收集60例PACG患者和50例健康对照者的视力、眼压、眼睑、晶状体、眼底、前房深度、房角镜、视野等基本眼科检查及年龄、性别、家族史、糖尿病、高血压病,有无吸烟史、饮酒史等资料进行分析。结果单因素分析显示与PACG具有较显著联系的有高血压病和前房深度、角膜横径、睫状体晶状体距离。非条件Logistic回归分析发现只有前房深度有统计学意义(P〈0.05),OR为2.687,95%可信区间为1.078~4.000。结论高血压病、浅前房、角膜横径小、睫状体晶状体距离小是PACG发病的危险因素,其中浅前房是PACG发病的独立危险因素。(中国眼耳鼻喉科杂志,2010,10:224-226)

简介:目的探讨桥小脑角疾病的相位平衡快速梯度回波(Balance-FastFieldEcho,B-FFE)序列MRI影像学特点,评价B-FFE序列对桥小脑角疾病的诊断价值.方法应用B-FFE序列对136例桥小脑角病变者(三叉神经痛131例、半面痉挛5例)进行MRI检查,观察桥小脑角神经、血管、肿瘤显像情况,并与手术中资料进行比较.结果131例三叉神经痛患者中,117例为原发性三叉神经痛,MRI显示有血管压迫者102例,术中证实有血管压迫者95例,行显微血管减压+神经梳理术;14例为继发性三叉神经痛,均为桥小脑角占位性病变,术后病理证实7例为胆脂瘤,2例为听神经瘤,5例为脑膜瘤;5例半面痉挛患者MRI显示有血管压迫,术中证实有血管压迫,并予以血管减压.结论B-FFE序列MRI成像能清楚显示桥小脑角区三叉神经、面神经与血管的关系及是否有占位性病变,对诊断、术前评估和指导治疗有重要意义.
简介:患者女,57岁,无青光眼病史.因"右眼视物不清20余天"入院,23d前在外院全身麻醉下行"心脏冠状动脉搭桥术",术前给予阿托品0.5mg,鲁米那100mg.术后第一天感右眼视物模糊伴疼痛不适.诊断为"右眼急性闭角型青光眼"入院查体;视力右0.4,左0.8,眼压:右32mmHg,左13mmHg,(1mmHg=0.133kPa),双眼角膜尚透明,前房略浅,瞳孔中度大,对光反射消失,前房角镜下见房角NⅢ~Ⅳ,晶状体轻度混浊,右眼晶状体后囊下见青光眼斑,双眼C/D≈0.5.诊断为"双眼闭角型青光眼".在局部麻醉下行右眼巩膜分层咬切术后,眼压10~13mmHg,病情稳定,左眼择期行激光虹膜周切术.
简介:目的:观察两种不同方法治疗急性闭角型青光眼的疗效。方法:回顾性研究,收集我院2010—01/2012—12诊断为急性闭角型青光眼115例115眼患者,分为观察组和对照组,其中45例45眼行前房穿刺术减压后再行小梁切除术治疗,列为观察组,70例70眼行药物减压后,再行小梁切除术治疗,列为对照组,比较两组患者治疗效果。术后观察视力、眼压、并发症等。结果:两组患者治疗前后眼压的差异均具有显著的统计学意义(P〈0.05);所有眼术后视力均有所提高,术后观察组视力恢复较对照组好,比较差异有统计学意义(P〈0.05)。结论:采取前房穿刺术联合小梁切除术治疗急性闭角型青光眼疗效好。
简介:目的探讨舒适护理在急性闭角型青光眼手术患者中的应用效果。方法将我科未开展舒适护理模式的2008年3月-2009年12月66例患者设为对照组,已开展舒适护理的2010年3月-2011年11月92例患者设为观察组。对照组给予常规护理和指导,观察组在常规护理的基础上,采用舒适护理方式并评价其效果。结果通过对青光眼患者的舒适护理干预,观察组焦虑状况低于对照组,病人舒适度高于对照组,两组差异有统计学意义(P〈0.05),观察组满意率明显优于对照组(P〈0.01)结论舒适护理可以增加患者的舒适程度,减轻负性情绪,对疾病的治疗、康复起积极作用。同时,有利于增进医患关系的和谐,提高护理满意率。
简介:目的:观察倍频Nd:YAG激光联合YAG激光行周边虹膜切除术治疗急性闭角型青光眼的疗效及并发症。方法:本组共105例,其中临床前期91眼,先兆期32眼,间歇期46眼,均先使用倍频Nd:YAG激光在拟行周边虹膜切孔处分层射击,最后用YAG激光穿透造孔,随访12mo,观察疗效及并发症。结果:术后1~6h眼压暂时性升高,24h后眼压下降,虹膜周切孔均通畅,房角无粘连,3眼周切孔处局限性晶状体混浊。结论:倍频Nd:YAG激光联合YAC激光行周边虹膜切除术是防止闭角型青光眼急性发作的安全有效的手术。
