简介：目的：评价青光眼患者的生存质量并探讨影响其生存质量的因素。方法：采用国家眼科研究所视功能问卷-25,对126例青光眼患者的生活质量进行评价。结果：青光眼患者的生存质量普遍下降,不同程度的视力损害明显影响着患者的生存质量得分（P〈0.01）。多因素逐步直线回归显示：生存质量的得分与年龄、经济收入、遵医行为有密切关系（P〈0.05）。结论：在保护青光眼患者视功能的同时,要重视其社会、心理等因素,给予其必要的健康教育和心理辅导,以期提高其生存质量。

简介：目的：对影响糖尿病患者视网膜血管形态变化的相关因素进行分析。方法：选取2012-01/2016-09期间于本院就诊的2型糖尿病患者312例为研究对象。对患者进行、眼底摄片及相关实验室检查。以患者年龄、性别、病程、是否吸烟、饮酒,是否合并高血压、高血脂或糖尿病肾病等作为分组因素,比较不同组间患者出现视网膜血管形态变化的发生率,将有意义的因素再次引入Logistic回归方程,筛选出糖尿病患者视网膜血管形态变化的独立危险因素。结果：所选的312例2型糖尿病患者中,伴视网膜血管形态异常组169例,不伴视网膜血管形态异常组143例。单因素分析结果显示,年龄、病程、合并高血压、高血脂或糖尿病肾病与视网膜血管形态变化显著相关（P〈0.05）,性别、是否吸烟、饮酒等与视网膜血管形态异常的发生无显著相关性（P〉0.05）。将发生视网膜血管形态异常作为因变量,上述具有统计学意义的分组因素作为自变量,经Logistic逐步回归分析结果显示,病程、患者合并高血压或糖尿病肾病是发生视网膜血管形态异常的独立危险因素（P〈0.05）。结论：病程增加、患者合并高血压或糖尿病肾病是糖尿病患者发生视网膜血管形态变化的独立危险因素。早期诊断与干预,采取措施控制血压稳定,减少肾脏损害可降低视网膜血管病变的发生率,同时减少糖尿病所引发的大血管病变,减少心脑血管不良事件的发生。

简介：目的分析阻塞性睡眠呼吸暂停低通气综合征（obstructivesleepapneahypopneasyndrome，OSAHS）各指标与听力变化之间的关系。方法随机选取行多导睡眠监测的OSAHS患儿62例，呼吸暂停低通气指数（apneahypopneaindex，AHI）大于等于5的32例为试验组，小于5的30例为对照组，同时行声导抗、瞬态诱发性耳声发射、畸变产物耳声发射及听性脑干反应、鼻咽侧位X线片、纤维鼻咽镜检查。结果两组问听性脑干反应V波阈值试验组左耳（31．85±14．07）dBnHL，右耳（33．50±12．68）dBnHL；对照组左耳（20．76±7．50）dBnHL，右耳（23．09±6．39）dBnHL，两组间左耳（P=0．003）、右耳（P=0．002）差异均有统计学意义。经非条件Logistic回归分析结果显示：变量AHI和声导抗声顺值是OSAHS患儿听力下降的危险因素。结论缺氧是OSAHS患儿听力变化的决定因素，对OSAHS患儿应尽早治疗。（中国眼耳鼻喉科杂志，2010，10：229-231）

简介：目的探讨干眼症发生的主要相关因素。方法选择2006年5月至2007年11月间眼科门诊就诊的屈光不正、眼底病患者及行常规体检的健康者133人为研究对象，主要包括问卷调查和干眼病检测两个部分。问卷调查内容有人口学特征、工作环境、生活习惯与全身疾病等。先进行单因素分析，找出与干眼症发病相关联的因素，然后再对有意义的因素进行多因素综合分析，找出干眼病发生的主要危险因素。结果单因素分析结果表明：与干眼症发病相关的因素有年龄、荧光屏接触时间、野外工作时间、工作环境、吸烟和糖尿病。行Logistic回归分析，最终有统计学意义的因素为：年龄、野外工作时间和工作环境。结论就纳入本研究的因素而言，影响干眼症发病的主要因素是年龄、野外工作时间和工作环境，而荧光屏接触时间、吸烟及罹患糖尿病在一定程度上影响着干眼病的发生。

简介：目的：运用PlusoptixA09小儿自动测光仪探测雅加达地区学龄前儿童屈光不正及其他眼病的发生情况。方法：对雅加达的三个地区（南唐格朗,勿加泗和西雅加达）三所幼儿园中,平均年龄4.46岁（2～6周岁）的儿童进行屈光不正及其他眼病检测。结果：受检的166名儿童中,男生占51.2%（n=85）,女生48.8%（n=81）。视力筛选以Arthur修定标准为参考,并为15.67%（n=26）的儿童做更深一步的全面性眼部检查。其中2人高度远视,14人严重散光,6人散光加近视,1人屈光参差,1人无法检测,2人患有其他眼病（由慢性咳嗽导致的先天性眼睑下垂、严重瘀斑和结膜下出血）。结论：本研究表明,运用PlusoptixA09测出弱视危险因素结果为15.67%。此项数据表明,印度尼西亚地区医疗保健人员对学龄前儿童视力筛选工作不够重视,尤其是对不可逆性弱视的危害性重视度不够。

简介：青光眼是一种严重的致盲眼病,致盲率高且不可逆转.其中,我国的原发性青光眼类型以原发性闭角型青光眼为主.近年来随着原发性青光眼诊断水平的不断提高,对原发性闭角型青光眼危险因素的研究更加深入,本文主要就其危险因素(人口统计学、跟部因素、遗传因素、精神心理因素等)进行综述,以期对预防及诊断有所帮助.

简介：青光眼是一种严重的致盲眼病,致盲率高且不可逆转,严重威胁患者的生活质量,近年来随着原发性青光眼诊断水平的不断提高,对POAG危险因素的研究更加深入,本文主要就原发性开角型青光眼的危险因素(年龄、性别、种族、遗传因素、眼内压、血压、吸烟、饮酒、近视、糖尿病等)进行综述,以期对预防及诊断有所帮助。

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：糖尿病性黄斑水肿（DME）是糖尿病患者视力下降的主要原因,但其发病确切机制目前尚不完全清楚,但可以明确的是多种因素参与了DME的发生和进展,本文就目前该病相关危险因素的研究进展作一概述。

简介：糖尿病性视网膜病变(Diabeticretinopathy,DR)是最为常见的致盲性眼底病变之一,其发病机制不明.长期以来,早期对于糖尿病性视网膜病变的治疗只是单纯控制血糖,但这并不能完全阻止糖尿病性视网膜病变的进一步发展.因此,研究全身相关因素的影响作用十分重要.近年来,国内外大量研究认为,许多全身因素对糖尿病性视网膜病变发生发展起重要作用.本文综述此方面成果,总结必须严格控制的相关危险因素,为最终通过全身综合干预以早期控制糖尿病性视网膜病变提供思路.
