简介:目的探讨玻璃体腔注射雷珠单抗辅助23G玻璃体切割治疗增殖期糖尿病视网膜病变的优质护理。方法通过对28例28眼采用玻璃体腔注射雷珠单抗辅助玻璃体切割治疗糖尿病患者并发视网膜增殖期病变存在的主要护理问题,针对患者治疗各阶段,责任护士提供全程、连续、系统的优质护理服务,加强护患沟通,提高护理质量,缩短手术时间,减少并发症的发生。结果24眼一次性手术复位成功(85.7%)术后三个月取出硅油,其中有4例伴有晶状体混浊的同时行晶状体超声乳化联合人工晶体植入术;4例硅油填充下仍然存在下方局限性视网膜增殖,术后三个月取出硅油再次切割增殖膜然后注入C3F8气体填充,随访至气体完全吸收,视网膜复位。结论对玻璃体腔注射雷珠单抗辅助23G玻璃体切割治疗增殖期糖尿病视网膜病变的患者提供优质护理,可缩短手术时间,减少并发症的发生,提高病人及家属的满意度,提升患者的康复效果,是手术取得成功的关键因素。
简介:目的:通过测定糖尿病性白内障患者血清中糖代谢指标、胰岛素抵抗与房水和血清中炎症因子的水平,探讨其相关性。方法:随机选取我院2017-02/2018-01糖尿病性白内障患者69例(观察组)和白内障患者65例(对照组),检测两组患者血清中糖化血红蛋白(HbA1c)、空腹血糖(FPG)、空腹胰岛素(FINS)的水平,计算胰岛素抵抗指数(HOMA-IR);同时检测房水和血清中的胰岛素样生长因子-1(IGF-1)、白细胞介素-6(IL-6)含量,对HbA1c、HOMA-IR与房水和血清中IGF-1、IL-6含量进行相关性分析。结果:对照组血清中的FPG、HbA1c、HOMA-IR,以及房水和血清中IGF-1、IL-6含量显著低于观察组,差异有统计学意义(均P<0.05)。HbA1c与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。HOMA-IR与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。结论:糖尿病性白内障患者HbA1c、HOMA-IR与房水及血清中的IGF-1、IL-6含量具有相关性,通过对上述指标的测定可以辅助判断病情。
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:观察单眼严重白内障合并外斜视患者术后临床效果。方法:回顾我院2010-03/2012-12单眼严重白内障合并外斜视行白内障摘除联合人工晶状体植入手术的患者资料45例。术前44例较差眼视力均〈0.05,1例2岁患儿无法配合视力检查。随诊观察术后6mo患者的最佳矫正视力、眼底、斜视度、双眼单视功能及复视情况。结果:先天性白内障患者2例中有1例患儿2岁,无法配合视力及复视检查,眼底正常;另1例患儿术后无同时知觉,无复视。5例不明原因中青年单眼白内障患者中,有3例患者术后视力〉0.6,眼底正常,术后眼位正,有双眼单视;2例患者术后视力为指数,眼底有异常,术后斜视度与术前无变化,无同时知觉,无复视。38例老年性白内障患者中,有31例患者术后有双眼单视;3例患者术后斜视度与术前无差异,无同时知觉,无复视;3例患者术后斜视度与术前无差异,有复视,6mo内复视均自行消除;1例患者外斜10o,术后出现复视,且6mo内无改善,可用12?矫正,建议戴镜治疗。结论:单眼严重视力障碍合并外斜视的成年患者多数术后可自行纠正眼位,获得一定的双眼单视功能。
简介:目的:探讨糖尿病患者黄斑中心凹下脉络膜厚度(SFCT)与脉络膜血流动力学指数及糖化血红蛋白之间的关系。方法:选择在我院眼科及内分泌科住院治疗的2型糖尿病患者78例156眼作为研究对象。其中男39例,女39例,平均(59.8±6.2)岁。根据ETDRS糖尿病视网膜病变分级方法,将患者分为无视网膜病变组、轻中度NPDR组、重度NPDR组、PDR组。采用EDI-OCT与超声多普勒对四组患者进行脉络膜厚度测量与脉络膜血流动力学指数测量。并记录所有患者的血糖化血红蛋白含量。采用多元线性回归分析SFCT与血流动力学指数与糖化血红蛋白的相关性。结果:NDR患者组舒张末期血流速度(EDV)明显高于其它患者组,SFCT较其它各组偏薄,差异有统计学意义。四组患者收缩期峰值血流速度(PSV)无统计学差异;重度NPDR组血管阻力指数(RI)高于NDR组及轻中度NPDR组;PDR组RI进一步增高,差异有统计学意义。SFCT与糖化血红蛋白有显著正相关性(b=0.540,P〈0.001);SFCT与DR分级(P=0.341)、PSV(P=0.770)、EDV(P=0.131)及RI(P=0.084)无显著相关性。结论:糖尿病患者SFCT与血流动力学各指数无相关性。糖化血红蛋白是糖尿病患者SFCT的影响因素之一。
简介:目的:总结抗结核药物所致的视神经炎临床特点,探讨防治对策。方法:回顾性分析广州市胸科医院2003-01/2013-01门诊和病房患者在抗结核治疗过程中出现药物性视神经炎的临床特点。结果:抗结核药物治疗引起的药物性视神经炎不多见(17/60000),以球后视神经炎多见,引起视神经炎的抗结核药物主要是乙胺丁醇,其次是异烟肼、链霉素。明确诊断后及时停用与视神经炎相关的结核药,并根据病情给予补充维生素,扩张血管,激素等治疗,患者的视力都有不同程度的提高。结论:在使用抗结核药期间要注意患者视力变化情况出现突发视力下降应作眼科检查,并及时给予干预,防止失明的严重后果。
