简介:目的:探索一种临床实用的前房深度相对定量测量法,初步确定老年人前房深度的正常参考值。方法:裂隙灯光源外转45°,受检眼直视裂隙光,在6点时钟方向测量六个点的前房深度(ABCDEF),以角膜缘处的角膜厚度(CT值)为1计。A:角巩膜缘黑白交界处;B:A点上移1CT;C:B点上移1CT;D:虹膜最高点;E:瞳孔缘;F:晶状体前极。测量了50~75岁的正常老年人,229例229眼,采用双盲法对22例44眼进行了11次重复性检测。结果:女性组ABCDEF点的前房深度均值分别为0.38,0.58,0.89,2.10,2.65和3.26CT;男性组分别为0.71,1.02,1.43,2.37,2.90,3.41CT。女性组每个点的深度均比男性浅(P〈0.05),越近周边部越显著。结论:前房深度六点相对定量测量法可重复性好,实用性强。
简介:目的:观察糖尿病视网膜病变(diabeticretinopathy,DR)患者行全视网膜光凝(panretinalphotocoagulation,PRP)后服药前及服药2mo后患眼的全视野视网膜电图(fullfieldelectroretinogram,ERG)变化,探讨递法明片对DR暗适应功能的保护作用。方法:选择在我医院就诊的重度非增殖性糖尿病视网膜病变(nonproliferativediabeticretinopathy,NPDR)患者55例55眼,随机分为治疗组和对照组。两组均行全视网膜光凝,治疗组光凝后口服递法明片,对照组口服维生素B1片2次/d,10mg/次。PRP后服药前及服药2mo后行全视野视网膜电图检查,观察其暗视视杆反应的变化并进行统计学处理。结果:两组患者服药前及服药2mo后,暗视视杆反应bT值组内及组间比较差异均无统计学意义(P〉0.05);治疗组bA值服药2mo后与服药前相比振幅升高,差异有统计学意义(P〈0.05),与对照组相比治疗组振幅升高较大,差异有统计学意义(P〈0.05)。结论:递法明片可减轻PRP治疗对视网膜的损害,改善患者的暗适应功能。
简介:目的:比较常规泪小管断裂吻合术和鼻内窥镜引导逆行注气法联合5-氟尿嘧啶治疗泪小管断裂的手术时效和疗效。方法:收集秦皇岛市海港医院眼科2009-01/2015-12下泪小管断裂行手术治疗的患者67例67眼的临床资料进行研究。采用数字表法随机将患者分为A组和B组。A组33例33眼行常规泪小管断裂吻合术,B组34例34眼行鼻内窥镜引导逆行注气法联合5-氟尿嘧啶治疗泪小管断裂。分别采用独立样本t检验和Mann-Whitney秩和检验的方法对两组的找到泪小管断端的时间和手术疗效进行比较。结果:A组找到泪小管断端的时间为44.42±10.66min,B组找到泪小管断端的时间为30.06±6.21min,两组比较,差异有统计学意义(t=6.72,P〈0.05)。术后6mo冲洗泪道判断手术疗效,B组疗效优于A组,差异有统计学意义(Z=2.47,P〈0.05)。结论:鼻内窥镜引导逆行注气法联合5-氟尿嘧啶治疗泪小管断裂和常规泪小管断裂吻合术相比,手术时间短,术后疗效佳。
简介:目的观察初学者学习0.7毫米微创白内障手术改良法的临床效果。方法随机选取门诊和住院白内障患者50人,由初学者在老师指导下应用0.7毫米微创白内障手术改良法施行手术。研究内容包括手术时间,术中灌注液应用量,术中并发症等。结果手术时间随着学习的进程总体呈下降趋势,从开始10例平均时间61分22秒下降到第5个10例的18分54秒。特别是30例后下降明显。共7例9次并发症发生。第4例出现后囊破裂,未行玻璃体切割的情况下成功植入人工晶状体于睫状沟内。前10例中共有2例,第2和4个10例中各1例术中角膜上皮水肿。另外还有1例发生后弹力层撕裂,两例切口撕裂,1例结膜水肿。结论经过短期的0.7毫米微创白内障手术改良法训练,初学者可从传统同轴超声乳化安全转换至0.7毫米微创白内障手术。
