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:研究巩膜扣带术(scleralbuckling,SB)联合玻璃体注气术治疗孔源性视网膜脱离(rhegmatogenousretinaldetachment,RRD)的临床疗效及对患者血清中氨基酸、血管内皮生长因子(vascularendothelialgrowthfactor,VEGF)的影响。方法:回顾性分析我院收治的RRD患者150例150眼临床资料,将仅接受SB的患者81例81眼纳入未注气组,接受SB+玻璃体注气术的患者69例69眼纳入注气组,比较两组患者手术疗效和术前、术后血清中氨基酸、VEGF水平等情况。结果:两组患者术后各时间点视网膜复位率比较,差异均无统计学意义(P>0.05);注气组术后1d眼压明显高于未注气组,差异有统计学意义(P<0.05),两组患者术后5d眼压比较差异无统计学意义(P>0.05);两组患者术后术眼裸眼视力较术前均明显改善,差异有统计学意义(P<0.05);术后5d,两组患者血清中组氨酸、谷氨酸、苯丙氨酸、VEGF水平较术前均显著降低,差异有统计学意义(P<0.05),但组间比较差异无统计学意义(P>0.05);两组患者血清中精氨酸、亮氨酸、异亮氨酸、甘氨酸水平与术前比较,差异无统计学意义(P>0.05);术后1mo,两组患者视功能相关生活质量总分和各维目评分均较术前明显升高,差异有统计学意义(P<0.05),但两组间各评分比较差异无统计学意义(P>0.05);注气组术后并发症总发生率为7.2%(5/69)与未注气组的9.9%(8/81)比较,差异无统计学意义(P>0.05)。结论:SB联合玻璃体注气术有助于RRD患者视功能和眼压的早期恢复,降低血清中组氨酸、谷氨酸、苯丙氨酸、VEGF水平,且安全性较高。

简介:目的评价海德堡视网膜断层扫描仪黄斑区视网膜分析系统(macularedemamodule,MEM)的三个技术参数,了解其变异性及可重复性来判断其临床应用价值。方法对78例(78只眼)正常健康志愿者应用海德堡视网膜断层扫描仪黄斑区视网膜分析系统进行检查。分析扫描深度值(Z)、视网膜信号宽度值(W)、水肿指数值(E)三参数的均值及变异系数,并分析黄斑反射图、地形图、信号宽度图、水肿指数图的图像特征。结果黄斑中心0.5mm范围内视网膜扫描深度均值(Z)为1.4430848,变异系数55.6%。W值为795.27±193.53,变异系数17.6%。E值为1.13±0.35,变异系数27.8%。不同个体三参数差异有高度显著性(P<0.01),个体变异较大。不同时间段三参数测量差异无显著性(P>0.05)。结论MEM可对黄斑区视网膜厚度进行量化分析,个体变异较大,但重复性好,HRT-Ⅱ检查适合黄斑疾病的个体随诊观察。
