简介:准分子激光角膜切削术是九十年代在我国兴起的角膜屈光手术。近年来有诸多成功报道。但是,对于PBK术后的远期疗效乃是医生和患者极为关注的问题。我院自1996年4月开始用PRK治疗近视,效果较好,现对PRK术后5年以上患者进行随诊观察345例671眼,结果报告如下。资料与方法

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:探讨青光眼白内障联合手术对青光眼患者泪液黏蛋白5AC水平(MUC5AC)及眼表功能的影响。方法:选择2011-12/2014-06入住我院的28例行青光眼白内障联合手术青光眼患者作为观察组,同时选择28例未行手术治疗的青光眼白内障患者作为对照组,选择同期在我院进行体检的30名健康者作为健康对照组。比较三组受试者术前1d;术后3,6mo时的泪液MUC5AC水平及眼表功能评分。结果:两组患者术前泪液NUC5AC含量明显低于健康对照组(P〈0.05),眼表功能评分明显高于健康对照组(P〈0.05)。观察组术后1mo泪液MUC5AC水平显著低于术前(P〈0.05),术后3moMUC5AC含量逐渐升高至术前水平,术后6mo时泪液MUC5AC水平均显著高于术前(P〈0.05);术后1mo眼表功能评分显著高于术前(P〈0.05),术后3mo时,眼表功能评分逐渐降低,术后6mo时眼表功能评分均显著低于术前(P〈0.05)。而对照组在术后6mo期间,随着时间的推移,泪液MUC5AC含量逐步降低,眼表功能评分逐步升高。结论:青光眼白内障联合手术术后可使青光眼患者MUC5AC水平暂时性降低,眼表功能评分暂时性升高,但术后3mo后,可逐步改善。
