简介:目的:评价七叶洋地黄双苷滴眼液治疗近视患者准分子激光原位角膜磨镶术(1aseffnsitukeratomileusis,LASIK)后视疲劳的临床疗效。方法:对200例400眼近视患者行LASIK手术,随机分成两组。100例为试验组应用七叶洋地黄双苷滴眼液,另100例为对照组应用潇莱威滴眼液。分别于手术前、用药后1,2,4wk评估患者术后视疲劳的症状和体征,同时观察药物不良反应。结果:随着术后时间的延长,试验组和对照组近视患者视疲劳症状逐渐缓解,在术后1,2wk时,试验组的视疲劳评分低于对照组,两组差异有统计学意义(t=3.160,P=0.001;t=2.727,P=0.0025);术后4wk时,两组的差异无统计学意义(t=1.423,P=0.10)。结论:随着观察时间的延长,LASIK术后患者视疲劳症状可逐渐得到恢复和改善,七叶洋地黄双苷滴眼液对改善LASIK术后早期视疲劳症状有效。
简介:目的:比较单用贝伐单抗与贝伐单抗联合曲安奈德治疗糖尿病黄斑水肿疗效。方法:回顾性比较随机研究。对21例42眼黄斑水肿的糖尿病患者进行了评估。单眼内注射1.25mg贝伐单抗(IVB组),在同组的眼玻璃体内注射1.25mg贝伐单抗和1mg曲安奈德(IVTA-IVB组)。使用光学相干断层扫描(OCT)、ETDRS视力和眼压测量黄斑中心厚度(CMT)。结果:平均随访时间为4.7±1.5mo。在IVB组和IVTAIVB组中,注射前平均CMT分别为494.7±114.4μm,546.8±165.6μm;第一个月分别为430.4±133.2μm,363.7±105.3μm;第三个月分别为484.8±167.4μm,407.3±108.7μm;六个月后分别为550.4±191.5μm,516.8±158μm。第一个月和第三个月存在显著差异(P<0.05)。在IVB组和IVTA-IVB组中,注射前平均ETDRS视力数分别为57.1±13.5,48.9±13.9;第一个月分别为2.2±14,58.8±12.1;第三个月分别为59±13.7,59.3±13.6;第六个月分别为55.6±14.9,55.5±8.7。第三个月和第六个月存在显著差异(P<0.05)。IOP无差异。第一次注射后IVTA-IVB组在第三个月时视力最佳并持续6个月,而IVB组在第一个月时视力最佳但仅持续了3个月。结论:6个月后发现,IVTA-IVB组较IVB组疗效显著,且无激素依赖性并发症。
简介:目的:探讨非诺贝特联合23G微创玻璃体切割手术在糖尿病视网膜病变(DR)治疗中的临床应用价值。方法:选取2015-10/2017-11在我院接受治疗的DR患者102例102眼为研究对象,按照随机数字表法分为观察组和对照组,每组51例51眼,两组患者均行23G微创玻璃体切割术,术后第1d起,对照组给予常规降糖、降压及改善微循环治疗,观察组在对照组的治疗基础上联合非诺贝特治疗,均连续治疗3mo。对比两组患者术中及术后基本情况(手术用时、术中出血量、围手术期并发症发生率、住院时间)、术前和术后3mo血脂/[总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)/]及血清相关因子/〖脂蛋白相关磷脂酶A2(Lp-PLA2)、血管内皮生长因子(VEGF)/〗水平,随访至术后6mo,比较两组患者视网膜病变复发率。结果:两组患者手术用时、术中出血量、围手术期并发症发生率及住院时间比较,差异均统计学意义(P〉0.05)。术前两组患者TC、TG、LDL-C、HDL-C水平比较,差异均统计学意义(P〉0.05);术后3mo观察组患者TC、TG、LDL-C水平均低于对照组,HDL-C水平高于对照组,差异均有统计学意义(P〈0.05)。术前两组患者血清Lp-PLA2、VEGF水平比较,差异均统计学意义(P〉0.05);术后3mo观察组患者血清Lp-PLA2、VEGF水平均低于对照组,差异均有统计学意义(P〈0.05)。术前两组患者视功能生存质量问卷活动受限、感觉适应、心理、社交各项评分及总分比较,差异均统计学意义(P〉0.05);术后3mo观察组患者视功能生存质量问卷各项评分及总分均低于对照组,差异均有统计学意义(P〈0.05)。术后随访6mo,观察组复发,对照组复发率为5.9%(3/51),组间比较差异统计学意义(P〉0.05)。结论:非诺贝特联合23G微创玻璃�
