  • 简介:对于原发性角型青光眼(POAG),治疗的基本原则是通过药物、手术或激光等方式降低眼压,但是患者的日常生活习惯对治疗后眼压的控制、病情的缓解有着不可忽视的影响。日常生活中影响眼压和POAG病情发展的相关因素主要有饮酒、吸烟、运动、肥胖和饮用咖啡、茶等。本文主要就流行病学调查方面研究结果,进行了分析总结,提出在日常生活方面的注意事项,给眼科医生提供相关信息,给患者提供生活指导。

  • 简介:目的:评价并比较180°和360°选择性激光小梁成形术(selectivelasertrabeculoplasty,SLT)治疗原发性角型青光眼(primaryopenangleglaucoma,POAG)的临床效果。方法:POAG患者60例60眼,分别采用532nm倍频Q-开关Nd:YAG激光治疗仪,以光斑400μm,脉冲时间3ns,能量0.3~1.2mJ行180°和360°SLT。观察患者术后6mo的眼压变化。结果:两组患者眼压在激光治疗后均有显著下降,180°组患者术前平均眼压为25.6±2.0mmHg(1kPa=7.5mmHg),术后1h;1d;1wk;1,3,6mo眼压分别为27.1±2.1,16.5±1.9,19.6±1.9,18.5±1.8,19.9±1.9,20.3±1.8mmHg。360°组患者术前平均眼压为25.4±2.1mmHg,术后对应时间点眼压分别为26.6±1.9,15.9±2.0,19.0±2.0,17.8±1.9,18.7±2.0,19.2±1.9mmHg。两组术后1d;1wk;1,3,6mo的眼压与术前相比明显下降,差异均有统计学意义(P〈0.01)。术后两组各时间点眼压的平均下降幅度比较,360°组较180°组术后眼压的平均下降幅度更大,其中术后3mo和6mo差异具有统计学意义(P〈0.05)。结论:360°SLT治疗POAG的疗效可能优于180°SLT。
