简介：世界各地糖尿病增加是主要由于2型糖尿病患者的人数在上升。2型糖尿病越来越常见是因为：随着人的寿命延长,糖尿病更多发生在中老年人中。随着人们越来越多地迁移到市区,运动减少,吃得更多,不健康的食物,越来越多的人正变得肥胖成为2型糖尿病的主要原因。糖尿病增加一系列的眼部疾病风险,包括白内障,但是与糖尿病有关盲的主要原因是糖尿病视网膜病变（DR）。糖尿病视网膜病变通常在患糖尿病后的十至二十年之间发生并且当糖尿病未确诊及未治疗时发展更快。

简介：医疗系统的前景是什么？作为眼科医疗工作者,我们不仅要治疗眼睛,我们更要治疗患者。同样,眼科医疗并非在真空中作业,而是从属于更宽泛的医疗保健系统。当我们的工作需要如此之多的人力之时,很可能让人忘记工作的大背景是什么。然而,

简介：过敏性眼表疾病是眼科门诊常见的眼部炎症。由于眼表暴露在各种各样的过敏原下,使眼部易导致过敏性反应。过敏性眼部疾病最特征的表现是眼部的瘙痒感,表现为双侧性,临床表现因人而异。

简介：目的探讨自我管理项目在门诊青光眼患者中的应用及效果。方法将112例门诊青光眼患者随机分为56例对照组、56例干预组。对照组给予门诊常规药物治疗和常规健康教育指导;干预组在门诊常规药物治疗基础上,进行自我管理项目干预,比较两组病人的自我管理行为、自我效能水平和生活质量。结果干预后12周,干预组自我管理行为、自我效能水平和生活质量显著优于对照组（P〈0.05）。结论自我管理项目干预能提高青光眼患者自我管理行为、自我效能水平和生活质量。
