简介：白内障是目前世界上最主要的致盲原因，也是我国最重要的致盲原因，白内障摘除是治疗白内障的唯一有效方法。然而由于各种原因，我国白内障手术率（CSR）远低于发达国家甚至某些发展中国家。对基层医院的眼科医师和年轻医师进行恰当的白内障手术规范化培训是提高我国CSR的关键之一。

简介：角膜内皮移植是一种针对内皮功能失调患者的靶标性角膜移植术，从萌芽发展至今，已逾半个多世纪，历经几代眼科学者承前启后的摸索和艰难实践，正在一步步朝安全、有效、视力快速康复的方向演进。

简介：在瞬息万变的信息化社会里,加强医学生创新能力的培养是适应医学发展的必要条件。本文结合眼科学的特点,初步探讨在眼科教学活动中医学生创新能力培养所存在的问题和解决方案,为提高医学生的创新能力,更好的服务临床提供帮助。

简介：间歇性外斜视（intermittentexotropia,IXT,X（T））是介于隐性斜视与显性斜视之间的一种过渡型斜视。在各类共同性外斜视中占第一位。间歇性外斜视发病原因主要是集合和分开功能之间平衡失调,集合功能不足以及融合功能低下引起。平均发病年龄岁,女性多发。斜视角随注视距离、注意4力强弱、视力疲劳状态在正位与外斜视间变动。

简介：儿童盲的诊治是视觉2020的优先治疗区域,因为视力障碍的孩子们将面对的是长达一生的失明。全球各种研究表明,有1/3到1/2的儿童盲是可避免或者可治疗的,白内障是可治疗儿童盲的首位病因。

简介：糖尿病性视网膜病变(Diabeticretinopathy,DR)是最为常见的致盲性眼底病变之一,其发病机制不明.长期以来,早期对于糖尿病性视网膜病变的治疗只是单纯控制血糖,但这并不能完全阻止糖尿病性视网膜病变的进一步发展.因此,研究全身相关因素的影响作用十分重要.近年来,国内外大量研究认为,许多全身因素对糖尿病性视网膜病变发生发展起重要作用.本文综述此方面成果,总结必须严格控制的相关危险因素,为最终通过全身综合干预以早期控制糖尿病性视网膜病变提供思路.

简介：<正>今天许多种类的内窥镜已应用于临床诊断。由于优良的光源和光导系统使得精确的观察成为现实。手术可以在电视屏幕下操作,并获得优质的屏幕影像和内窥镜手术像片资料。1959年HopkinsHH博士发明了棒状透镜,1960年StorzK.在此基础上添加了光导纤维,这些形成了现代内窥镜突破性进展。本文总结了与内窥镜发明者StorzK.的谈话内容。早期的内窥镜是JacksonC.医学博士设计的,在许多年内,这个设计没有进一步改进。培养一个内窥镜医师需要许多年时间在实验室用很讲究的方

简介：上课是常规教学中一个很重要的环节,课堂教学的效率高低直接影响到教学质量的好坏。多媒体课件质量、多媒体与传统板书教学的融合以及多媒体教学方式好坏直接决定教学质量,笔者在对这一问题探讨和分析后,试图寻找出一套较为完整的适合于该课程的教学方式,提高学生学习兴趣,使学生掌握教学重点和难点,取得更好效果。

简介：今天,我们在这里召开2005年全国防盲工作研讨会。这次会议的主要内容是:分析全国防盲工作面临的形势和挑战,研究开展防盲工作的重点和策略;研究制定2006-2010年全国防盲工作规划。同时,还要对“视觉第一中国行动”二期启动以来的工作进行总结,对中期评估事宜和下一步工作进行部署。两天的时间,任务还是比较重的,我希望大家借此机会,广泛交流各地防盲治盲工作情况,借鉴各地有益的工作经验,在充分研讨,制定出我国2006-2010年防盲工作规划的同时,研究探索适合我国国情、进一步推进我国防盲治盲工作的政策措施、有效途径。

简介：目的探讨当前基层医院沙眼防治工作中出现的若干问题。方法对门诊记录的14600例沙眼患者依据年龄、生活习惯、卫生习惯、是否接受正规有效治疗以及复诊等情况进行调查和追踪随访。结果沙眼检出率高达22.86%,这与社会因素、个人的生活卫生习惯、不能接受正规有效的治疗和复诊率低密切相关。结论大力推广WHO的SAFE策略,开展＂防沙＂健康教育工作,规范治疗,降低沙眼患病率,提高沙眼疗效。

简介：护理安全是指在实施护理的全过程中，患者不发生法律和法定的规章制度允许范围内以外的心理、机体结构或功能上的损害、障碍、缺陷或死亡。通过对护理安全问题的分析，认为造成护理安全问题和护患纠纷的主要原因有护理人员方面的、管理方面及病人、社会方面的。只有依法行医、恪尽职守、加强自律和道德建设、规范服务行为、改善社会对医院的再认识，建立协调健康的医护关系，合理应用人力资源，优化护理管理制度，增强护理风险意识才能有效解决护理安全问题。

简介：近十几年来，医务工作者与科学工程技术人员密切配合，研发了多种类型的外科手术机器人系统。在国外，每年都有大量的心外科和泌尿外科手术通过机器人完成。一些有预见性的耳鼻喉科医师也对这项新技术进行了积极的探索，展示了令人兴奋的前景。
