简介：<正>在文献中对白内障手术和人工晶体(IOL)植入后的炎性反应、IOL前纤维样膜形成的机理及引起继发性青光眼的原因已有详细的报道,但未提及由纤维样膜堵塞房角并可引起难以降低的高眼压。1993年以来我科在白内障囊外摘除和人工晶体植入术后的病例中,先后观察到13眼因房角膜性堵塞引起的高眼压,它们的临床表现不同于通常白内

简介：目的对开展国际防盲合作项目中实施项目管理方法进行探讨。方法采用回顾方法对国际防盲合作项目中项目管理方法进行分析。结果国际防盲合作项目中由于采用规范的项目管理，项目实施中无违规现象发生，从而保证防盲合作项目按时、超额完成项目目标，获得极佳项目社会影响并获得项目外方的首肯，项目将可持续发展。结论正确认识和规范国际防盲合作项目进行项目管理，有助于项目开展，合理地分配资源、推广应用项目成果，促成防盲合作项目的可持续发展，所以建立国际防盲合作项目管理体系是可行及必要的。

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。

简介：目的以接受免费白内障手术的患者电话随访结果为依据,对我省防盲项目完成效果进行评价、分析,探讨提出加强和完善基层医院眼科参与大规模防盲项目患者的可持续随访体系。方法通过以电话随访的方式,对2012年云南省'光明工程'6万例免费白内障手术患者中随机抽取2000例患者就手术视力提高程度及满意度进行电话随访。随访统一使用云南省卫生厅《2012年云南省'光明工程'患者电话随访表》,由专人于4周内完成电话随访。结果患者术后视力明显提高者占90.20%;患者对术后满意度达93.27%;从生活不能自理到能自理占86.41%;术后生活质量明显提高占85.79%;术后患眼有不适者占17.76%;知道如出现不适如何处理的患者占70%;新农合占93.81%,居民医保5.56%,职工医保1.64%,其他医保占0.88%;所有患者均为免费手术,无自付比例。结论在基层开展大规模集中白内障防盲项目的过程中,在严格监控患者术后质量、手术费用、住院天数、降低患者的医疗费用的同时,更应该加强对手术患者的长效管理机制,建立合理的患者随访体系,总结经验,不断完善工作流程,真正改善患者的生活质量,提高患者满意度,体现防盲工作的真正含义。

简介：目的方法结果结论总结我院2009年完成《中西部地区贫困白内障患者救治项目》白内障手术情况。对30例白内障患者根据眼部情况行不同的白内障手术。术后所有患者视力均有提高,脱盲率100%,无严重并发症。《中西部地区贫困白内障患者救治项目》作为一项民生工程,惠民利民。
