简介:目的探讨医院及家庭联合治疗大龄儿童弱视的临床效果。方法选择7~15岁的大龄儿童73例(113眼),采用医院及家庭联合实施弱视综合疗法对患儿进行治疗,并对临床资料进行总结、分析。结果113眼中有96眼有效,总有效率84.96%,其中基本痊愈61眼(53.98%)、进步35眼(30.97%)、无效17眼(15.93%)。17例无效眼中,屈光度超过±10.00D者6眼、斜视伴双眼无同视功能5眼、眼颤者1眼、散光超过4.00D者2眼、家庭不配合未坚持治疗者3眼。轻、中度弱视的疗效优于重度弱视;中心注视的疗效优于旁中心注视。结论医院及家庭联合治疗大龄儿童弱视能取得满意疗效,需要医务人员、家属和儿童的共同配合。只有充分调动弱视患儿成长环境中关系密切的群体力量,才能提高其治疗效果。因此对大龄儿童的弱视治疗,除科学、系统及规范的治疗外,还应积极地提高家庭支持度。

简介:目的对眼科住院医师实施白内障囊外摘除术及人工晶体植入术中,手术并发症的预防及处理能力培训探讨。方法开展防盲治盲工作中,住院医师共施行215例(235只眼)的白内障囊外摘除术及人工晶体植入手术,对发生并发症进行回顾性分析。结果术后发生的手术并发症:后囊破裂15只眼(6.4%),虹膜脱出5只眼(2.1%),虹膜根部离断3只眼(1.3%),角膜水肿45只眼(19.1%),瞳孔上移10只眼(4.3%),前房皮质残留2只眼(0.9%),后囊瞳孔区皮质残留2只眼(0.9%),继发性瞳孔阻滞性青光眼1只眼(0.4%),黄斑囊样水肿1只眼(0.4%)。结论后囊膜破裂和角膜水肿是本组白内障囊外摘除术及人工晶体植入手术主要并发症,住院医师手术者应规范掌握手术要点是预防并发症发生的关键,对出现的手术并发症应积极妥善处理是减少并发症有效措施。
简介:目的:观察翼状胬肉切除联合自体球结膜瓣移植术后,局部应用1g/L环孢霉素A对胬肉复发的抑制效果。方法:对原发性翼状胬肉患者58例58眼进行前瞻性研究。所有入选眼均采用翼状胬肉切除联合自体球结膜瓣移植术,根据术后是否应用1g/L环孢霉素A滴眼液分为试验组和对照组。术后追踪随访1a,观察患者的胬肉复发率。结果:术后试验组基础泪液分泌试验(SchirmerⅠtest,SⅠt)结果明显优于对照组(9.93±1.59vs8.47±1.53mm/5min);SⅠt结果也显示1g/L环孢霉素A使患眼术后的泪液分泌量较术前有所增加。术后1a试验组与对照组的胬肉复发率分别为10%和39%。对照组并发症的出现率要高于试验组,差异具有统计学意义(P=0.029)。结论:翼状胬肉切除术后局部应用1g/L环孢霉素A滴眼液能够安全有效地降低胬肉的复发率。
