简介:目的:运用PlusoptixA09小儿自动测光仪探测雅加达地区学龄前儿童屈光不正及其他眼病的发生情况。方法:对雅加达的三个地区(南唐格朗,勿加泗和西雅加达)三所幼儿园中,平均年龄4.46岁(2~6周岁)的儿童进行屈光不正及其他眼病检测。结果:受检的166名儿童中,男生占51.2%(n=85),女生48.8%(n=81)。视力筛选以Arthur修定标准为参考,并为15.67%(n=26)的儿童做更深一步的全面性眼部检查。其中2人高度远视,14人严重散光,6人散光加近视,1人屈光参差,1人无法检测,2人患有其他眼病(由慢性咳嗽导致的先天性眼睑下垂、严重瘀斑和结膜下出血)。结论:本研究表明,运用PlusoptixA09测出弱视危险因素结果为15.67%。此项数据表明,印度尼西亚地区医疗保健人员对学龄前儿童视力筛选工作不够重视,尤其是对不可逆性弱视的危害性重视度不够。
简介:目的探讨用改良圈匙娩核并注重粘弹剂应用对防止小切口非超声乳化白内障囊外摘出人工晶体植入术并发症的作用。方法用改良圈匙娩核并注重粘弹剂应用对355例白内障行小切口非超声乳化白内障人工晶体植入术。结果术后三天矫正视力≥0.5者291眼达82%,脱残339眼(95.5%)脱盲315眼(98.9%)。术后角膜水肿39眼,占10.98%均在3~6天后恢复透明。后囊破裂7眼,占1.97%,前房出血4眼,占1.13%。瞳孔轻度变形10眼,占2.8%,暂时性高眼压4眼,占1.13%。结论在行小切口白内障囊外摘出人工晶体植入时,应用改良后的圈匙娩核并注重粘弹剂应用,就会明显减少并发症,达到良好的效果。
简介:目的:探讨舌状截囊方法在过熟期白内障囊外摘除联合人工晶状体植入术的临床效果。方法:对380眼过熟期白内障囊外摘除联合人工晶状体植入术中采用舌状截囊方法,术后观察及随访其疗效。结果:所有患眼术后视力均有不同程度提高,视力恢复情况:术后1d,0.1以下85眼(22.4%),0.1-0.3者162眼(42.6%),0.4-0.6者87眼(22.9%),0.6以上者46眼(12.1%)。术后1mo0.1以下33眼(8.7%),0.1-0.3者152眼(40.0%),0.4-0.6者117眼(30.8%),0.6以上者78眼(20.5%)。术中术后并发症:术中悬韧带断离16眼(4.2%),后囊膜破裂25眼(6.6%),角膜水肿53眼(13.9%),人工晶状体偏位12眼(3.2%)。结论:舌状截囊方法容易掌握,手术的安全性更好,更适合在援非过熟期白内障囊外摘除联合人工晶状体植入术中的应用。
简介:目的观察泪道探通后氟尿嘧啶应用联合鼻泪管中逆行植入球头硅胶管术治疗慢性泪囊炎的临床疗效。方法从门诊就诊的泪道阻塞患者中,选取泪点泪小管均通畅的慢性泪囊炎患者42例(56只眼),随机分为实验组与对照组,治疗组采用先泪道探通扩张,并将氟尿嘧啶溶液浸入阻塞创面,后经鼻腔逆行植入球头硅胶管术治疗,对手术疗效进行分析。对照组则不采用氟尿嘧啶干预措施,其余治疗与对照组相同。两组患者均于术后3个月拔管。结果拔管后随访3~12个月,治疗组21例(29只眼)中有效25只眼,泪道冲洗通畅无分泌物,2只眼冲洗欠通畅无分泌物,2眼泪道冲洗仍阻塞,治愈率86.2%。对照组21例(27只眼)中有效17只眼,泪道冲洗通畅无分泌物,4只眼冲洗欠通畅无分泌物,6眼泪道冲洗仍阻2塞,治愈率63.0%。经χ检验治疗组治愈率高于对照组(P〈0.05)。结论泪道探通联合球头硅胶管逆行植入术治疗慢性泪囊炎具有操作简便、不切皮肤、不损伤组织结构等优点,临床疗效肯定。氟尿嘧啶对于预防泪道阻塞部位创面再次粘连,提高远期疗效有确切作用。
