  • 简介:目的评价带线羟基磷灰石义眼座(HA)无包裹植入的临床疗效.方法对29例眼球摘除术后患者,采用带线羟基磷灰石义眼座作为眼窝植入物,无包裹直接植入.Ⅰ期植入21例.Ⅱ期植入8例.结果分别随访5-18月,4眼术后出现球结膜裂开,2眼术后轻度上睑下垂,1眼术后五月义眼座中度暴露,均经相应治疗后恢复.其他病例手术效果良好,无植入物脱出及移位,义眼座活动度良好.结论带线羟基磷灰石义眼座直接植入术,具有操作简单、材料易得、并发症少等优点,具有良好的应用前景.

  • 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。
