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:目的分析常年性变应性鼻炎的狗、猫上皮变应原皮肤点刺试验的阳性结果,对其他气传变应原的反应性,并进一步探讨环境接触与其相关性。方法总结1022例常年性变应性鼻炎患者采用阿罗格叶7种气传变应原标准化试液进行的皮肤点刺试验;分析狗、猫上皮变应原的皮试结果及合并其他气传变应原阳性的比例;并根据是否有环境接触分类,比较各组在阳性率分布上的差异。结果常年性变应性鼻炎中狗上皮变应原皮试阳性占13.80%,猫上皮阳性占6.95%;且98%以上合并其他气传变应原阳性,尤以合并粉尘螨、屋尘螨阳性居多。其中21.93%和26.32%环境接触狗/猫的变应性鼻炎相应狗/猫上皮变应原皮试阳性;无环境接触组的阳性率分别为12.78%和6.58%,差异均有统计学意义(P〈0.01)。结论常年性变应性鼻炎的狗上皮及猫上皮的阳性率位居前列,其中绝大多数合并其他气传变应原阳性。鉴于环境接触对狗、猫上皮过敏的高危险性,变应性鼻炎患者应该尽可能地避免饲养、接触宠物。
