简介:目的:对湖北地区20~29岁人群的角膜散光情况与不同近视度数的关系进行调查,找出其变化规律。方法:用角膜地形图对随机抽取的2254例湖北地区20~29岁青年居民进行散光度、轴向及近视度数的测定,并分析其变化规律。结果:湖北地区20~29岁居民中,各个近视度段散光在26°~150°范围内所占人数比例最大,各个近视度段均呈现顺规散光人数多于逆规散光。其中女性高度近视段约为75.3%,中度近视段约为82.7%,低度近视段约为87.2%;男性高度近视段约为74.6%,中度近视段约为83.0%,低度近视段约为82.3%。20~29岁男性高度近视段顺规散光人数比例高于其他两组;女性低度近视段顺规散光人数比例低于其他两组,差异有统计学意义。20~29岁人群中女性中度近视段顺规散光人数比例高于同近视度男性组,且女性总体组顺规散光人数比例高于男性总体组,差异有统计学意义。20~29岁男、女性高度近视组200°以内散光人数比例均低于中度近视组,差异有统计学意义。结论:湖北地区20~29岁居民中,各个近视度段散光在26°~150°范围内所占人数比例最大,且各个近视度段不论男女均呈现顺规散光人数多于逆规散光;男性高度近视段顺规散光人数比例高于其他两组,女性低度近视段顺规散光人数比例低于其他两组;女性中度近视段顺规散光人数比例高于同近视度男性组,且女性总体组顺规散光人数比例高于男性总体组;男、女性高度近视组200°以内散光人数比例均低于中度近视组。
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。
