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:今天,我们在这里召开2005年全国防盲工作研讨会。这次会议的主要内容是:分析全国防盲工作面临的形势和挑战,研究开展防盲工作的重点和策略;研究制定2006-2010年全国防盲工作规划。同时,还要对“视觉第一中国行动”二期启动以来的工作进行总结,对中期评估事宜和下一步工作进行部署。两天的时间,任务还是比较重的,我希望大家借此机会,广泛交流各地防盲治盲工作情况,借鉴各地有益的工作经验,在充分研讨,制定出我国2006-2010年防盲工作规划的同时,研究探索适合我国国情、进一步推进我国防盲治盲工作的政策措施、有效途径。
