目的:对湖北地区17～19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:对随机抽取的762例湖北地区17～19岁居民进行散光度、轴向及近视度数的测定,并分析其变化规律。结果:湖北地区17～19岁居民中,各个近视度段散光在25°～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70.1%,中度近视段约为78.6%,低度近视段约为83·8%;男性高度近视段约为64.7%,中度近视段约为73.8%,低度近视段约为82.3%。17～19岁男性及女性中各近视度段顺规散光人数比例差异没有统计学意义。17～19岁男性低度近视段者0°～200°散光比例高于其他两组,差异有统计学意义,且有随近视度数增高,0°～200°散光人数所占比例有减低趋势;女性高度近视段在0°～200°散光人数比例低于其它两组,差异有统计学意义。结论:湖北地区17～19岁居民中,各个近视度段散光在25°～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;男性低度近视段在0°～200°散光比例高于其它两组;女性高度近视段0°～200°散光人数比例低于其它两组。

AIM:To determine the prevalence and development of astigmatism in 17-19 Years people in Hubei and to find out the relationship and the rules of change between astigmatism and the different myopic degree. METHODS: Totally 762 cases of 17-19 years old people in Hubei randomly selected were determined the diopters and axes of astigmatism and myopic degree. RESULTS: The account of 25-150 degree astigmatism range in the dweller of Hubei area 17-19 years people in each myopic degree section was the largest. The number of men’s and woman’s group high myopia section was about 64.7%/70.1% and moderate myopia section was about 73.8%/78.6% and low-degree myopia section was about 82.3%/83.8%. The difference between 17-19 years old men and women in each myopic degree group with the rule astigmatism percentage was not statistically significant. 17-19 years old men’s within 200 astigmatism percentage in low-degree myopic group was higher than the other two groups. Women’s within 200 astigmatism percentage in high-degree myopic group was lower than the other two groups. The differences were statistically significant.CONCLUSION:The account of 25-150 degree astigmatism range in the dweller of Hubei area 17-19 years people in each myopic degree section was the largest. 17-19 years old men’s within 200 astigmatism percentage in low-degree myopic group is higher than the other two groups. Women’s within 200 astigmatism percentage in high-degree myopic group is lower than the other two groups.
