目的:对湖北地区30～39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786例湖北地区30～39岁近视人群,应用角膜地图、综合验光台进行散光度、轴向及近视度数的测定,并分析其变化规律。结果:湖北地区30～39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74.2%,中度近视段约为77.3%,低度近视段约为82.9%;男性高度近视段约为84.6%,中度近视段约为80.1%,低度近视段约为81.1%。30～39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。30～39岁女性总体顺规散光人数比例高于男性总体。30～39岁男性及女性近视度各组0°～200°散光人数比例之间差异没有统计学意义。结论:湖北地区30～39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。女性总体组顺规散光人数比例高于男性总体组。

AIM:To determine the prevalence and development of astigmatism in 30-39 years old people in Hubei and find out the relationship between its change rule and different myopic degree.METHODS:A total of 786 patients(30-39 years old)were randomly selected in Hubei and the relationship between the diopters and axes of astigmatism was analzed.RESULTS:Among the 30-39 years old dwellers in the Hubei area,astigmatism of 25-150 degree in each myopic degree section accounted for the largest percentage,in high myopia section of male group,it accounted for about 84.6%,in moderate myopia section about 80.1%,in low-degree myopia section about 81.1%;in high myopia section of female group,it accounted for about 74.2%,in moderate myopia section about 77.3%,in low-degree myopia section approximately 82.9%.The difference between 30-39 year-old men and women in each myopic degree group with the rule astigmatism percentage was not statistically significant.30-39 year-old women’s total with the rule astigmatism percentage was higher than men overall.The difference between 30-39 year-old men’s and women’s each myopic degree groups with 0-200 astigmatism percentage was not statistically significant.CONCLUSION:Among 30-39 years old dwellers in Hubei area,astigmatism in 25-150 degree accounts for the largest percentage in each myopic degree section.30-39 year-old women’s total with the rule astigmatism percentage is higher than men overall.
