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。 Objective: To investigate the relationship between corneal astigmatism and different degree of myopia in 30 ~ 39 years old population in Hubei Province, and to find out the change rule. Methods: 786 cases of myopia from 30 to 39 years old in Hubei Province were randomly selected. Corneal map and comprehensive refraction table were used to determine the degree of astigmatism, axial and myopia, and the changes were analyzed. Results: Among 30 ~ 39-year-old residents in Hubei Province, the proportion of astigmatism in each myopia ranged from 25 ° to 150 °, and the number of astigmatism astigmatism was higher in all myopia segments. The female myopia segment is about 74.2%, the moderate myopia segment is about 77.3%, the low myopia segment is about 82.9%, the male myopia segment is about 84.6%, the moderate myopia segment is about 80.1%, the low myopia segment About 81.1%. There was no significant difference in the proportion of astigmatism between myopia and males in 30-39 years old. The overall compliance rate of asymptomatic women aged 30 ~ 39 was higher than that of males. There was no significant difference in the proportion of astigmatism between 0 ° ~ 200 ° in myopia of men and women aged 30 ~ 39 years. Conclusion: Among 30 ~ 39-year-old residents in Hubei Province, the proportion of myopic astigmatism in the range of 25 ° ~ 150 ° is the largest, and the number of astigmatism is higher in both myopia and men than in the inverse astigmatism. The proportion of asymptomatic astigmatism in the overall female group was higher than that of the male overall group.
