目的:对湖北地区30～39岁人群的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948例湖北地区30～39岁居民进行散光度数、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75.6%,中度近视段约为70.0%,低度近视段约为66.0%;男性高度近视段约为76.4%,中度近视段约为71.0%,低度近视段约为70.0%。30～39岁男性低度近视组顺规散光人数比例低于其他两组;女性低度近视组顺规散光人数比例低于高度近视度组,且女性总体组顺规散光人数比例高于男性总体组,以上差异有统计学意义(P<0.05)。30～39岁男性及女性近视度各组200°以内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。30～39岁男性低度近视组顺规散光人数比例低于其他两组;女性低度近视组顺规散光人数比例低于高度近视度组,且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 astigmatism and different myopic degree.METHODS:The diopters and axes of astigmatism in 948 randomly selected 30-39 years people in Hubei were determined.RESULTS:In Hubei area 30-39 years old dwellers,in each myopic degree section,astigmatism accounted for the largest percentage in 25-150 degrees range,the number of high myopia section in male group was about 76.4%,moderate myopia section about 71.0%,low-degree myopia section about 70.0%.High myopia section in female group was about 75.6%,moderate myopia section about 70.0%,low-degree myopia section approximately 66.0%.30-39 years old men in low-degree myopia group with the rule astigmatism number lower than other two groups.Women in low-degree myopia group with the rule astigmatism number lower than the high myopia group.CONCLUSION:In Hubei area 30-39 years old dwellers,in each myopic degree section,astigmatism in 25-150 degrees range accounts for the largest percentage,30-39 year-old men in low-degree myopia group with the rule astigmatism number lower than other two groups.Women in low-degree myopia group with the rule astigmatism number lower than the high myopia group.
