为探讨散光眼散光轴向分布的规律，本文对５８２例（１０１８眼）散光眼进行了分析。通过验光检查确定散光轴向，并按年龄大小分成七个年龄组，就近视性散光、远视性散光和混合性散光之轴向分别加以分析。结果：散光轴向的总体分布以垂直经线和水平经线为多。无论何种散光类型，４０岁以下各年龄组散光眼的散光轴向大多呈顺规性散光分布。随着年龄的增长，逆规性散光的比例增高，４０岁以上年龄组散光眼的散光轴向大多呈逆规性散光分布。各年龄组之间散光轴向差异极显著。双眼散光轴向大多呈对称性或同轴性分布。结论：散光轴向可随年龄增长而改变，并呈逆规性散光状态的变化。
In order to explore the axial distribution of astigmatism astigmatism, 582 cases (1018 eyes) of astigmatism were analyzed. The axial astigmatism was determined by optometry and divided into seven age groups by age and analyzed separately for axial astigmatism, hyperopic astigmatism and mixed astigmatism. Results: The axial distribution of astigmatism with vertical warp and horizontal warp more. Regardless of the type of astigmatism, astigmatic axial astigmatism in all age groups under 40 years of age were mostly astigmatic astigmatism distribution. With age, the proportion of asymptomatic astigmatism increased, astigmatism in the age group over the age of 40 most of the astigmatic axial astigmatic astigmatism distribution. Axial differences in axial astigmatism were significant among all age groups. Most of the axial astigmatism symmetry or coaxial distribution. Conclusion: Axial astigmatism can change with age, and showed the changes of astigmatism.
