目的探讨中老年人散光的特点和诊治方法。方法对４０～７５岁散光患者１４１例（２７４眼）进行临床分析，门诊屈光不正患者，检影验光及角膜曲率计检查。结果远视性散光多（８０．７％），反规性散光多（７５．６％），反规性散光随年龄增加而增多。结论这种变化与角膜的屈光力改变有关；扩瞳检影、配合角膜曲率计检查，更能准确地确定散光的度数与轴位。
Objective To investigate the characteristics and diagnosis and treatment of astigmatism in the elderly. Methods A total of 141 patients (274 eyes) with astigmatism at 40-75 years old were included in the study. Outpatients with refractive ametropia, retinoscopy and corneal curvature were examined. Results Hyperopic astigmatism (80.7%), anti-regulatory astigmatism (75.6%), anti-regulatory astigmatism increased with age. Conclusion This change is related to the corneal refractive power changes; dilation retinoscopy, with corneal curvature check, more accurately determine the degree of astigmatism and axial position.
