70 children 140 eyes with astigmatic refractive error were reported. The methods of examination included retinoscopy, autorefraction and keratometry. The data of eye astigmatism and keratic astigmatism measured by the methods were analyzed. It revealed that there existed a good identity among the three methods, and the relationship between eye astigmatism (EAs) and keratic astigmatism (KAs) shown by the formula EAs = 0.94 KAs - 0.13 was similar to that of previous reports. It is suggested that the keratometry be necessary as an assistant method of refraction to assure to get a reliable astigmatism result for children.
报告了70例患有散光屈光不正的儿童共140只眼。检查方法包括检影验光、自动验光和角膜曲率测量。对通过这些方法测量的眼散光和角膜散光数据进行了分析。结果显示这三种方法之间存在良好的一致性，并且通过公式EAs = 0.94KAs - 0.13所示的眼散光（EAs）与角膜散光（KAs）之间的关系与先前报告相似。建议将角膜曲率测量作为屈光检查的辅助方法，以确保获得儿童可靠的散光结果。
