通过对３８４名屈光不正儿童进行睫状肌麻痹下视网膜检影验光，角膜散光测定和视盘形态观察，分析了散光与视盘形态的关系。随散光度数增加，圆形视盘减少，竖椭圆形和斜椭圆形视盘增加，视盘变狭长；散光程度依次为：斜椭圆视盘组＞竖椭圆视盘组＞圆形视盘组。探讨了散光形成的原因。提示对视盘形态异常儿童早期验光的重要性。 384 patients with ametropia under cycloplegic retinal retinal optometry, corneal astigmatism and optic disc morphology observed, the relationship between astigmatism and optic disc morphology was analyzed. As the degree of astigmatism increased, the number of discs decreased, the number of vertical oval and oblique oval discs increased, and the length of astigmatism changed. The degrees of astigmatism were as follows: oblique oval disc group> vertical oval disc group> circular disc group. The causes of astigmatism were discussed. Prompted the importance of early optometry in children with abnormal optic disc morphology.
