利用A超、角膜地形图仪测定上述患者的角膜中央厚度、角膜中央屈光力及眼轴长度。
To measure central corneal thickness, central corneal diopter and eye axis with ultrasonic A and corneal topography.
目的：测量一先天性无虹膜家系患者的中央角膜厚度，分析可能的原因。
Objective: To measure the central corneal thickness(CCT) of a family with congenital aniridia and analyze its reason.
结论：先天性无虹膜患者的中央角膜厚度明显增加，中央角膜厚度的增加与角膜内皮细胞无关；
Specular microscope shows normal corneal endothelial cells. Conclusion : The CCT of a family with congenital aniridia thickens clearly. Corneal endothelial cells are not responsible for it.
结论：影响近视眼患者角膜中央厚度的主要因素是：配戴角膜接触镜史、屈光度数和眼压。
CONCLUSION: The CCT in patients of myopia was correlated with history of wearing soft contact lens, refraction and IOP.
