眼外形如眼球突出度、瞳距、和内眦距离等各有其正常值,并具有民族差异性;眼内结构如眼轴长度、前房深度、晶状体厚度和玻璃体厚度亦各有其正常值,并在近视眼患者中发生相应的改变。现将眼外形及眼内结构正常值的生物学测量及其临床意义作一简要综述。一、眼外形的生物学测量及 Eye contour, such as eyeball protrusion, interpital distance, and internal 眦 distance have their normal values, and have national differences; intraocular structures such as axial length, anterior chamber depth, lens thickness and vitreous thickness also have their normal values , And the corresponding changes in patients with myopia. The eye shape and intraocular structure of the normal biological measurements and its clinical significance of a brief review. First, the biological appearance of the eye shape measurement
