目的了解青少年近视眼的发生与发展的形态学改变，为有效防治提供科学数据。方法对昆明地区３～１８岁儿童、青少年抽样１００８人，使用角膜曲率计、眼Ａ超声波仪作眼球活体生物测量，红外自动屈光检测仪作屈光检测及常规眼部综合检查，所测数据经ＳＰＳＳ／ＰＧ＋软件包统计分析。结果青少年中屈光异常以近视为主，随年龄增加及学龄增高近视增多。讨论青少年在生长发育过程中，眼球结构变化最大的是眼轴，是形成近视的主要结构变化，近视程度与眼轴长度呈正相关，与前房深度和晶体厚度及眼球前／后节比值有一定关系，与角膜屈光力无明显关系。
Objective To understand the morphological changes of the occurrence and development of juvenile myopia and provide scientific data for effective prevention and treatment. Methods A total of 1008 children and adolescents were enrolled in this study. 1008 children and adolescents were enrolled in this study. The corneal curvature meter and ocular A ultrasonic instrument were used to measure the biological activity of the eyeballs. The refractive index of the infrared autorefractometer was measured by conventional ophthalmic examination. SPSS / PG + software package statistical analysis. Results The majority of refractive errors in adolescents with myopia, with age and increased school age increased myopia. Discussion of adolescents in the process of growth and development, the ocular axis is the most significant change in the structure of the eye is the main structural changes in the formation of myopia, myopia and axial length was positively correlated with the depth of the anterior chamber and the thickness of the anterior lens and eye / Relationship, and corneal refractive power no significant relationship.
