6～14岁学生近视程度与角膜曲率、眼轴、身高、体质量及骨龄的关系

Relationship between the corneal curvature, axial length, height, weight, bone age and the degree of myopia in students aged 6-14

摘要:

目的：了解6～14岁学生近视程度与身高、体质量、角膜曲率、眼轴及骨龄之间的关系。 方法：对上海市宝山区6～14岁学生进行身高、体质量、视力普查，621例视力低下的学生予以复方托吡卡胺扩瞳验光，测量角膜曲率度数和眼轴长度，行双手腕骨X线摄片测定骨龄，对检查结果予以整理，分析参数之间的关系。 结果：等效球镜度数与眼轴长度负相关，与角膜曲率无关。等效球镜度数与年龄负相关，眼轴长度、身高、体质量、骨龄差与年龄正相关，角膜曲率和眼轴差与年龄不相关。身高、体质量、年龄、骨龄、骨龄差与等效球镜度数负相关，与眼轴长度正相关，与角膜曲率无关。身高、体质量、年龄、骨龄均与眼轴差无关，而骨龄差与眼轴差弱正相关。 结论：青少年近视与全身生长发育的节奏存在一定的关系。

Abstract:

AIM：To explore the relationship between the corneal curvature, axial length, height, weight, bone age and the degree of myopia in students aged 6-14. METHODS：The height, weight, visual acuity were examined in children aged 6-14 in Baoshan district of Shanghai. There were 621 poor vision students were enrolled refractive examination, including the optometry after cycloplegia, corneal curvature and axial length.They were also taken the imaging examination of carpal bone to define their bone age. The relationship of examination results was analyzed. RESULTS: Statistics showed that the spherical equivalent had negative correlation with axial length and had no correlation with corneal curvature. The spherical equivalent had negative correlation with age, the axial length, height, weight, bone age had positive correlation with age, while the corneal curvature and the difference of axial length between measurement and emmetropia had no correlation with age. The height, weight, age, bone age and bone age difference had negative correlation with spherical equivalent, had positive correlation with axial length, had no correlation with corneal curvature. The height, weight, age, bone age had no correlation with the difference of axial length, and the bone age difference had weak positive correlation with the difference of axial length. CONCLUSION: The myopia of adolescent has some relationship with the rhythm of body growth and development.
