Although investigations of human refractive error development and normal ocular growth have been conducted for the last 50 years, no previous study of refractive error and the ocular components has measured all the ocular components.
The Orinda Longitudinal Study of Myopia was initiated to characterize the development of refractive error and normal eye growth in a sample of predominantly Caucasian children ages 6 to 14 years.
Cross-sectional results from 530 children ages 5 to 12 years in the 1st, 3rd, and 6th grades are presented.
This sample's refractive error decreased toward emmetropia with age from an average of +0.73 D at age 6 years to an average of +0.50 D by age 12 years. Between the ages of 6 and 12 years, the vitreous chamber elongated (by 0.52 mm) and the crystalline lens power decreased (by 1.35 D); surprisingly, the crystalline lens thinned by 0.14 mm during this same time period.
尽管在过去50年里人们对人类屈光不正的发展和正常眼生长进行了研究，但此前关于屈光不正和眼内各组成部分的研究均未对所有眼内组成部分进行测量。
发起了奥林达近视纵向研究，以描述6至14岁以白种人为主的儿童样本中屈光不正的发展和正常眼生长情况。
呈现了来自一、三、六年级的530名5至12岁儿童的横断面研究结果。
该样本的屈光不正随着年龄增长向正视化发展，从6岁时平均+0.73 D降至12岁时平均+0.50 D。在6至12岁之间，玻璃体腔拉长（0.52毫米），晶状体屈光力下降（1.35 D）；令人惊讶的是，在此期间晶状体变薄了0.14毫米。
