To report the association between amplitude of accommodation and refractive error.
Refractive error and amplitudes of accommodation were measured in 1,148 eyes of 696 patients as part of the Early Treatment Diabetic Retinopathy Study.
Eyes with myopia, defined as those with a refractive error of -0.75 diopter or more, have lower accommodative amplitudes (P = .005). After multivariate logistic regression analysis adjusting for age, occupation, and white race, lower amplitudes of accommodation remained associated with myopia (P = .03).
Eyes with lower amplitudes of accommodation must use more of their accommodative reserve for near work. Myopia may be an adaptation that develops in eyes with reduced accommodative amplitudes.
报告调节幅度与屈光不正之间的关联。
作为糖尿病视网膜病变早期治疗研究的一部分，对696例患者的1148只眼睛进行了屈光不正和调节幅度测量。
近视眼中，定义为屈光不正为-0.75屈光度或更高的眼睛，其调节幅度较低（P = 0.005）。在对年龄、职业和白种人进行多因素逻辑回归分析后，较低的调节幅度仍与近视相关（P = 0.03）。
调节幅度较低的眼睛在进行近距工作时必须更多地使用其调节储备。近视可能是调节幅度降低的眼睛所产生的一种适应性变化。
