This paper investigates the amplitude of accommodation of early onset myopes, late onset myopes, emmetropes, and hyperopes. Eighty subjects were used, 41 women and 39 men, with an age range of 18-22 yr (mean = 19.82). All subjects wore an optimum refractive correction, giving visual acuities of 20/20 or better. Significant differences were found between the four refractive groups, with late onset myopes having the largest amplitude of accommodation, followed by early onset myopes, emmetropes, and hyperopes. The results are discussed in the light of previous findings on tonic accommodation and the accommodative response gradient and interpretated in the context of a dual innervation to the ciliary muscle.
本文研究早发性近视、迟发性近视、正视眼和远视眼的调节幅度。研究使用了80名受试者，41名女性和39名男性，年龄范围为18 - 22岁（平均 = 19.82岁）。所有受试者均佩戴最佳屈光矫正镜片，视力达到20/20或更好。在四个屈光组之间发现了显著差异，迟发性近视的调节幅度最大，其次是早发性近视、正视眼和远视眼。根据先前关于张力性调节和调节反应梯度的研究结果对这些结果进行了讨论，并在睫状肌双重神经支配的背景下进行了解释。
