Abstract

Myopia, as characterized by a large refractive error (e.g. -10.7 +/- 0.4 D), was induced in post-hatch chicks by a 14 day application of a goggle that was designed to blur the retinal image. In comparison to untreated eyes, the treated eye showed significant changes in wet eye weight and both axial and equatorial lengths. However, the lenses of myopic and non-myopic eyes were not significantly different in focal characteristics, light transmittance or total soluble protein content. Thus the lens neither contributes to, nor compensates for the large refractive error observed in experimentally induced myopia.

摘要

通过给孵化后的雏鸡佩戴旨在使视网膜图像模糊的护目镜14天，诱发其近视，其特征为屈光不正较大（例如-10.7 +/- 0.4 D）。与未处理的眼睛相比，处理过的眼睛在湿眼重量以及眼轴长度和赤道长度方面均出现了显著变化。然而，近视和非近视眼睛的晶状体在焦点特性、透光率或总可溶性蛋白含量方面并无显著差异。因此，晶状体既不会导致实验性诱导近视中观察到的较大屈光不正，也不会对其起到补偿作用。
