Corneal thickness and transparency changes were measured following exposure of the cornea to various levels of osmotic stress. Bathing the cornea in hypotonic solutions of NaCl caused an increase in corneal thickness and light scatter within the cornea. Transparency changes with hypotonicity were determined by comparing the relative brightness of haloes around a bright lamp source for the various concentrations of NaCl solutions. Corresponding corneal thickness changes were determined by pachometry. A nearly linear relationship was found between solution hypotonicity and the degree of corneal swelling, whilst an exponential relationship was found between hypotonicity and relative halo brightness. The rate of corneal recovery from osmotic stress was found to be constant with different degrees of tonicity, although the rate of thickness recovery was much slower than the recovery from haloes.
在将角膜暴露于不同程度的渗透压应激后，测量角膜厚度和透明度的变化。将角膜浸泡在NaCl低渗溶液中会导致角膜厚度增加以及角膜内的光散射增加。通过比较不同浓度NaCl溶液中明亮灯源周围光晕的相对亮度来确定低渗引起的透明度变化。通过角膜厚度测量法确定相应的角膜厚度变化。发现溶液低渗度与角膜肿胀程度之间存在近乎线性的关系，而低渗度与相对光晕亮度之间存在指数关系。尽管厚度恢复的速度比光晕恢复的速度慢得多，但发现角膜从渗透压应激中恢复的速度在不同程度的张力下是恒定的。
