The overnight corneal swelling of nine subjects was measured with an electronic digital pachometer. Corneal thickness measurements were taken just before eye closure and after seven hours of sleep. Post-sleep recovery to original corneal thickness was followed. Results showed overnight corneal swelling to be about 4 1/2% with logarithmic recovery to baseline within the first hour after eye opening. Considerable variability in the magnitude of overnight swelling among human corneas was indicated. A review of current theories on the cause of overnight corneal swelling is also included.
用电子数字角膜厚度测量仪测量了9名受试者的夜间角膜肿胀情况。在闭眼之前和睡眠7小时后进行角膜厚度测量。跟踪睡眠后角膜厚度恢复到原始厚度的情况。结果显示夜间角膜肿胀约为4.5%，睁眼后第一小时内呈对数恢复至基线。结果表明人眼角膜夜间肿胀程度存在相当大的变异性。本文还对目前关于夜间角膜肿胀原因的理论进行了综述。
