Abstract

To investigate the relationship of the density change of lens nucleus and cortex with anterior chamber depth and lens thickness, we measured the anterior chamber depth, density and length of lens nucleus and cortex of 312 eyes with a Scheimpflug camera. The mean values of density of lens nucleus and cortex were 108.45+/-46.33CCT and 27.74+/-13.76CCT, respectively. The mean values of the thickness for both were 2.85+/-0.54mm and 1.29+/-0.46mm, respectively. The mean value of anterior chamber depth was 2.93+/-0.49mm. The densities of lens nucleus and cortex were increased significantly with aging, but lens thickness and anterior chamber depth were decreased. The value of anterior chamber depth changes and lens thickness changes were more rapid especially in the 5th and 7th decades compared with other groups(P<0.01), and more rapaid in the density group(100~150CCT) than other group in changing densities(P<0.05), and they were highly correlated with anterior cortex, posterior cortex, nucleus in order at each portion of lens. Both anterior chamber depth changes and lens thickness changes were more rapid in the lens cortex than those in the lens nucleus.
