title: Caucasian emmetropic aged subjects have reduced corneal thickness values: emmetropia, CCT and age.
abstract: We aimed to analyze the possible changes in corneal thickness values according to age in emmetropic subjects. The central corneal thickness values of 100 emmetropic subjects (n = 100) were analyzed with the DGH 2000 AP ultrasonic pachymeter (DGH Technology, Inc., San Diego, CA, USA) by one experienced physician. The mean age of the subjects was 40.6 +/- 12.1 years old (range, 21-64). Analysis of the central corneal thickness (CCT) values by age subgroups indicated that subjects aged between 20 and 30 years had the higher CCT values. Differences in CCT values between the age groups were significant (p < 0.001; 1-way ANOVA test). A significant correlation between CCT values and age was found (r = -0.974; p < 0.001). In sum, it seems that there is a decrease in CCT values with age in emmetropic subjects.
