Purpose
The aim of this study was to determine the central corneal thickness ( CCT) of healthy Saudi
children aged 7–12 years and investigate variations in CCT according to age and sex.
Patients and methods
In this prospective study, one eye was analyzed from each of 412 healthy children. The CCT
was measured using a noncontact Nidek CEM 530 specular microscope. A regression analysis
was carried out to determine the relationship between CCT and age, and an unpaired t-test
was used to compare fi ndings between the sexes; CCT percentiles were then calculated for
each age.
Results
The median CCT among all participants was 576 μm. Regression analysis detected a strong
positive correlation between CCT and age (r = 0.64, P < 0.0001), and CCT was found to
increase by 8.26 μm each year. The mean CCT of boys was 0.45 μm thicker than that of girls,
but this difference was not statistically signifi cant (P = 0.83).
Conclusion
The CCT increased with age fro m 7 to 12 years, and there was no statistically signifi cant
difference in the CCT of boys and girls.
