Corneal thickness and relating factors in a population-based study in Japan: the Tajimi study.
Am J Ophthalmol 2007; 144(1):152-4AJ

Abstract

PURPOSE

To evaluate central corneal thickness (CCT) in a Japanese population and to describe the relationship between CCT and other factors.

DESIGN

Population-based cross-sectional study.

METHODS

Reliable CCT measurements were obtained using specular-type pachymetry from 2,868 persons 40 years or older selected randomly from the population of Tajimi City.

RESULTS

The CCT averaged 0.521 +/- 0.032 mm (mean +/- standard deviation). The CCT was thicker in men than in women (P < .001) and was correlated with age (right eyes only), height, weight, diastolic blood pressure, systolic blood pressure (left eyes only), intraocular pressure (IOP), and corneal curvature (P < .05, the Pearson correlation analyses). Multiple regression analysis showed that only gender, IOP, and corneal curvature were significantly (P < .011) associated with CCT.

CONCLUSIONS

The mean CCT obtained using an optical method in a Japanese population was 0.521 mm. The CCT was associated significantly with gender, IOP, and corneal curvature but not with age in multiple regression analyses.
