Corneal Thickness in an Ophthalmologically Normal Japanese Population

Using optical pachymetry, CCT in normal Japanese persons was defined as 517.5±29.8 μm. Men had greater CCT measurements than women. The CCT measurements positively correlated with IOP and corneal radius and negatively correlated with age and refraction in men. Intraocular pressure positively correlated with CCT, regardless of age.
