Central Corneal Thickness and its Association with Ocular Parameters

Central corneal thickness (CCT) is an important indicator of cornea health. There has been increased interest in CCT because of its influence on intraocular pressure (IOP) measurement. CCT can affect the accuracy of IOP measurement for the diagnosis and management of glaucoma. Glaucoma is a progressive optic neuropathy with several risk factors including IOP and myopia. Myopic eyes are characterized with greater refractive error, flatter corneal curvature and longer axial length. Here, we will review the relationship between CCT and ocular parameters such as refractive error, corneal curvature and axial length.
