<i>This article describes the effect of central corneal thickness (CCT) on intraocular pressure (IOP) measurements. CCT is known to affect applanation tonometry readings thus resulting in late glaucoma diagnosis and inadequate IOP-lowering treatment. In patients with thick cornea, ignoring of this parameter will lead to overdiagnosis and unreasonable therapies. In patients with thin cornea, “understated” IOP levels will lead to late glaucoma diagnosis and incorrect management. Data on CCT as a risk factor for glaucoma development and progression are addressed. The article discusses the effect of CCT on the readings of various methods of tonometry. In advanced glaucoma, CCT significantly reduces, as a result, the proportion of thin corneas increases as compared with early glaucoma. Practical need to measure CCT in the course of standard ocular examination is highlighted. However, until recently, the standards of IOP re-calculation adjusted for CCT are not deter mined yet thus requiring further studies.</i>
