Purpose: To investigate the relationship between central corneal thickness and intraocular pressure, measuring central corneal thickness and intraocular pressure.Methods: We measured central corneal thickness and intraocular pressure in 35 subjects (17 keratoconus subjects, 18 control subjects). None of the subjects had ever worn a contact lens. The cornea was anaesthetised using one drop of 0.5 % proparacaine hydrochloride. Central corneal thickness was measured using an optic ultrasonic pachymeter. Intraocular pressure was then measured using a standard Goldmann tonometer. All data were evaluated statistically.Results: In keratoconic and normal cases, central corneal thickness and intraocular pressure were 430.8±46.53 μm, 532.20±17.05 μm, 8.06± 2.13 mm-Hg, 13.67±1.81 mm-Hg, respectively. Differences between keratoconic and normal eyes for both central corneal thickness and intraocular pressure were statistically significant (p<0.05). Conclusion: The results show that an eye with a thinner cornea tends to present with lower intraocular pressure. This disparity is related with diminish corneal elasticity and corneal thickness in keratoconic eyes. Intraocular pressure and corneal thickness were evaluated together in which corneal thickness are increased or decreased.Keywords: Keratoconus, Corneal thickness, Goldmann applanation tonometer, Intraocular pressureTurkiye Klinikleri J Ophthalmol 2002, 11:207-211
