UNLABELLED: The purpose of the study was to determine the dependence of intraocular pressure (IOP) measured by Goldmann applanation tonometer (AT), non-contact tonometer (BT) and Tone-Pen (TP) on central corneal thickness (CCT) as well as the respective comparison in relation to the central corneal thickness. METHODS: CCT and IOP were assessed in 106 eyes of 106 subjects aged 7-77 years (mean 34.3 +/- 17.1 years). IOP was measured with BT, TP and AT. Central corneal thickness was assessed using ultrasound pachymetry. The obtained data were statistically analyzed. RESULTS: The mean CCT in 106 eyes was 572 +/- 46 microm (range 455-701 microm). A positive correlation between IOP and CCT was found in all types of tonometry. The change in measured IOP for a 100 microm of CCT was 2.0, 2.5 and 5.6 mmHg for TP, AT and BT, respectively. CONCLUSION: IOP measurement by all three methods is affected by CCT. The BT is influenced by CCT significantly more than are AT and TP.
