UNLABELLED: The purpose of the study was to compare the levels of the intraocular pressure (NOT) measured in one eye at the same moment by three different methods: by Goldmann applanation tonometer (AT), non-contact tonometer (BT) and Tono-Pen (TP). It was further set the average variability of the performed measurements for particular tonometric methods. METHODS: NOT was assessed in 106 eyes of 106 subjects aged 7-77 years (average 34.3 +/- 17.1 years). NOT was measured at the same moment with BT, TP and AT. The obtained data were statistically analyzed. RESULTS: The average NOT was 16.55 +/- 2.95, 17.95 +/- 4.47 and 16.13 +/- 3.4 mmHg when AT, BT and TP were applied. Average variability of three measurements for AT, BT and TP was 1.51 +/- 0.96, 1.78 +/- 1.08 and 1.47 +/- 0.9 mmHg. Average NOT levels of the measured AT and TP were almost identical with a difference of 0.42 mmHg (p = 0.236). Average level of the intraocular pressure measured by BT was higher by 1.40 mmHg and 1.82 mmHg in comparison with AT and TP (p = 0.00002), respectively. CONCLUSION: NOT measurement produced almost identical average levels at AT and TP, whereas at BT the levels were much higher. Average variability of the three subsequent NOT measurements was the highest at BT, whereas at AT and TP the average variability was lower and nearly identical.

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.
