OBJECTIVE: To evaluate the influence of corneal thickness (CT) on the intraocular pressure (IOP) measurements, the agreement of IOP readings with I Care rebound tonometer (RBT) and Goldmann applanation tonometer (GAT), and the agreement of central and peripheral IOP values obtained by RBT. METHODS: Thirty-seven eyes of 34 patients after Descemet's stripping with automated endothelium keratoplasty (DSAEK) underwent CT measurement using anterior segment OCT (AS-OCT) followed by IOP evaluation with the GAT at corneal center and with the RBT at corneal center and at 1 mm from the limbus in the nasal and temporal directions. The mean IOP measurement by the RBT and measurement by the GAT were analysed by paired t test. Pearson correlation analysis were performed to assess the correlations between the measurement and the influence of CT on IOP values. Agreement between the tonometers was calculated using the Bland-Altman method. RESULTS: IOP obtained by GAT was (16.2 ± 4.7) mm Hg (1 mm Hg = 0.133 kPa), and IOP obtained from central cornea, nasal cornea and temporal cornea by RBT were (16.0 ± 5.3) mm Hg, (17.4 ± 5.0) mm Hg and (17.1 ± 5.0) mm Hg, respectively. There was no statistical difference between the IOP on central cornea obtained by GAT and RBT (t = 0.77, P = 0.446), IOP on the peripheral cornea were higher than on central cornea by RBT (t = 3.24, 3.17, P = 0.003), and they were positively correlated (r = 0.869, 0.911, P < 0.05). The IOP readings showed positive relationship ...
