All examinations and measurements were done by the same 2 personnel. A thorough examination was done and IOP was measured in all subjects using iCare Ta01 tonometer and the Goldmann's applanation tonometer 3 times each and the average was taken. Materials and Methods: Intraocular pressure measurements were obtained in 440 eyes of 220 subjects in which 320 were normal eyes and 120 eyes had a high IOP. Purpose: To compare the readings of the Goldmann's applanation tonometry with that of the iCare Ta01i in Indian patients. Readings obtained were compared between instruments and with central corneal thickness and radius of curvature. Methods: IOP was measured on 115 eyes in a group of Polish children, aged between 5–17 years (mean ± standard deviation 11.3 ± 3.0 years) using three different tonometers: non-contact (NCT), the ICare and Goldmann applanation (GAT). In addition, the study adds to the relatively small body of literature on IOP in the growing eye which will collectively allow trends to be identified and ultimately norms to be established. The aim of this study was to undertake a comparative analysis of three different tonometers on a group of healthy children to see whether differences exist and whether these may be related to central corneal thickness and/or radius of curvature. Measurements are needed on many cohorts of children with different tonometers to determine how the values correlate between instruments, whether corneal parameters affect readings and whether correlations between age and IOP values can be discerned. There was a high concordance between the IOP readings obtained by the three devices: a strong and significant correlation was found between GAT and PDCT (r = 0.94, P < 0.001) GAT and iCare (r = 0.86, P < 0.001) and iCare with PDCT (r = 0.81, P < 0.001).īackground: Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Twenty eyes of 20 patients (mean age 74.3 ± 14.4, 14 females) post-DSAEK were included in this study. Effects of keratometry, central, thickness (CCT), endothelial cell density (ECD) and axial length on IOP measurements were assessed with Pearson's correlation. Agreement between measurements was calculated with correlation analysis and Bland-Altman plots. We compared IOP values measured by the Goldmann tonometry (GAT), iCare rebound tonometry (iCare) and Pascal dynamic contour tonometry (PDCT) in eyes following DSAEK. The current study compares different devices in assessing post-DSAEK intraocular pressure (IOP). Corneal thickness inevitably increases following Descemet's stripping automated endothelial keratoplasty (DSAEK), owing to the addition of a donor graft.
