Purpose To compare the intraocular pressure ( IOP ) measurements and reproducibility of the new IC are Home ® rebound tonometer ( RT ) with Goldman applanation tonometer. Methods 36 healthy eyes of 36 patients were enrolled. Three IOP measurements were performed with IC are Home by an ophthalmologist ( RT ‐O) then by the patient ( RT ‐P), and with GAT and non‐contact tonometry ( AIR ). All of the subjects underwent an examination including: slit lamp examination, keratometry, and optical measurements of ocular axial length and central corneal thickness. Results Results of mean IOP s were 16.3 ± 4.8 mmHg ( RT ‐O), 16.2 ± 4.7 mmHg ( RT ‐P), 15.1 ± 2.6 mmHg ( GAT ) and 16.0 ± 2.9 mmHg ( AIR ). There was no statistically difference between the 4 methods with random one‐way ANOVA or repeated measures (P = 0.09) and no difference between each couple of methods after Bonferroni correction for multiple comparisons. Correlation between the tonometers were: r = 87.4% between RT ‐O and RT ‐P, r = 63.4% between RT ‐O and GAT and r = 65.0% between RT ‐P and GAT . The intraclass correlation coefficients ( ICC ) were 0.924 for RT ‐O, 0.854 for RT ‐P and 0.887 for GAT . Bland Altman plots showed a good agreement between the different methods. Conclusions IOP measurements with IC are Home by the patient or the ophthalmologist were well correlated to GAT without statistically significant differences. Reproducibility was good and with a good agreement between the differents methods of measures.
