Abstract |
PURPOSE To compare Icare rebound tonometer (IRT) and Goldmann applanation tonometer (GAT) and investigate the clinical usefulness of IRT. METHODS: In a retrospective study of 131 eyes with glaucoma and glaucoma suspect, intraocular pressure (IOP) was measured with IRT and GAT. The correlation between IRT and GAT and the influence of refractive error (spherical equivalent; SE) and central corneal thickness (CCT) were analyzed. RESULTS: A distinct correlation between IRT and GAT was found. IOP measured with GAT was 2.23 +/- 3.16 mm Hg higher than with IRT (p < 0.001). As CCT increased, IOP was measured higher with both GAT and IRT. IOP in myopic eyes (SE > or = -5 diopter) was measured relatively lower than in hyperopic eyes (SE < -5 diopter) with GAT (+1.50 +/- 0.68 mm Hg) and IRT (+1.88 +/- 0.75 mm Hg). CONCLUSIONS: IRT showed strong correlation with GAT, but IOP measured approximately 2 mm Hg lower. The IOP tends to measure lower at low CCT and in myopic eyes. |
