| الوصف: | Purpose: 1. To assess the correlation and agreement between Goldmann Applanation Tonometer (GAT) and Ocular Response Analyzer (ORA). 2. To investigate the corneal hysteresis (CH) and the Corneal Resistance factor (CRF) in normal subjects and glaucomatous patients. Methods: Prospective controlled study including one eye at random of 41 normal subjects and 45 glaucoma patients with optic disc alteration and visual field defect. The IOP was determined by GAT and ten minutes later by ORA followed by pachymetry. Corneal‐Compensated Intraocular Pressure (IOPcc), Corneal Resistance Factor (CRF) and CH were considered for analysis. Pearson correlation coefficient and Bland‐Altman plots were used to evaluate the correlation and the agreement between the two devices. Results: The mean CCT was 558±35 μm in normal subjects and 540±38 μm in glaucoma patients. The mean GAT was 17.0±2.5 mmHg for normals and 17.8±6.5 mmHg for glaucoma group. The mean IOPcc was 14.2±3.9 mmHg in normal subjects and 17.5±6.3 mmHg in glaucoma. • The GAT and IOPcc values were correlated in both group (p<0.01). • There was a significant correlation between CCT and CH in all patients (p<0.05). •CH and CRF values were significantly lower in glaucoma group (p<0.05) Conclusions: •The CH and CRF values are significantly lower in glaucoma patients comparing to normal subjects. |
