The cornea and methods for measuring intraocular pressure

Introduction: The study aimed to assert the relationship between central corneal thickness (CCT) and intraocular pressure (IOP) measured by: Goldmann applanation tonometry (GAT) Dynamic contour (DCT). Materials Methods: included 150 patients with a mean age of 59.39 ± 13.12 years. Patients were divided into three groups: 50 primary open-angle glaucoma (POAG) patients, ocular hypertension (OHT) normal tension (NTG) patients. IOP was determined using GAT DCT. CCT by ultrasound pachymetry. Results: DCT higher than (19.80 3.67 mmHg vs 17.71 3.35 mmHg). A significant positive association found in all (r = 0.867, p < 0.01). significantly POAG 0.855, <0.01), OHT 0.826, 0.01), NTG 0.832, 0.01) found. correlation 0.198, as well There no neither nor separately patient groups (p > 0.05). Conclusion: CCT-influenced both methods, can not replace GAT, but it is very useful, especially cases where errors are measurement.
