WebApplanation tonometry has been the gold standard for determining IOP for almost 50 years. This approach is less likely to be influenced by variables such as scleral rigidity, which can significantly affect measured values obtained by Schiotz tonometry. 1 Goldmann discussed the influence of variations in central corneal thickness (CCT) on IOP ... WebIOP was measured with RBT which averages 6 readings followed by Goldmann applanation tonometry (GAT). Central corneal thickness (CCT) was obtained by ultrasound pachymetry with an average of 5 consecutive readings.
