All the independent variable from liner regression analysis were included in the model. Pre-IOP: Pre-Goldman intraocular pressure before antiglaucomatous medications application. Changes in IOPs: changes in Goldman intraocular pressure after antiglaucomatous medications applications. A1V: applanation1 velocity; A1T: applanation1 time; A2T: applanation2 time; Changes in AV: changes in A1V-A2V after anti glaucomatous medications applications; Changes in AT: changes in A1T-A2T after antiglaucomatous medications applications; PDHC: highest concavity peak distance; DAHC: highest concavity deformation amplitude; SP-A1: stiffness parameter A1. Multiple liner regression analysis of different independent variable with .
