value: regression coefficient and values of the independent variables in the generalized estimating equations. The influence factors as age, sex, axial length, central corneal thickness, and spherical equivalent have been adjusted. Δ, the change of the variables between 0, 15, 30, and 60 minutes postexercise and preexercise (baseline) values. IOP: intraocular pressure, SC: Schlemm’s canal, CI: confidence interval.
