Figure 1. Schematic of sclera locations. This figure shows the schematic of an inflation tested left eye, where Rk indicates the labeling of regions. The positions of points along the scleral edge were calculated for the initial image (reference configuration) and for the subsequent images (deformed configurations) in the (e1, e2) Cartesian coordinate system. The axis of revolution was defined as the axis passing through the center of the optic nerve head (ONH) parallel to the axis of the ONH.
