Example tissue samples with their corresponding markings for morphometry. From each whole fresh eye (top row center) (Adapted from Sigal et al.³⁸), four regions were analyzed, including cornea (a), equatorial sclera as a rectangular piece (b), posterior pole containing the optic nerve head - PPONH (c), and posterior sclera strips (d). Areas were computed from the outline of the tissues (a–c). Measurements were taken separately of the ONH as a whole and of the scleral canal (c). In equatorial and posterior sclera (b and d), lengths and thickness were measured at two locations averaged.
