摘要

Glaucomatous vision loss can occur at both normal and elevated levels of intraocular pressure (IOP) and the optic nerve head (ONH) is the principle site of damage. The mechanical environment of the ONH is believed to be critical for retinal ganglion cell pathophysiology [1]. Previous computational models have shown that scleral mechanical properties play an important role in affecting the mechanical environment of the ONH [2]. It is thus important to characterize the mechanical behavior of sclera under physiological loadings.
