Our results showed that the meridian tensile strains in the posterior porcine sclera were significantly larger than the circumferential tensile strains during biaxial loading (P＜0.05), suggesting an anisotropic response of the tensile strains. The compressive strains were significantly higher in magnitude than the corresponding tensile strains, but were not different between the circumferential and meridian directions. Model fitting results showed no significant difference in the material constants A_1 and A_2 (P＞0.05), although limited by a small sample size (n=5).
