Regional mean and standard deviation of complex modulus, tan(δ), and dynamic viscosity measured at pre-stresses equivalent to IOP loadings of 15, 25, and 45 mmHg. Error bar represents standard deviation. Complex modulus and dynamic viscosity increased significantly while tan(δ) decreased significantly with increasing pre-stress levels across all sclera regions (P<0.001, indicated by *). Tan(δ) was significantly higher in anterior sclera than equatorial and posterior sclera (P=0.003 and 0.018, indicated by † and ‡, respectively). There was no significant regional difference of the sclera in terms of complex modulus or dynamic viscosity (P=0.60).
