Figure 7.

Differences in the material parameters between load-displacement cycles of all investigated scleras (normal, control, and treated) tested under Load Protocol A. (A) The elastic modulus of collagen fibrils increased from cycle 1 to 2. This increase was higher for higher elastic moduli at cycle 1. No further changes were seen between cycle 2 and cycle 3. (B) The crimp angle of collagen fibrils increased from cycle 1 to 2. This increase was lower for higher values at cycle 1. The crimp angle further increased from cycle 2 to 3, suggesting continued softening of the tissue as observed in Figure 4.
