Table 6.

Strain response of the PPS due to IOP increase from 10 to 30 mmHg, before and after treatment. The principal strains (E_max, E_min, γ_max ) and E_θθ were significantly greater after treatment with TrypLE than before (n = 8, p ≤ 0.02). Values are mean ± std, and p-values are from Wilcoxon signed rank test comparing the values before vs. after treatment within one treatment group (n = 8 per group).
