Figure 2. Lipid peroxidation products were significantly elevated in organ culture medium collected from the lower level of the vials where the donor corneas had been stored for 7 days when compared to medium from the upper level and from fresh control medium. Statistical analysis by one-way ANOVA showed significant differences between the groups (p=0.000) and was followed by the Bonferroni multiple comparison test (p<0.05 between the groups linked by square brackets).
