Figure 2. Comparison of the neuroprotective effect of resveratrol according to the different concentrations. In optic nerve transected (ONT) eyes, resveratrol in the concentration of 3.1 uM or more showed statistically significant neuroprotective effect for the retinal ganglion cells (RGCs) compared to the control group (n≥4 for each group, *p<0.01, one-way analysis of variance [ANOVA], post hoc Tukey test, error bars represent standard deviation).
