Figure 1. Analysis of neuroprotective effect of resveratrol at 1 week after optic nerve transection. A: The numbers of retinal ganglion cells (RGCs) of eyes treated with intravitreal injection of resveratrol (31.3 uM) in the transected rats (C) were significantly larger than those with injection of PBS in the transected rats (D), but smaller than those with injection of PBS in the nontransected rats (B; n=5 for each group, *p<0.01, one-way analysis of variance [ANOVA], post hoc Tukey test, error bars represent standard deviation).
