**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).
