**Figure 3. **Analysis of neuroprotective effect of resveratrol at 2 week after injection. **A**: The numbers of retinal ganglion cells (RGCs) of eyes treated with resveratrol (31.3 uM) in the transected rats (**D**) were not significantly different from those with injection of PBS in the transected rats (**B**, **C**). However, the numbers of the RGCs of eyes with intravitreal reinjection of resveratrol (**E**) were significantly larger than those with PBS in transected rats (**B**, **C**; n≥5 for each group, *p<0.01, one-way analysis of variance [ANOVA], post hoc Tukey test, error bars represent standard deviation).
