Figure 5. VEGFR-2 staining intensity of the RGC layer. There are two important points in this graph. The first one is the high VEGF response to the ischemia and reperfusion and its significant suppression by bevacizumab (** p<0.01 and *** p<0.001). Data expressed as median ± standard error of the mean (SEM; n=6). BEV = bevacizumab; IR = ischemia-reperfusion.
