Figure 6. Overexpression of proNGF caused the breakdown of the blood-retina barrier. A, B: Representative image and morphometric analysis of fluorescence intensity in serial sections of rat eyes showed that retinas
injected with pGFP-proNGF123 had a twofold increase in fluorescence compared with controls injected with p-GFP. The asterisk
represents significant difference as compared with the control group at p<0.05. GCL, ganglion cell layer; IPL, inner plexiform
layer; INL, inner nuclear layer; ONL, outer nuclear layer.
