Figure 4. Representative fundus images of the same retina 14 days after injection of AAV-CMV-GFP. A is an image taken under bright light illumination. B represents the image with GFP signal only. Features in the retina are labeled as follows: BV = blood vessels, ONH = optic nerve head, and RGCs = retinal ganglion cells. The images have been enhanced using the sharpen tool on Adobe Photoshop. Scale bar = 200 μm.
