Figure 10. Distribution of retinal ganglion cells (RGCs) in control and experimental retinas. A, C, E: Retinal photomontages showing fluoro-gold traced RGCs and B, D, F: their corresponding isodensity maps. A, B: control mouse; C, D: experimental retina processed 90 days ALE; E, F: experimental retina processed 180 days ALE. Isodensity maps are filled contour plots generated by assigning to each one of the subdivisions of each individual frame a color code according to its RGC density value within a color-scale range that goes from 0 (purple) to 5,700 or higher (red) RGCs/mm² (B bottom). The numbers of RGCs in these representative retinas are shown at the bottom of A, C, E. Bar=1 mm.
