Figure 4

The number and area of RGCs and the morphological changes in two groups of retinal tissue HE staining, respectively (magnification, ×400). Retinal tissue looseness and edema and loosely arranged cells were observed in the diabetic group but not in the normal group. (a)–(e) were the HE staining of the diabetes group.(f)–(j) represented HE staining in the normal group at corresponding time points. (k, l) represented the ratio of RGCs and RGCs area between the two groups at each time, respectively (, #). Blue arrows indicated new vessel buds, and yellow arrows indicated abnormally dilated microvessels. Scale bar: 25 μm. Abbreviations: d: day; w: week; RGCs: retinal ganglion cells.
