Morphological changes of retina in FFA. (a)–(e) were FFA examination images of diabetic rats on the 8^th day, at the 4^th week, 6^th week, 8^th week, and 10^th week after induction in the diabetes group, respectively, while (f)–(j) represented FFA images in the normal group at corresponding time points. Yellow arrow indicated vascular tortuosity and dilation, blue arrow indicated rough and leakage of vascular, and red arrow indicated typical leaky vessels with vascular tortuosity and dilation. Scale bar: 200 μm.
