Hydrogen sulfide donor and retinal damage in diabetic mice. Representative images from 5 to 7 mice/group showing (a) trypsin-digested retinal microvessels, stained with PAS showing acellular capillaries (thin arrow) and pericyte ghosts (thick arrowhead); (b) fluorescein angiography. The insert shows vascular leakage, and the histogram represents permeability intensity (c) OCT by the OCT module of Micron IV showing thickness of the total retinal layers and GCL + IPL at 200 to 400 µm away from the optic disc using the caliper tool in the InSight software; the histograms represent mean ± SD of the values from those mice at 300 µm. *P < 0.05 and #P < 0.05 compared to normal and diabetes, respectively.
