Microglial infiltration during diabetic retinopathy in the Nile rat. a Abnormally high density of microglial cells in a retina with proliferative diabetic retinopathy. b An age-matched control of panel (a). c An activated microglial cell at high magnification from the same retina as in panel (a). d A resting microglial cell at high magnification from the same retina as in panel (b). e Several microglial cells surround a highly tortuous arteriolar structure in a diabetic retina. f A few microglial cells surround a dilated venule in a diabetic retina. Scale bars of (a, b, e, f) = 50 μm. Scale bar of (c) and (d) = 10 μm
