Vascular permeability in the retinas from normal Wistar rats (Control), GK rats treated with vehicle (Diabetic), GK rats treated with CD (CD), and GK rats treated with RRP (RRP) was measured with Evans blue as a tracer. Evans blue was normalized by total protein concentration in the tissue. Permeability is expressed as ng of dye per mg of protein in the tissue. All data were expressed as mean ± SD ( ). versus Control group; versus Diabetic group; versus Diabetic group.
