Figure 8. Retinal capillary permeability assessed by the Evans blue method in control and diabetic spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) rats. The permeability was expressed in µl of plasma × g retinal wet wt⁻¹ × h⁻¹ wt. The results are expressed as the mean±SD. The following abbreviations are in effect: control WKY (CT-WKY), diabetic WKY (DM-WKY), control SHR (CT-SHR), and diabetic SHR (DM-SHR).
