Superior/inferior temporal branch of the central retinal artery—adaptive optics ophthalmoscopy image. (a) Healthy volunteer. (b) Diabetic patient without retinopathy. (c) Diabetic patient with nonproliferative retinopathy. (d) Diabetic patient with proliferative retinopathy. Employing AOdetect software, the mean wall to lumen ratio was calculated from the three selected regions of interest, for each time landmark (100 μm width and height each).
