(A) Retinal vascular geometric variables assessed quantitatively by the Singapore I Vessel Assessment software. Arterioles are in red and venules are in blue. (B) At each bifurcation, the width of the trunk vessel (d0) and its two branching vessels (d1 and d2, d1 > d2) are measured, as well as the branching angle (θ1 and θ2, θ1 < θ2)
