The Mann–Whitney test was used due to skewness of the data; detail information is given in the supplementary. CRAE: central retinal artery equivalent; CRVE: central retinal vein equivalent; AVR: arterial-venous ratio; Aasym: asymmetry index of arterioles; Vasym: asymmetry index of venules; Vangle: bifurcation angles of venule; Aangle: bifurcation angles of arterioles; BCV: bifurcation coefficient of venule; BCA: bifurcation coefficient of arterioles; Nicking: the narrowing of the venule at the crossing point of arteriole. Aocclusion: arterial occlusion.
