Macular Perfusional Findings in Venous Obstructive Disease and Its Treatment: An OCT-A Evaluation

The human retina is supplied by an extensive network of capillaries, where healthy blood flow to various parts of the retina, particularly the macula, is vital for visual functions. Any obstruction in blood flow, known as retinal vein occlusion (RVO), can reduce venous blood return. RVO can occur either at a central location (called central retinal vein occlusion [CRVO]) or a peripheral location (branch vein occlusion [BRVO]). Various …
