Retinal branch vein occlusion

Branch retinal vein occlusion is a disease of fundus, which can cause vitreous hemorrhage and even retinal detachment in severe cases. Therefore, branch retinal vein occlusion is also a serious disease. Branch retinal vein occlusion is a kind of retinal vein occlusion. Because most of the occlusion site is at the intersection of artery and vein, it is presumed that the hardened arterioles compress the retinal vein in the common sheath, causing the blood flow in the vein to form turbulence and damage the vascular endothelial cells, thus causing thrombosis and causing vascular occlusion.
