Causes of retinal vein occlusion

Retinal vein occlusion is a very common disease in our ophthalmology, second only to diabetic retinopathy. Well, its causes are also relatively complex. First, for example, this patient has hypertension, diabetes, hyperlipidemia, and other vascular diseases. Then, it will damage the retinal vein in our fundus. After one of its endothelium, endothelium is damaged, in addition to changes in hemorheology, and then changes in hemodynamics, etc. This will cause the blood flow to be relatively slow, removing blood stasis in our blood vessels, and eventually causing our veins to expand and then rupture. In addition, there are also some anatomical factors. For example, in this patient, at the cribriform plate, the retinal veins and retinal arteries all pass through the cribriform plate. If the cribriform plate is relatively narrow and crowded, then at this time, the arteries and veins will press each other at this place. Especially in patients with arteriosclerosis, the vein will be ruptured after being compressed. Expert model: retinal vein occlusion causes more complex, if the patient has vascular disease, then it will damage a endothelium inside the retinal vein, causing blood stasis in the blood vessels, and finally causing vein expansion rupture. In addition, there are anatomical factors, if the patient's cribriform plate is relatively narrow, then the artery and vein in this place will cause vein rupture.
