I’m working on a writing presentation and need support to help me understand better.Have you seen black dots or flashes of light? Do you know that sudden vision loss may be due to a condition that affects your central vision? Central retinal vein occlusion is a disease that may show no signs or symptoms in its early stage, but over time it can raise some worrisome questions. Patients with diabetes, hypertension, and other eye problems such as glaucoma may be the main risk factor for this not-so-well-known disease.
Treatment is based on the stage, severity, or diagnosis of the patient. Intravitreal injection is the main treatment for this type of disease, but we also have Focal lasers that will ensure the sealing of the leaking vein, and last but not least, we have Photocoagulation therapy. The retina of the eye has a main artery and a main vein. When the main retinal vein becomes blocked, it is called a central retinal vein occlusion (CRVO). The pathogenesis of RVO is believed to follow the principles of Virchow’s triad for orogenesis, involving vessel damage, stasis, and hypercoagulability. In non-ischemic RVO, blurred vision is mild and may be worse upon awakening and improves during the day. In ischemic CVVO, visual impairment is sudden and severe.
There is no convincing evidence that medical treatment favorably alters the natural course of central retinal vein occlusion itself. Pilot studies have suggested that oral platelet and erythrocyte aggregation inhibitor and hemodilution therapy to lower blood viscosity may be beneficial. Intravenous administration of streptokinase appeared to reduce morbidity, but has never gained popularity due to the risk of intravitreal hemorrhage
