Retinal Artery or Vein Occlusion belongs to the category of retinal vascular disorders. Normally occuring in older patients with signs of systemic vascular disease i.e. hypertension, diabetes, hyperlipidemia and heart disease, it happens when one or more of the blood vessels in the eye becomes blocked, causing water to build up and the retina not being able to function appropriately, resulting in visual loss.
