When the blood supply to the brain is cut off due to plaque build up or blood clots?
There are two types of stroke: An ischemic stroke occurs when blood clots or other particles block the blood vessels to the brain. Fatty deposits called plaque can also cause blockages by building up in the blood vessels. A hemorrhagic stroke occurs when a blood vessel bursts in the brain.
What are the abnormal findings in the retinal vessels?
Observable changes in retinal vascular architecture, such as increased retinal vein caliber (decreased artery-to-vein ratio), retinal vascular tortuosity, increased prominence of the retinal arterial reflex, venous nicking, “copper” or “silver wire” appearance as well as the discovery of cholesterol, calcium or …
What are the symptoms of blood vessel blockage?
The symptoms of an artery blockage include chest pain and tightness, and shortness of breath. Imagine driving through a tunnel. On Monday, you encounter a pile of rubble. There is a narrow gap, big enough to drive through.
Which problem does blockage of blood supply to the brain cause?
Carotid artery disease occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries). The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced.
What does a retinal scan show?
