The causes of poor blood flow to the eye include injuries, diseases such as macular degeneration, Glaucoma, retinal vein occlusion, corneal hypoxia and injuries to the eye or eyelid.
Other health conditions that causes poor blood flow to the eye are heart disease, irregular heartbeat, alcohol abuse, cocaine use, family history of a stroke, high cholesterol, increasing age and smoking.
Smoking can cause vasoconstriction, which reduces blood flow to the eyes.
Poor blood flow to the eye can lead to an eye stroke.
An eye stroke can lead to a brain stroke especially if not treated properly and promptly.
Eye strokes are a type of stroke that occurs when a blood clot blocks an artery in your eye and causes vision loss and is the same type of clot that can also travel to your brain and cause a normal stroke.
People that have had an eye stroke are also at higher risk of having a brain stroke within the next couple of months and the risk of a brain stroke from an eye stroke is higher in the first couple of weeks after the eye stroke.
Retinal occlusion also known as retinal artery occlusion is a stroke that affects the eye and is also known as an eye stroke.
Symptoms of retinal occlusion or an eye stroke are severe blurring of vision and sudden vision loss in one eye.
Risk factors for retinal occlusion are male gender, cardiovascular disease, smoking and aging and advanced age.
If you're having an eye stroke or are experiencing retinal occlusion you should go to the ER immediately as it's a medical emergency.
The most common cause of retinal artery occlusion are blood clots or a cholesterol deposit which blocks the blood vessel in the retina.
The blockage that causes retinal artery occlusion can occur in your central retinal artery or even in the small arteries of your retina.
Risk factors for retinal artery occlusion are diabetes, high blood pressure, heart disease, heart valve problems, high cholesterol, carotid artery disease and blood clotting disorders.
You can sometimes regain at least some of your vision after retinal artery occlusion although the vision loss is often permanent.
In branch retinal artery occlusion visual field loss is often permanent although your central visual acuity may recover to 20.40 or better.
In central retinal occlusion vision loss is often severe although some people are able to regain vision to as much as 20/50 or sometimes better.
In central retinal artery occlusion vision loss is often severe and can also be permanent, although some people with a cilioretinal artery may recover to have 20/50 vision or sometimes better.
In branch retinal artery occlusion visual field loss is often permanent although central visual acuity may recover to 20/40 or even better.
The first symptom of a central retinal artery occlusion is sudden, painless vision loss in one eye which can occur over seconds.
Central retinal artery occlusion occurs when your central artery that supplies blood to your retina becomes blocked and can lead to severe vision loss and even blindness in one eye.
Other symptoms of central retinal artery occlusion include.
Floaters.
Sensitivity to light.
Seeing a dark curtain or shadow over part of your vision.
Vision may be completely lost or blurred.
And sudden painless vision loss in one eye.
Retinal artery occlusion is a condition in which an artery in your retina which is the light sensitive tissue at the back of your eye becomes blocked.
The blockage then prevents the blood flow to the retina and leads to vision loss.
Common causes or retinal artery occlusion are blood clots, hardening of the arteries also known as Atherosclerosis, and inflammation and trauma.
The types of retinal artery occlusion include central retinal artery occlusion which is the blockage of the main artery which supplies the retina.
And branch retinal artery occlusion which is blockage of a smaller branch artery in the retina.
The symptoms of retinal artery occlusion include.
Floaters.
Sensitivity to light.
Seeing a dark curtain or shadow over part of your vision.
Vision may be completely lost or blurred.
And sudden painless vision loss in one eye.
