The prognosis for retinal artery occlusion is often very good but also depends on how quick the treatment is received and the type of retinal artery occlusion.
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.
