Does Blockage In Arteries Of Retina Cause Vision Loss
See a retina special: Yes. Lack of blood flow due to a retinal artery occlusion can cause severe loss of vision from damage to the retina. A central retinal artery occlusion is worse than a branch retinal artery occlusion. There are no good treatments, but a systemic workup looking for an embolic source is required (carotid ultrasound, echocardiogram). A rarer cause is giant cell arteritis. ...Read moreSee 2 more doctor answers
Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more
I have loss of vision in one eye, several times a month. Is it caused by a temporary blockage like a blood clot?
Would a clot in your head manifest with transient area of vision loss with activity, but normal retina? Only 21 but worried because i've hardly done any exercise for a year due to severe pots?
Blood clot in posterior to the retina due to blunt injury to the eye with loss of vision. Pls tell me if the vision comes back or not?
Depends on damage. : Traumatic retinal hemorrhages can range from superficial to catastrophic. If there is too much damage to the retina or there is blood underneath the retina, the damage may be permanent. In that case, the vision may not come back. See your retinal specialist for more specific information. ...Read moreSee 1 more doctor answer
Serious!: Sudden vision loss can have many causes, including but not limited to retinal detachment. Until proven otherwise, sudden vision loss is very serious, and should be evaluated urgently. In some cases, usually in older individuals, there is also the risk of also loosing vision in the fellow eye, making this symptom all the more urgent with increasing age. ...Read moreSee 1 more doctor answer
I was diagnosed with retinal macroaneurysm resulting in vision loss (2 mo. Ago) a lot of the floaters have gone away. How long until all are gone?
Floaters gone by?: First, it is unlikely that the retinal macroaneurysm is directly related to the floaters unless there was bleeding. Assuming this is the case, the floaters will go away in most cases within months. Some persist and become a nuisance. It is a good idea to have a retinal specialist take a look at them. Sometimes a vitrectomy is appropriate. Good luck. ...Read moreSee 2 more doctor answers
I have been occasionally waking up with dim vision in left eye. I have a 60% blockage of my carotid artery on the left. Could this be the cause?
Maybe: Amaurosis fugax is what you are referring to. The plaque in the carotid artery can shed particulate matter upstream, and when this enters the artery going to the same side eye, typical symptom of "shade coming over the eye" is experienced. Visiting an eye doctor may help make this diagnosis. ...Read moreSee 2 more doctor answers
Maybe: There are different types of drusen. Soft drusen are thought to be the biggest risk for vision loss. They can lead to large areas of retinal loss with "dry" macular degeneration, or for reasons that have yet to be fully understood, lead to a break in the foundation layer of the retina and allow blood vessels to grow and destroy the retina-termed "wet" macualr degeneration. ...Read moreSee 2 more doctor answers
A long list: Any part of the eye and brain can be affected in a way to cause vision loss. The cornea and lens can gradually lose transparency sometimes with inherited conditions. The retina can lose function from disease like diabetes or inherited problems. The optic nerve can degenerate and the brain can have strokes or tumors affecting vision. ...Read more
