Does blockage in arteries of retina cause vision loss?

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 more

Can staring at the sun as a kid (around 8 years ago, I'm 18 now), cause blindness/loss of vision later in life? (I've recently had a digital retinal scan done around 6 months ago and my optometrist said my eyes were perfectly healthy)

Effect is immediate: Your focusing eye elements will concentrate the sunlight and cause a burn if you hold steadily staring at the sun. This is difficult and painful to do and your reflexes will mostly prevent this. If you did not become aware of immediate damage, you will not get damage at a later date. ...Read more

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?

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 more

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?

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 more
