Why did I have loss of vision and grey field in one eye briefly? Under stress then.

Many reasons: Its difficult to answer these kind of questions, not knowing some information. However, it could be migrains, tia, amaurosis fugax, visual changes induced by exercise, drop in blood pressure, etc. Stress in itself wouldn't cause a brief loss of vision, although it has been associated with central serous chorioretinopathy, which can cause a prolonged distortion of vision. ...Read more

If you get paint thinner in your eyes, will it cause instant, permanent loss of vision?

No: Paint thinner is caustic and can cause significant ocular damage if prolonged contact occurs. If you flush it out quickly, severe injury can be avoided. Vision after a corneal burn from paint thinner will be poor immediately after the injury but should improve as the eyes heal. The final vision varies depending on the extent of the injury. ...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)

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

Repeated loss of vision in left eye, no pain. Had thorough eye evaluation, no problems. Have an appointment with a neurologist, but it's in march?

Need to be seen soon: Very worrisome problem that needs immediate attention. While a thorough eye evaluation us reassuring, things outside of the eye can cause vision loss. Your profile mentions amaurosis fugax so you already have problems with blood flow. You could be having mini strokes to the part of the brain that controls vision. Also some conditions like vasculitis can affect vision. Get in somewhere right away. ...Read more

Dr said swollen left eye optical nerve caused loss of vision in my lower left eye. After 5 months the swelling is gone and he says the damage is perma?

Ischemic optic nerve: You most likely had ischemic optic neuropathy, a condition in which there is a disturbance in blood flow to the optic nerve which causes the optic disk to become swollen and is associated with loss of peripheral vision. 40% of patients get some improvement in vision as the optic nerve swelling improves/resolves. Common risk factors are hypertension, diabetes and high cholesterol/lipids. ...Read more

What's it called when someone has loss of vision on the left side of their peripheral vision in their left eye preceded by eye pain/pressure feeling?

Do you mean scotoma?: Well, there are a few medical terms that could describe your visual loss phenomenon but in point of fact, your pinpoint exactness of what is being lost from where is unlikely to be precisely what's happening anatomically or physiologically...though that's what's apparent to you. What is known to you are the headache or likely migraine symptoms. Have you seen a good headache specialist. May help. ...Read more

What's the reasoning behind temporary vision loss in one eye?

Possible causes: A blockage of blood flow to the retina can lead to a black out of vision in one eye. This can be caused by plaque breaking off of an artery and lodging in the eye. Since the blood flow to the retina is limited, the vision will abruptly and painlessly be lost. When the plaque dissolves the vision will return. If the blood flow is obstructed too long (90 minutes or so) the vision might not return. ...Read more
