Loss of peripheral vision in my left eye

[janeth16]

Hi,
Today, for the second time in about 5 weeks, I experienced a sudden loss of peripherial vision in my left eye. I was able to see well with my right eye, but with my left I had blind and blurry spots.  The problems were more prominent as I tried to see to my left. I could not se my left hand if I put it toward the left of my face.  When trying to read my sight would miss entire words.

I had no pain at the moment, but later when my vision returned to normal, I had a terrible heachache.

Any thoughts? Do you think is an isolated event?

Doctornee has outlined possible etiologies.

My advice is that you have a "general quarters" emergency warranting an immediate trip to an ER for an evaluation by an opthamalogical neurologist.

You have what are called "focal findings". That is they are localized in one specific area.

Generally this is because of intermittant pressure on an optic pathway, which may be caused by a growth, inflammation  (possibly due to infection) or ??????????

There are more nasty possibilities, as doctornee suggested, namely carotid artery aneurysm.

Fortunately, modern medicine has both the MRI and the MRA available to perform differential diagnosis.

Put an ER visit at the top of your list of "things to do".

Hi
Welcome to the MedHelp forum!
The simplest reason for unilateral (in one eye) hemianopsia or hemianopia is migraine. This causes temporary loss of vision is one half of an eye. Other causes are injury to brain, brain tumor, infection of brain, infection of optic nerve, injury to optic nerve, optic nerve tumor, stroke, carotid artery aneurysm and injury to the occipital lobe of the brain. A neuro-ophthalmic consultation will throw more light on the exact cause. Take care!
