Temp loss of vision in right side of visual field, both eyes, five times in 2 years
 

Loss of vision in right side of visual field, both eyes, five times, twice with speaking disorders.
First time 18 months ago. Visual problem resolved in 10 minutes after aspirin, followed by verbal deficits for half an hour. CAT scan of brain two days later showed no problems
Then on 16 of June this year, same: visual disturbance, right side of both eyes, resolved after aspirin in 10 minutes. Drove self to hospital in 20 minutes. At intake I could not speak clearly. Could not pronounce name of common objects ( a pen being held in front of me). CAT scan OK, and by the time I was ready for MRI, all issues resolved.
Two smaller events a week later; visual field right side; like static on a TV, also short lived.
Tonight, Aug 16, same; felt very tired, drove home OK from work, started reading, noted right side of vision broken up, again like TV static. Also noted that for part of the time, after it began to resolve, I could not focus on center of text in a book; could see OK the left side of the line of text, not the right or center. Chewed on lots of aspirin; OK after half an hour.
QUESTON: WHY THE SAME SYMPTOMS each time? In other words, why the same part of the brain being effected????
This has been diagnosed as a TIA. It’s been suggested it’s all due to a fibroelastoma seen on an aortic valve by a TEE. I bought this diagnosis and am looking into having the damn thing removed, but now I don’t get why the clots formed by it would travel to the same part of the brain each time.
These recurring symptoms are telling us something. What?

Hello byterbit: I'm sorry I don't have the answers you seek. However I noticed this is your first post here on NeuroTalk. So I just wanted to say welcome. :welcome_sign: I hope you find the time you spend here to be of benefit. :Grin-Nod:

Hi byterbit

Welcome to NeuroTalk :).

I think that what you have described is technically called hemianopsia.

The most common causes of it are a stroke, a tumour or traumatic brain injury.

The information in these links might help you to discuss this with your health care team.
