I am a 52 yo male with no health problems (i'm aware of) other then this..I am a smoker, a vegetarian and excercise pretty regularly..mainly by running.
Feb 2 yrs ago i was driving around NZ on holiday when i noticed i could not see the right half of the car number plate in front of me..this went on for about 30 mins then passed.
A month later i was at work when i realised i could not see what i was trying to read at work..again around 30 mins duration.
A week later i came home after a run and realised i could not see the right 1/2 of what i was trying to read on my pc..again it lasted about 30 mins.
Next day it happened again.
At this point i was freaking out so managed to arrange an appointment at my GPs (even though i couldn't read the phone book lol)
She said she'd covered this in her training and happily informed my about tumours etc..Anyway i had blood tests but nothing turned up except a possible minor infection which showed from a slight increase in my white cell count..
I had no more symptoms until almost exactly 2 yrs later..last month.
I was coming home in broad daylight from a course at work and feeling very relaxed when i realised i couldn't see what i was focussing on..people, cars signs..it was as though they didn't exist but everything around them did...again 30 mins or so duration.
Then 2 weeks later after another run..it happened again.
Only this time on the left side?
I'll attempt to describe what it's like...it's as though there's a curved downwards silver rippling ribbon in the same place in both of my eyes with a blank area below it where i can't see. Not a hole but an absence...?
I have no pain nor any other obvious symptoms whilst this occurs...
My fasting Cholesterol was slightly high but i take Vit C 1G daily to sort that.
Family history from my sister re her 'hemianoepia' experience.
"CT scan "normal for my age", Carotid Doppler's showed 50% blockage - again apparently normal for my age. MRI scan also normal. Serum cholesterol through the roof and am now on anticholesterol meds and levels well down. I know you have views on this med but seems to have done its job and would rather have low readings than high, with their association with strokes.
Have had a couple of similar episodes since the. Happened when I was tired and dehydrated, I think. Also occurred on either side and passed off in ten minutes or so."
