I had a very strange problem which started about six weeks ago.
I was looking at my computer screen one morning. Just in my right eye, I noticed a blind spot straight ahead, in the dead center of my field of vision.
The blind spot slowly became a silvery-yellow line, covering about 60% around the perimeter of a circle in the center of my field of vision. The circle started throbbing slightly with my pulse. After about 30-45 minutes, it went away.
When this happened for the first time, I had a slight sinus flare-up and a mild headache, so I chalked it up to that.
About two weeks later, it happened again. This time, I had no headache. It came out of the blue.
Both times were at about 8:30 in the morning. Ever since then, my eye muscles have been aching slightly, and have been rather sore.
I've seen eye specialists in the UK, and none of them can find anything wrong. My retinas and maculae are in perfect condition, and the pressure in my eyes (12R, 14L, if that means anything) is completely within the normal bounds.
I'm very concerned because there is no logical explanation for these symptoms. I've never had migraines and have no immediate health problems.
Any ideas what's wrong?
