Hi all,
It's my first post. Basically, starting last Friday, I've twice had the following: Brief (30-45 seconds) greying/fading out of colors in my direct line of sight. I noticed it as I was reading a monitor. I could tell that the words above and below my direct line of sight were normal, and would fade as I focused on them. It appeared to be both eyes, but I can't guarantee that. I did close each today, when it happened, and believe it was that way for both. The words were not blurry at all. I have no other visual issues (no pain, no blurry spots, no vision loss, etc). It happened on black font today and a blue font and black font on Friday. Can optic neuritis be this brief? Unfortunately, the descriptions online aren't very helpful in that regard. They seem to say that just a greying a vision is not optic neuritis, and that it has to last for at least a couple of hours, usually lasting much longer.
I've been tested in the past for MS (have twitches (benign apparently), shakiness, tingling/numbness in feet, and some other symptoms), with my last MRI (on a 7tev machine I believe??) 3 years ago completely clean. I currently have new symptoms, which while scare me very much (tingling in hands, some perceived weakness in hand/forearm/twitching in index finger), I realize are most likely something like an ulnar nerve issue rather than MS/ALS. But add them to the vision issues and I'm more worried.
Further, it's possible I've had these vision issues before. I clearly remember staring at my monitor in the past and wondering why some text was greyer than others. For some, it actually was, and I had to the change font, but I seem to recall that that approach didn't work all the time. But because of my other fears, I'm more sensitive to this now, so I noticed it right away this time.
Thanks!!
