Well, I've just tried looking hard L/R and I don't get a 'spot', though my nose does seem to obstruct my view a bit.
Something odd I've noticed when driving and fatigued, I tend to tip my head to the left a little bit. If I try to keep my head straight and look forward, I see double. If I tip my head to the left just a bit, and keep my eyes forward (basically looking a little to the right), I see just fine with no double vision.
I also would get (in times of extreme fatigue, from lack of sleep/rest) 'halos' or "Cs" of distorted vision in both eyes. Sort of like the precursors some people get with migraines, but I wouldn't get a headache, just that funky vision. If I laid down and closed my eyes for 10-20min, it would go away.
ALSO, I noticed with prednisone use, my vision has deteriorated to where I need (NEED) reading glasses to read the print in books and magazines. When I brought this up to my GI Dr, she said it was because I was approaching 40, not the steroid use. Well, when we tapered off the 'roids and I'd been off them for a bit, I happened to pick up a magazine and start reading an article, before I realized I was doing so without my reading glasses!
So, I do feel our condition and medications can play a big part in our vision. Bring it up with your Eye Dr, though I wonder if you and your son share this symptom if it isn't just a genetic trait?
I have an Eye Dr. appt next month and I'll share what he says if it is pertinent. Let us know what your Eye Dr says, too.
I have the ability of single-minded determination and accurate project focu....Hey, look, a cat!
Crohn's and UC are pretty darn crappy, but if you can't laugh at yourself, you'll cry.
I'd much rather laugh.
2001 Dx'd with UC. No remission. 5/2008 surgery, removal of 6" of left side colon. Dx changed to Crohn's. Remission for 8-9wks after surgery, symptoms returning after resuming 6MP.
