Sudden incremental reductions in brightness levels while everything else remains normal.

The comment about dilated pupils is confusing - sorry. What I meant to say is that at my original brightness levels, dilated pupils were painful outside, just like they are for everyone else. However, at the current reduced brightness levels, I no longer feel the same pain when outside with dilated pupils.BTW, is this the correct section to be discussing this ? Would it be better in the Sensory section ? Also, does anyone know of any more specialist reputable forums where I might get some ideas about suggestions to put to the doctors ?Thanks.0

Hi @YorkshireMan and welcome to the community.
Please don't worry about which category your post is in, sometimes conditions span multiple categories.
I'm afraid I've not heard of anything like you've described, but I really hope something shows up on your next MRI. I'm hoping one of our regulars may be able to offer some advice soon.0 -
Cataract?0

No, it's not a cataract, but thanks for the suggestion. Cataracts develop over time, not suddenly in both eyes overnight. They have also been eliminated as a possibility by the consultants.

Hi @YorkshireMan. I'm glad they've been able to rule out cataracts. Are you going for any more tests?

I can assume that the problem is in the visual center of the brain. Try CT perfusion imaging, PET CT.

Rachel: I have had another standard MRI (it has been a number of years since the last one) but I do not know the results yet. Not optimistic it will turn up anything however. :-(
egister: those are some interesting suggestions thanks. I will look at them and discuss if they are applicable with a consultant I am seeing next week in a final followup about another issue. (Nothing related to this - it was a tiny retinal tear in the outermost part of my left eye that appears to have developed sometime over the last year without any of the usual symptoms and without affecting my vision in any way. It was discovered during other investigations - I didn't even know I had it. BTW, those lasers HURT but it's better than the alternative. :-) )
One of the most annoying things about this is that it is very clearly something very unusual in that it suddenly reduces brightness levels slightly but permanently without affecting anything else in the vision system, so it is proving very hard to track down as it doesn't match anything the consultants are aware of.
