@riy No, at least not so far. Whatever is going on is specific enough that not even things like VEP testing in the past has provided any clues towards a possible treatment path.

There is one thing I did not mention in my initial report above however.

When looking at computer monitors, text appears as readable as it did many years ago, but a lot duller. However, some pictures, especially of human faces, are a lot different. Some pictures, which at one time had a lot of very fine detail visible to me, are increasingly appearing as washed out. This is identical in both of my eyes, pointing once again to some brain processing or optic nerve issue and not the eyes themselves.

Based on the affected pictures, this appears to be some form of contrast sensitivity problem and the problem does NOT change gradually over time but remains stable at its current level until another attack at which point there is a sudden change in how washed out the affected pictures appear to be.

Note that there are absolutely no washed out artifacts when I look at people in real life.

I am not a medical expert, but I am a computer professional, so I am aware that the resolution of the pictures on a computer monitor are far less than the resolution in real life so there is far less redundant information for the brain to work on per unit area when looking at something on a computer monitor. This might matter if the brain is not receiving all the visual signals it should be due to some damage somewhere.

I wonder if this might give someone some clues about why the symptoms are even more severe with computer monitors ?

PS: In my message above, I meant "medicine diary", not "medicine dairy". 🙂
