Oh my, I have prayed that the doctors would be able to discover the problem and find ways to correct it. I'm thinking of you both!
Did the doctor actually say that they were exclusively looking into the possibility of a rare condition?
A few years ago, my dad was reading the newspaper one Sunday morning when, all of a sudden, he couldn't see the upper left quadrant of the paper. That is, if he looked at a wall, the upper left section of his vision simply wasn't there. He called out to my mom, a registered nurse to come in. When she came in, he could only see her from the waist down. (?!!!) She drove him to the hosptial where he underwent lots of tests which came out normal. At the end of it all, his vision came back by itself and they concluded that he had experienced an "atypical migraine". This type of migraine is one that is not normal for whatever reason - in this case he did not feel a headache. Migraines are known for messing up vision.
A year or two later, I started having blurry vision, but my head didn't hurt or anything. I too had to go to a doctor to undergo all kinds of tests including an MRI (I didn't fall asleep!!) to check for brain tumors. My MRI came back completely normal. Guess what the doctor told me? He said that he believes I had an atypical migraine! Funny that, across two years and two doctors, my dad and I both had the same condition. I guess it's hereditary.
At any rate, I'm hoping that your husband could be experiencing something as simple as that.
Sending good wishes your way!
