I had blurred vision for ten years in both eyes, sometimes better, sometimes worse, throughout each day. I could no longer play the piano or organ regularly, never knowing when I could see the music or not. Reading was the same way, and also complicated by brain fog, of course! I had pretty much adjusted to the idea that blurred vision was permanent, a very not fun part of ME/CFS or FMS for whatever reason.
Then, in January 2010, I started a course of hCG for weight loss, not only for the weight loss but for the detoxifying effect it would have. I had studied it for five years, and decided -- correctly, according to my medical doctor -- that with the strict diet and loss of fat, it would detox my system thoroughly, perhaps ending 20 years of misery with systemic candidiasis. Well... that's just what happened. I lost 35 pounds, lost candidiasis -- and the blurred vision, entirely. The eye doctor was able to confirm it completely, as he had done my previous exam the year before.
My vision, I believed, had gotten worse. I could do nothing, no needlework, no reading, could not enjoy movies, no music, etc. I postponed making an eye appointment for about three months because I didn't want to hear how bad my eyes were. Surprise, surprise! My eyes were "bad" because all my corrective lenses were off 1 1/2 diopters, so of course everything was worse. The doctor stood there looking at one exam sheet to the other, just dumbfounded, but could not dispute the findings as he had done both exams. He said,"This never happens. Your eyes have IMPROVED." He asked me what had changed, what did I do differently. I told him I had both FMS and ME/CFS, and that possibly it had improved with the detox. He had no explanation for it.
I happily accepted his diagnosis of finally needing bifocals, and have just loved them! I CAN SEE again!! It was an emotional high by itself for months. He also ordered single-vision contact lenses for me (I love to go dancing! -- even though these days that means sitting and visiting at a dance) and single-vision glasses for me for computer work and music. Everything I had lost was given back to me that quickly.
A side note about using hCG: I was very, very weak from that regimen, and do not recommend it at all for someone with ME/CFS. It is an 80-year-old regimen, proven and extremely safe for someone in good health. For a sick person, it is not easy to do, and I would not ever dare do that again. Also, the regimen will "reset" the hypothalamus and reset body metabolism, something that did not happen for me. I was a happy but hungry size 8 for 14 months before I gave in and let some weight creep back on. I'm happy with my body as it is now, but do wonder about toxins being stored in fat and wish it were off for that reason. Waaaa, I'm a size 10, ha, ha, ha. So what!
I'm intrigued by the idea that the eyes are so affected by the lymph system. In my thinking, that lends credibility to the whole detoxification theory behind my eyesight improving.
As for the hypothalamus... I'm also intrigued to read on this site a few threads about the HPA axis and possible abnormalities in ME/CFS, which could explain the failure of the hCG regime to "reset" anything.
