Since many of the posts on this subject are a bit old, I thought that a new string would be helpful.
Some years ago I started having episodes of blind spots in my field of view and flashing patterns. They went away after about 20 min. After many tests, it was concluded that I had “migrains with out the head ache”. I went off of coffee and other caffein and they diminished in frequency until I hardly had them at all. My wife had they same experience and she switched to decaf. and they diminished for her as well.
Now in the last week I have had two episodes after a long time with out any. It makes me wonder if my MDS has triggered them or if something else that I am ingesting causing it. I am now juicing every day with a varity of vegitables and fruits. (pineapple evey day to see if it helps with my platelet count. and a lot of carrots and greens)
