I have still yet to be diagnosed, have been to
Houston, Miami, Minnesota, and live in Louisiana where I have also been seen by doctors. On my lasts venture to Minnesota, I was told I have a Macula Dysfunction, not degeneration.
I am 63, have had 20 20 vision my entire life, and within the last year started losing my vision and now am legally blind. I have many symptoms, flashing lights is just one, but it is the center vision that is gone. My eyes and retina are completely healthy.
