I have a condition that the Mayo Clinic has been unable to diagnose effectively. There is a discolored spot on the macula in each eye. I have been told it is not macular degeneration and that it may be genetic. I also have significant photophobia, and am unable to use computers without software to invert colors. I can t read with bright backgrounds and experience physical eye pain when I make the attempt. Any suggestions or possibilities? In my own research, I came across Stargardt, but it isn t a perfect match, either.
