I first wanted to say that I am sorry to hear about your eye but at the same I have to say NEVER and I mean NEVER say that about your dreams, you can still do this! I may not know anybody in Concept Artist industry with such impairment but I know that Beethoven for example was deaf and yet still became the best at his time for playing the piano, Dante during the Renaissance wrote a lot of his best work still remembered to this day although being blind. Whenever there is a will there is a way! I was also looking through future treatments for Macular Degeneration and found a lot of promising treatments from bionic eyes to stem cell research. What ever happens you still are in control of your life and not some obstacle life has put in your way. I know it may be hard but you will pull through, I am counting on it!
