It appears that I have it and I am terrified. I just went to the doctor and he has more tests to run, but he said that I must immediately discontinue the medicine and that the disease may progress anyway. I was too scared to ask if I would eventually go blind. I guess I just need someone to give me some hope. I first noticed it getting harder to drive at night. It also seems as though colors aren't as easy for me to distinguish, and I am more sensitive to light. My central vision has never been that great and I have worn glasses for decades. I want to know what could be ahead for me, but at the same time -I don't.
