It was my Opthamologist who made me get off of Prednisone. It was literally blinding me. She saved my sight by doing all the tests (field of vision testing) that proved her right. Prednisone can cause glaucoma, which is very insidious as there often are no symptoms before your eyes get harmed. What she and no one else in that State (Alaska) had for me were the new laser surgeries available to treat the kind of glaucoma I got from the Prednisone. I had to literally move down to WA State (where I had relatives) and it was only by accident I found out about the laser surgeries. The kind of glaucoma that high doses of Prednisone gave me is called Open Angle Glaucoma. The laser surgeries can also be repeated. Which was very good news, because I've now had 3 of them. 2 on the eye most affected, and 1 on the other. I now have 2-4 check ups with a glaucoma opthalmologist, yearly. The PMR went into remission, and my raynaulds disappeared too, when I left the cold behind. Though one apt I rented turned out to be on a cement floor so I had to get rugs to cover the linoleum, especially in the bathroom where we all tend to have bare feet at bathtime. There are medication drops for glaucoma too, but I couldn't use those, which is why I learned of the laser surgeries early. They're seriously medically approved procedures, only trained opthamologists do. Good luck.
