I was diagnosed with PMR this last September. And it seems like my vision has gotten noticeably worse also. I've been told the same thing as you regarding my cataracts. Not ready yet. But I'm wondering if the prednisone is affecting my vision now. I mentioned this to my rheumatologist at my visit two weeks ago. He also was unimpressed, and seemed to indicate that the vision loss is a sudden thing that occurs and made a gesture of slapping his hand to his eye. I assume he was saying it's a dramatic occurence rather than a subtle one. However he told me to go and get an eye exam asap and then get one once a year. My last eye exam was this March, but he still wanted me to go now.
