I can relate but no answers as well. I have had PMR and not GCA. My vision at times has been very blurry. Almost a gloss over my eyes. I can be reading and have the words completely gloss over. I have been off prednisone for 2.5 years. My thought it was a prednisone related issue. My eye exams have shown no issues. Thinking now it might be something else. High Cholesterol? High blood pressure? Or maybe one of the medications to treat either of the two. Age related? Mine comes and goes. IDK..
