I’ve had some trouble with my vision also, just never tied it in with my PMR! I don’t have any other symptoms of GCA, I do know to look for those. One day it felt like I had Vaseline over my eyes! But using dry eye drops and putting a warm compress helped get rid of that. It’s frustrating because I just had a diabetic eye exam and an exam for glasses and now my vision is off and on blurry! I have an appointment with my pcp today and I’m going to ask her about it.
