@hopeinal I haven't experienced this with my occurrences of PMR but I think it could be Giant Cell Arteritis (GCA) which can cause vision loss if not treated early. There is another discussion you might want to read here:

Have you told the doctor the eye medications are not working? Do you have a rheumatologist that you can call?
