No GCA eye issues but plenty of other eye problems. Actemra was used to treat refractory PMR and possible subclinical GCA.

I have another autoimmune disorder called uveitis which can also cause vision loss. With over 30 flares of uveitis, I'm very familiar with taking 60-100 mg of Prednisone to control those flares.

My other eye problems are mostly Prednisone side effects.
