Hello everyone. I'm new to the group. I'm here because my father was diagnosed with GCA very recently. Unfortunately, he had very few, if any conclusive symptoms of the disease until he lost all vision in his left eye, and nearly all in his right eye on Christmas Eve. He was only started on steriods a week after vision loss, as the doctors were still grappling with a diagnosis. Everything that I've read indicates that vision loss due to GCA is irreversible. I'm looking for some hope that someone has had a different, more positive outcome. This has been difficult to say the least for our family, and we're devastated. Any help or insight would be greatly appreciated. I'm truly heartbroken for my father.
