Hi Gron,.. and Welcome to KA!
Thank you for sharing this info with our group. I am so sorry to hear that you had to give up Enbrel for this reason, although I can't imagine they would keep you on it after such an adverse reaction; inflammation of the optic nerve is far too serious.
I'd heard from one Rheumatologist that I know, of a small study a couple of years ago (I think from the Netherlands but not sure

) which suggested Enbrel *appeared* to be
inducing new onset iritis in a very small subset of the AS patient population, even though at the same time it was proving to help prevent iritis attacks in so many. While it was not iritis in your case, I do wonder if it's a related type of reaction. At that time, it did not appear to be the true for those on Remicade and the jury was still out on Humira, (as the numbers were simply too small at the time) but I have not heard or read anything further on this since.
Given that a few years has passed, I wonder if clearer data exists now, that your Rheumatologist might have access to? I think it's quite possible that Remicade may not cause the same trouble, as it appears to be more effective against iritis than Enbrel... but then again, the optic nerve is a different thing, and the degree of risk might differ too in your individual case. Anyway, I mention it only on the off chance it might be an option worth exploring with your doctor, if you live in an area with access.
Gosh, it must be terribly disappointing for you. I know for me I'd be downright panicked and depressed, if for whatever reason, I had to face going off Remicade, but can only cross my fingers and hope.
I wish you the very best in finding a helpful treatment that will also safeguard your eyesight.
