Hi there,
I think you'll get more responses if you post on
Birdshot Retinochoroidopathy Uveitis Forum

You may have come across it already but it is quite an active site for sufferers of birdshot. I don't know any better. I'm on Cellcept and Prednisolone and vision has improved. The trouble is maintaining it. The steroids are not fun but I've been OK on the Cellcept. Good luck. Adrian
