Durezol vs immunosuppressant therapy

Originally, I was diagnosed with APMPPE in 2017, and did not have uveitis, just the beginnings of an epiretinal membrane. Unfortunately, I developed uveitis within the past year, and my new Opthamologist has declared my condition to be Birdshot chorioretinopathy (as I now have tested positive for HLA-A29). I am on Durezol, and have been sent to a rheumatologist in order to receive Mycophenolate. Is this a normal procedure? Which medication works best for Birdshot/APMPPE (with fewer side effects)?
