Diagnosed With Uveitis 2 Years Ago...idiopathic. Put On Prednisone Drops

Diagnosed with uveitis 2 years ago...idiopathic. Put on prednisone drops that seemed to help for awhile, however my pressure went up. Dr switched drop to Lotemax. Now the inflammation, pain, and redness are back. My Dr mentioned injections into the eye (which makes me nauseated thinking of) I just want to know if what my Dr's course of treatment is what I should be receiving?
