Plasmapheresis as a viable treatment option for scleritis

PURPOSE: We describe a case and our experience with using plasmapheresis as a treatment for scleritis. OBSERVATIONS: Treating relapsing autoimmune scleritis can be challenging when it inadequately responds to traditional therapy. Our patient could not receive non-steroidal anti-inflammatory therapy for her scleritis due to recent gastrointestinal surgery and previously failed multiple steroid sparing treatments due to intolerance. There was good initial control with high dose oral prednisone, however, the steroid could not be tapered to a safe dosage (<10 mg per day) without relapse. Therefore, we opted to treat our patient with plasmapheresis. CONCLUSIONS AND IMPORTANCE: After undergoing plasmapheresis, our patient experienced total resolution of symptoms with corresponding clinical resolution of scleritis. Plasmapheresis derives great benefit by filtering circulating immune complexes. Although rarely used, plasmapheresis can be effective in treating non-infectious scleritis.
