Intravenous Immunoglobulin Treatment for Recurrent Optic Neuritis

Introduction Recurrent optic neuritis neuritis (rON) is an autoimmune inflammatory condition of unknown cause. Intravenous immunoglobulin (IVIg) treatment is used for many autoimmune disorders; however we do not have any information about its effect in rON, other than case reports. We aimed to evaluate our patients with rON who were treated with IVIg.
