Vogt-Koyanagi-Harada (VKH) disease is a multisystem syndrome characterized by ocular (uveitis and retinal detachment), neurological (headache, tinnitus, and meningitis), and integumentary (vitiligo, alopecia, and poliosis) involvement. Although the pathogenesis of VKH disease is not well understood, an autoimmune T-cell response to a melanocyte-associated antigen is considered to be a cause of VKH disease. The complex immunological response to interferon and ribavirin may induce or exacerbate the autoimmune condition; however, VKH disease is a very rare complication associated with interferon therapy in chronic hepatitis C. We report a case of VKH disease occurring during pegylated interferon-alpha2b and ribavirin combination therapy for chronic hepatitis C.
