We report a 71-year-old male with microscopic polyangiitis (MPA) who developed sudden-onset, progressive, bilateral visual loss associated with a relapse of MPA symptoms. The patient was referred to our hospital, and treated with intravenous pulse steroid therapy and high-dose oral prednisolone. Although the right eye remained vision deficient, visual acuity in the left eye recovered. Ocular manifestations of MPA are quite uncommon. This case emphasizes the necessity of early detection and initiation of prompt therapy where ocular manifestations of MPA occur.
