Objective: To explore the clinical characteristics and prognosis of chronic relapsing inflammatory optic neuropathy (CRION). Methods: A retrospective analysis was conducted. Clinical features, disease course, prognosis and magnetic resonance imaging (MRI) of patients with CRION who were admitted to Department of Neurology between 2014 and 2016 were reviewed and analyzed. Results: Totally, there were 27 patients (10 males and 17 females), with an age range of 17-59 years. The disease duration was between 40 days and 8 years. There were 2 to 9 CRION episodes. The mean frequency of CRION episodes was 3.30±1.56. The outcome of visual acuity showed that the more episodes frequency was, the worse outcome became. There was 25 abnormal optic nerve signals in MRI. And in 22 cases, the abnormal signals were in intraorbital segment or inner pipe section. The antinuclear antibodies (ANA) titers were elevated in 5 patients. Five cases relapsed during reduction or withdrawal of steroids, but steroids was not added in time. The final outcome of these 5 patients was poor. Conclusions: CRION was more common in female than male patients. Most patients were companied by pain, and the lesions were more common in the intraorbital segment of optic nerve. The more episode frequency was, the worse prognosis became. If a relapse happened, steroids or other immunosuppressive agents should be used.
