We will review recent advances in pathophysiology, diagnosis, and clinical manifestations of MOG-IgG-associated optic neuritis to better understand its distinctive characteristics. RECENT FINDINGS: MOG is expressed on the surface of myelin sheaths and oligodendrocytes. MOG is highly immunogenic and is a potential target of inflammatory demyelinating disease. MOG-IgG activate immune responses and cause demyelination without astrocytopathy. MOG-IgG are measured by cell-based assays, which have higher sensitivity and specificity than ELISA. Patients with MOG-IgG-associated optic neuritis present with initially severe vision loss, are more likely to have optic disc edema, but have favorable visual outcomes. Furthermore, patients with MOG-IgG-associated optic neuritis have higher rates of recurrence compared with MOG-IgG seronegative patients. MOG-IgG-associated optic neuritis responds well to steroid treatment, however, close monitoring for signs of relapse and long-term immunosuppression may be necessary. SUMMARY: MOG-IgG associated optic neuritis demonstrates distinctive pathophysiological and clinical characteristics from optic neuritis in aquaporin4-IgG seropositive or multiple sclerosis patients. Measurements of MOG-IgG titers by cell-based assays will be helpful for the diagnosis and treatment of optic neuritis.},
