Patients with optic neuritis generally experience severe symptoms, as failing to receive appropriate treatment can lead to a significant and potentially irreversible decline in vision, resulting in disability. It is recommended that patients with optic neuritis be hospitalized for treatment. Hospitalization is necessary to carry out various supportive tests, including lumbar puncture lab tests and comprehensive MRI scans. Treatment of optic neuritis also involves administering high doses of corticosteroids based on the patient's condition. It is difficult for patients to manage such high doses of corticosteroids at home. Moreover, doctors need to closely monitor for any adverse reactions caused by these steroids. Therefore, hospitalization is advised for the treatment of optic neuritis, as the risks and prognosis are considerably worse without it.
