Demyelinating Optic Neuritis in Children

Abstract

Acute demyelinating optic neuritis in children can occur in isolation or be associated with acute disseminated encephalomyelitis, multiple sclerosis, or neuromyelitis optica. Clinical features, neuroimaging, cerebrospinal fluid findings, and long-term prognosis were reviewed in 26 children diagnosed with optic neuritis at the first presentation of demyelinating disease. The risk factors for the subsequent diagnosis of multiple sclerosis were analyzed. The mean duration of follow-up was 6.2 years. To date, 6 children have been diagnosed with multiple sclerosis (23%). An abnormal brain magnetic resonance imaging, older age, oligoclonal bands in cerebrospinal fluid, and elevated immunoglobulin G index were associated with multiple sclerosis outcome. Children with monosymptomatic optic neuritis and an abnormal brain magnetic resonance imaging had a higher risk for multiple sclerosis. These children should be monitored closely for the subsequent diagnosis of multiple sclerosis and can be considered for early preventive therapy.
