Optic neuritis is a condition in which swelling and inflammation of the optic nerve leads to decreased vision, including worsening of visual acuity (clarity of vision), color vision, and field of vision.
Approximately one-third of children with demyelinating disorders of the central nervous system (CNS) may experience optic neuritis as a first symptom. In most cases, vision will return to almost normal, but subtle changes, including changes in color vision, and contrast vision may occur. These changes may accumulate over time.
A recent IPMSSG paper describes current knowledge regarding optic neuritis in children and describes treatment approaches for this condition.
