Despite having similar severity of neuroaxonal injury, children with MOG-IgG optic neuritis show better visual recovery than adults, as measured by various assessments including visual acuity tests, visual field tests, color vision tests, multifocal visual evoked potential (mVEP), and optical coherence tomography (OCT) (11) which provides structural information about the retina, indirectly related to predicting visual recovery. Here, MOG is linked to optic neuritis.
