Anti-myelin oligodendrocyte glycoprotein antibody associated neuromyelitis optica spectrum disorder presenting homonymous hemianopia

ABSTRACT

@#Anti-aquaporin 4 antibody is the most common cause of neuromyelitis optica spectrum disorder (NMOSD) and anti-myelin oliogodendrocyte glycoprotein (MOG) antibody recently has emerged as another cause of NMOSD. Visual field defect can be observed as a manifestation of optic neuritis in patients with multiple sclerosis and NMOSD. However, homonymous hemianopia associated with a visual cortex lesion has been rarely reported in patients with multiple sclerosis and anti-aquaporin 4-positive NMOSD. Recently, we experienced a case of MOG-positive NMOSD who presented with a homonymous hemianopia associated with a visual cortex lesion
