A Case of Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease with Acute Bilateral Total Blindness

Myelin oligodendrocyte glycoprotein (MOG) an-tibody-associated disease (MOGAD) is a demyelinating disease of the central nervous system. MOG is a glycoprotein located on the surface of oligodendrocytes that acts as a cellular adhesive molecule in the central nervous system. The role of MOG has not been fully elucidated, but it is known to regulate microtubule stability and mod-ulate myelin-immune interactions by mediating the complement cascade [1]. MOGAD clinically presents with optic neuritis, transverse myelitis (TM), or rarely, acute disseminated encephalomy-elitis (ADEM), depending on the location of the lesion. The clinical manifestations of MOGAD differ by age. Younger children mostly present with an ADEM phenotype.
