Neuro-Ophthalmology
Optic neuritis causes acute loss of visual function and can result in devastating visual dysfunction. Recently, measurements of anti-aquaporin 4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies have become available, making it possible to evaluate the disease pathogenesis. This paper...
