The Use of Optical Coherence Tomography and the Multifocal Electroretinogram to Distinguish Optic Neuritis from Retinopathies

Optic neuritis is an inflammatory demyelinating disorder of the optic nerve, a common cause of vision loss among patients withmultiple sclerosis. Vision loss, the presence of a relative afferent pupil defect, visual field defects, dyschromatopsia and a normal fundus examination are common presenting clinical manifestations. Retinal disorders may mimic optic neuritis, and the distinction between optic neuritis and some retinopathies may be difficult on clinical grounds alone.
