Optic Neuritis
Diagnosis of Optic Neuritis
A doctor's evaluation Usually magnetic resonance imaging Diagnosis involves examination of the reactions of the pupils and observing the back of the eyes with a light with magnifying lenses (ophthalmoscope). The head of the optic nerve at the back of the eye (optic disc) may appear swollen. Testing the field of vision usually reveals loss of a portion of the visual field. Magnetic resonance imaging (MRI) of the brain may show evidence of Multiple Sclerosis (MS) ; myelin oligodendrocyte glycoprotein antibody-associated disease (also called MOGAD), a neurologic, immune-mediated disease in which the optic nerve becomes inflamed; or neuromyelitis optica (also called NMO), a rare immunologic disease that damages the spinal cord and optic nerve. MRI of the brain and orbits will usually show abnormality of the optic nerve. Spinal cord imaging may be done in people with neurologic symptoms.
