Optic neuritis occurs when swelling (inflammation) damages the optic nerve — a bundle of nerve fibers that transmits visual information from your eye to your brain. Common symptoms of optic neuritis include pain with eye movement and temporary vision loss in one eye.
If you have optic neuritis, your pupils won't constrict as much as pupils in healthy eyes would when exposed to light. Other tests to diagnose optic neuritis might include: Magnetic resonance imaging (MRI).
La neuritis óptica se produce cuando la hinchazón (inflamación) daña el nervio óptico, un conjunto de fibras nerviosas que transmite la información visual del ojo al cerebro. Los síntomas comunes de la neuritis óptica incluyen dolor con el movimiento del ojo y pérdida temporal de la visión en un ojo.
It occurs when the body's immune system reacts against its own cells. This happens mainly in the optic nerves that connect the retina of the eye with the brain and in the spinal cord. But it sometimes occurs in the brain.
Healthcare professionals confirm that symptoms were caused by a typical attack type, such as optic neuritis, transverse myelitis or acute disseminated encephalomyelitis (ADEM). MOGAD also is diagnosed after the MOG-antibody is found in the blood or spinal fluid.

In the central nervous system, the myelin sheath protects nerves in the brain, spinal cord and nerves leading to the eyes, known as optic nerves. When the myelin sheath is damaged, nerve impulses slow or even stop.
