Optic Neuritis In the case of optic neuritis, the optic nerve becomes swollen, and its function is impaired. Inflammation of the optic nerve causes loss of vision because of the swelling and destruction of the protective myelin sheath that covers and insulates the optic nerve.

A to Z List of Neurological Disorders Devic's disease, or neuromyelitis optica, (NMO) is a type of inflammatory demyelinating disease. A demyelinating disease occurs when the myelin sheath, a protective covering that surrounds brain and spinal cord nerves is damaged. In the case of Devic's disease, the patient develops myelitis (inflammation of the spinal cord) and optic neuritis (inflammation of the optic nerve).

The Optic Nerve “Optic neuritis” is an inflammation of the optic nerve. It may affect the part of the nerve and disc within the eyeball (papillitis) or the portion behind the eyeball (retrobulbar optic neuritis, causing pain with eye movement).

Neuromyelitis optica Currently two principal causes are accepted: 1  In NMO-IgG positive patients, the cause of the neuromyelitis optica (understood as the syndrome) is an autoimmune aquaporin-4 channelopathy, due to these specific autoantibodies. In these cases, astrocytes are the victims of the autoimmune attack.

Neuromyelitis optica (NMO), also known as Devic's disease or Devic's syndrome, is a heterogeneous condition consisting of the simultaneous inflammation and demyelination of the optic nerve (optic neuritis) and the spinal cord (myelitis). It can be monophasic or recurrent.evic's disease is more common in Asians than Caucasians. In fact, Asian optic-spinal MS (which constitutes 30% of the cases of MS in Japan) has been suggested to be identical to Devic's disease (differences between optic-spinal and classic MS in Japanese patients).

Optic neuritis: MRI of optic nerve Optic neuritis: MRI of optic nerve Save this for later. 2. Optic neuritis is the medical term that refers to inflammation of the optic nerve, one of the twelve cranial nerves in charge of transmission of light signal processed in the retina to specific portions of the brain (the occipital cortex).n the majority of cases, however, optic neuritis can be easily diagnosed according to clinical and ophthalmologic examination findings. MRI of the nerve is basically reserved for atypical cases when doctors are not sure whether the condition is actually optic neuritis or its resembles this type of inflammation.

- Optic neuritis is a demyelinating inflammation of the optic nerve. It is also known as optic papillitis and retrobulbar neuritis. It is most often associated with multiple sclerosis, and it may lead to complete or partial loss of vision in one or both eyes. Partial, transient vision loss can be an indication of early onset multiple sclerosis. Other possible diagnoses include: diabetes mellitus, low phosphorus levels, or hyperkalaemia.
