What is neuro optic myelitis?
Neuromyelitis optica (NMO), also known as Devic’s disease, is a rare condition where the immune system damages the spinal cord and the nerves of the eyes (optic nerves). NMO can affect anyone at any age, but it’s more common in women than men.
What are the symptoms of neuromyelitis optica?
Neuromyelitis optica can cause blindness in one or both eyes, weakness or paralysis in the legs or arms, painful spasms, loss of sensation, uncontrollable vomiting and hiccups, and bladder or bowel dysfunction from spinal cord damage. Children can have confusion, seizures or coma with NMO .
Can transverse myelitis affect your vision?
Transverse myelitis associated with neuromyelitis optica usually affects both sides of your body. In addition to transverse myelitis, you may experience symptoms of damage to myelin of the optic nerve, including pain in the eye with movement and temporary vision loss.
Is neuromyelitis optica the same as optic neuritis?
Neuromyelitis optica (NMO) is an autoimmune demyelinating disease associated with recurrent episodes of optic neuritis and transverse myelitis, often resulting in permanent blindness and/or paralysis.
Can nerve damage affect eyesight?
The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs.
Is NMO always fatal?
Some people develop life threatening complications from NMO. One small study found that about 1 in 5 people with NMO develop breathing difficulties. Those breathing problems may require treatment with a ventilator. Fatal respiratory failure sometimes occurs.
What is the most common optic neuropathy?
The most common acute optic neuropathies include ischemic optic neuropathy (ION), optic neuritis and trauma. In patients ages 50 and up, acute anterior ischemic optic neuropathy (AION) is the most common presentation. AION is divided further into non-arteritic (NAION) and arteritic (AAION).
Which is worse NMO or MS?
Symptoms of NMO are usually severe than multiple sclerosis (MS). The individual episodes in NMO are more serious compared to MS. Their cumulative effect will have debilitating, irreversible effects on nerve functions.
Does optic neuritis always mean MS?
You may have vision problems in the future if you have optic neuritis but don’t have MS or another underlying condition. Your prognosis for improved long-term vision is better than if you do have MS, however. Having both optic neuritis and MS may make you more likely to experience recurring symptoms of optic neuritis.
What is neuromyelitis optica spectrum disorder?
Neuromyelitis optica spectrum disorder (NMOSD), also known as Devic disease, is a chronic disorder of the brain and spinal cord dominated by inflammation of the optic nerve (optic neuritis) and inflammation of the spinal cord (myelitis).
What is the difference between optic neuritis and transverse myelitis?
Optic neuritis: inflammation of the optic nerve (this carries information from your eye to your brain ). You might feel sudden pain inside your eye. That can be followed by problems like not seeing clearly or even blindness. It usually happens only in one eye, but it can happen in both. Transverse myelitis: inflammation of the spinal cord.

What are the signs and symptoms of transverse myelitis?
A variable degree of sensory loss may occur. Affected individuals may also have a stiff neck, back or limb pain, and/or headaches. This syndrome may be indistinguishable from other cases of “idiopathic” transverse myelitis.
