In some cases there may be a permanent reduction in sight, this is when continued episodes cause scarring on the optic nerve. The eye itself is usually sore to the touch. The pain generally begins at the same time as the visual loss and improves along with it.
Loss of color vision out of proportion to the loss of visual acuity is characteristic of optic neuropathies. The most common patterns of color vision loss in optic nerve disease are loss of red protanopia and green deutranopia. Most Common in Young Women Acute demyelinating optic neuritis most often affects women in their 20s and 30s.
Studies have estimated its annual incidence to be about 6 per , The incidence, just like MS, are higher in populations at higher latitudes and lower near the equator. It's also less common in blacks than in whites. In children, optic neuritis is not as strongly associated with MS, especially when there is optic disc swelling or bilateral involvement. A surprising fact is oral prednisone seems to increase the risk of recurrent optic neuritis and is not used. Enlarge by passing over or clicking image info This modified image is licensed by My-MS.
Original image attribution goes to Patrick J. Pain associated with optic neuritis usually peaks within one week and then goes away within several days. Some people experience severe difficulty seeing, while others might not notice any changes in their vision.
Vision loss, should it occur, usually develops over the course of a day to two weeks and may be worsened by heat or exercise. Vision loss is usually temporary, but it may be permanent in some cases. You may notice that the colors of objects, particularly red ones, temporarily appear "washed out" or less vivid than normal.
Long-term use of steroids may also cause osteoporosis. Optic Neuritis. Reading can become difficult, especially if the central portion of the visual field is affected. The optic nerve is the cable that connects the eye to the brain. In Optic Neuritis, there is inflammation of the covering of the optic nerve.
This covering is composed of a fatty substance known as myelin. When inflammation damages the myelin sheath, the optic nerve cannot properly transmit information from the eye to the brain and vision becomes decreased in that eye. Optic Neuritis most often occurs between the ages of 20 to 50 and is three times more frequent in women. In adults it affects only one eye in most cases, but in children it can affect both simultaneously.
The doctor will diagnose Optic Neuritis based on characteristic findings at the time of a careful examination. Some patients with optic neuritis will have mild swelling of the optic nerve and surrounding retina that is visible to the physician during examination with the ophthalmoscope.
However, most patients with Optic Neuritis will not have observable abnormalities of the retina or optic nerve because the inflammation in the optic nerve has occurred behind the eye itself. A computerized test can quantify the extent that the field of vision is reduced.
Reduced color vision is a common finding and is detected by tests for color-blindness. Uncommon symptoms and findings on examination should alert the doctor to search for other causes of visual loss. These other conditions include a stroke of the small arteries supplying blood to the eye, especially in older persons with high blood pressure or diabetes; other types of inflammation; infections; tumors compressing the optic nerve; genetic diseases; and other disorders of the retina.
Important signs that may suggest one of these other causes include an unusual time course for vision loss for example, progressive loss of vision lasting more than two weeks or failure to recover vision within 1 month , the absence of pain, or an eye exam that shows other abnormalities that are not typical for Optic Neuritis such as severe swelling of the optic nerve or visible bleeding within the eye.
Even if there are no symptoms other than the loss of vision, the brain MRI may reveal additional areas of prior inflammation in the brain, separate from the optic nerve, that reflect demyelination at other sites. Experts believe that patients that also have these additional areas of demyelination are found should be treated with medications that reduce the chance of developing symptoms of definite MS.
For most patients with optic neuritis, blood tests are of limited value. Content on this website is provided for information purposes only.

The optic nerve and optic neuritis The optic nerve is actually more than one million individual nerves bundled together. Symptoms of optic neuritis Symptoms of optic neuritis can include: blurred vision grey vision colours seem faded dim vision pain in the back of the eye, especially during eye movement. Causes of optic neuritis Some of the many conditions and diseases that can cause optic neuritis include: cytomegalovirus hepatitis B herpes HIV Lyme disease measles multiple sclerosis mumps paranasal sinus infection radiation therapy syphilis tuberculosis.
Optic neuritis and multiple sclerosis Optic neuritis can be the first symptom of multiple sclerosis MS , but this is only true for some people. Diagnosis of optic neuritis Optic neuritis can be mistaken for a number of other eye conditions such as ischaemic optic neuropathy, so careful diagnosis is important. Tests may include: eye examination colour vision tests peripheral side vision tests — to test visual field MRI scan — this scan is helpful to diagnose the condition and also to give information that will be able to assess the risk of the person developing MS.
Subclinical optic neuritis A person may have demyelination of the optic nerve but not experience any visual symptoms. Treatment for optic neuritis Permanent damage to the optic nerve occurs in about 85 per cent of cases, but the damage does not always cause serious vision problems.
