The First Symptoms Of Non-Multiple Sclerosis – Vision
The optic nerve leads from the back of the eye to the brain, sending images of electrical discharges that the brain can interpret as light entering the eye.
What is optic neuritis (ON)?
Optic neuritis is an inflammation of the optic nerve that can cause partial or total loss of vision. In some people, these types of conditions are early signs of multiple sclerosis Australia, which causes inflammation and damage to the nerves of the brain and spinal cord.
Symptoms of optic neuritis
Symptoms may include loss of colour, image washing and eye pain. This condition can occur in one eye or simultaneously or alternatively.
Pain: There is usually pain associated with ON, which increases when there is eye movement.
Visual loss: visual loss varies from person to person. Some people may have severe, blurred vision loss or wash their eyes, while others may not feel any changes at all. Vision loss can occur from one day to a week and can be temporary, but in some cases, it can be permanent.
Colour loss: may affect red and green colours, reduce the sharpness of images and affect blurry colours. Optic neuritis develops very quickly and can occur for several hours, and some have complained that it is common for it to develop for days due to blurred vision.
People at risk of optic neuritis
Optic neuritis can affect people of all ages, but those most vulnerable to this condition include:
Age: between 15 and 50 years.
Gender: twice as likely to occur in women
Race: Caucasians are more likely to suffer from optic neuritis.
Studies have shown that people who developed autoimmune disease, multiple sclerosis (MS), 15 years later, have several correlation results between ON and MS, according to various studies, and are considered one of the first signs of MS.
Causes of optic neuritis
As mentioned earlier, electrical stimulation travels through the optic nerve, allowing the brain to convert the stimulus into an image of the brain.
An optic nerve is a large number of nerves covered with myelin sheath, an adipose tissue that allows electrical stimulation to move rapidly to the brain. In two autoimmune conditions, this adipose tissue is attacked, which causes inflammation and damage to the optic nerve.
Multiple sclerosis: This condition is associated with the body’s attack on the myelin sheaths of nerves in the brain and spinal cord. As mentioned earlier, 50% of the cases in which MS developed after 15 years. This is the first signs of Ms (Multiple sclerosis).
Optical / Device’s Neuromyelitis syndrome: This condition affects the central nervous system, which affects the spinal cord and optic nerve. Again, the body attacks the myelin sheath that surrounds the optic nerve and spinal cord.
There are many causes of optic neuritis.
Infection: An infection or virus can cause ON, such as syphilis, HIV, hepatitis B or herpes.
Diabetes: people with diabetes have a higher risk
Cranial Arteries: Inflammation of the arteries in the brain, which can limit blood flow to the brain and eyes. Problems with blood flow can cause strokes or loss of vision.
Optic neuritis is usually diagnosed when the patient undergoes a vision test after complaining of pain in the eye or lack of vision. Optometrists who control vision receive regular eye exams along with certain tests to investigate their concerns. Optometrists refer to ophthalmologists to diagnose and treat the condition. You can also refer to a GP to investigate possible autoimmune diseases.
Regular eye exams should be done to determine your vision. If there is a change in vision, a vision test should be done as soon as possible.
