Disorders of the nerves of the eye are small photoreceptors on the retina or on the inner surface behind the eyes, which feel the light and send signals to the nerves of the eye, then the nerve nerves carry signals to the brain.
Causes of Eye Nerve Disease
This problem anywhere along the optic nerve or damage to the area behind the brain, which perceives visual information can cause loss of vision or damaged eyes. The cause of damage to the eye’s nervous system is a tumor found in the pituitary gland pressing on the eye nerve.
Both eyes carry signals from the eye to the back of the brain, the brain is called optic chiasm , each nerve divides and half of the fiber crosses over the other side because of this anatomical structure or arrangement, the damaged nerve can cause a special pattern of vision loss.
The next question that might also be in your mind is what is the source or what causes this neurological disease?
Damaged eye nerve disease can be caused by several triggers, while the triggers include:
- Abnormalities in the eye
- Addition of eye fluid production from ciliary bodies
- Diseases that affect the eye nerves
- Exposure of eye fluids in the corner area of the eye chamber, can also be a pupil gap
- Side effects of consuming several kinds of eye nerve drugs
- Genetic factor or also called heredity.

Signs of Eye Nerve Disease
If you experience this neurological disease, then you will feel some of the following signs:
- Seeing neon lights or other light sources, you will see the rainbow color around the lamp.
- The eyes hurt when the eyes are swollen.
- The vision that had previously blurred over time returned to normal.
- The feeling of wanting to wink continuously, even the pressure on the blink usually becomes excessive.
Those are some of your signs of eye neuropathy.
Risk factors for eye nerve disease
Risk factors for developing neurological diseases of the eye include:
- Age . The eye nerve or optic neuritis most often affects adults aged 20 to 40 years.
- Sex . Women are far more likely to develop optic neuritis than men.
- Race . In the United States, optic neuritis is more common in white people than in blacks.
- Genetic mutation . Certain genetic mutations can increase your risk of developing optic neuritis or multiple sclerosis .

Complications of Eye Nerve Disease
Complications arising from ocular nerve diseases include:
1. Optic nerve damage
Most people experience permanent optic nerve damage after an episode of optic neuritis, but the damage may not cause symptoms.
2. Decrease in visual acuity
Usually it will return to normal or close to normal vision in a few months, but the loss of some color vision problems may persist. For some people, vision loss persists after optic neuritis improves.
3. Treatment side effects
Steroid drugs such as steroids used to treat optic neuritis will reduce your immune system, which causes the body to be more susceptible to infection. Other side effects include changes in mood and weight.
Weak Eye Nerves
There is also a weak eye nerve. Usually a weak eye nerve in a person is characterized by minus eyes, low vision, and various other eye nerve disorders. This is a sign of damaged or weak nerve cells. Humans have 6 muscles that are useful in moving the eyeball in various directions. If the nerve muscles of the eye are weak, vision can be disrupted, in other cases you may also experience double vision.

Treatment of Eye Nerve Disease
The best way to cure the nerves of the eye is to avoid choosing careless therapy. However, it is better if you go to an ophthalmologist first.
You can ask the doctor to do an examination. Don’t forget to make a complaint clearly, so the doctor will not be misdiagnosed. Then the ophthalmologist will prescribe, vitamins for the nerves of the eye, or the best solution.
Improving nerve eyes or optic neuritis has changed in recent years, because of a series of studies known as Optic Neuritis Treatment Trials (ONTT).
In this study, people with ocular nerve disease were randomized to treat intravenous steroids (IV), oral steroids or placebo (empty drugs). After that they were evaluated for several years.
From this study, researchers learned that steroid treatment had little effect on the final visual results in patients with ophthalmic nerve disease.
However, patients treated with IV steroids had fewer recurrent eye nerve attacks than patients treated with oral steroids alone. In fact, those treated with oral steroids alone had a higher risk of recurring eye nerve attacks than those treated with placebo.
Even more importantly, patients who were initially treated with IV steroids had about half the risk of developing MS in two years as patients treated with oral steroids alone, or placebo. Of those treated with IV steroids (followed by oral), 7.5 percent developed multiple sclerosis (MS) in the following two years, compared to about 16 percent in the other group.
As a result of the ONTT, ophthalmologists now treat eye neurological patients with a combination of intravenous and oral steroids or monitor conditions without prescribing medical care. The use of oral steroids alone is not recommended.
For patients who are medically treated, treatment usually includes three days of IV steroids, followed by around 11 days of oral steroids.
