The optic nerve can be restored

Restoration of vision thanks to the regeneration of the optic nerve

According to a study published in the latest issue of The Lancet Neurology, the optic nerve can be repaired. The optic nerve has long been thought to be permanent, and damage to it is often associated with blindness or severe visual impairment. Once diagnosed, as with glaucoma patients, medication or surgery can help slow the progression of the disease, but it can only protect the remaining vision. Treatment is not sufficient to restore vision already lost due to nerve damage.
Scientists have known for many years that a form of human cell called a Schwann cell can be transplanted and regenerate myelin. Myelin is a substance that helps the nervous system function by creating electrical insulation around some nerve cells. Its damage causes the signals to malfunction or be distorted, which affects the senses.
In the case of the optic nerve, what is damaged or reduced is the person’s vision. Because the body’s natural inhibitors prevent the growth of the optic nerve, it is part of the central nervous system and cannot be repaired or fixed.

Axon regeneration in the central nervous system: insights from the optic nerve

Optic atrophy can be caused by various factors. The most common cause is lack of blood supply. The medical term for this disease is ischemic optic neuropathy. The problem mainly affects the elderly. Shock, chemicals, radiation, and trauma can damage the optic nerve. Atrophy of the optic nerve can also lead to eye diseases such as glaucoma. Diseases of the brain and central nervous system can also affect the disorder. These include: Children and young adults can also be affected by unusual forms of hereditary optic atrophy. Signs and symptoms
Vision decreases as a result of atrophy of the optic nerve and the field of vision decreases. In addition, the ability to see details is lost. The colors looked washed out. Over time, the pupil may become less responsive to light and gradually lose the ability to respond to light. Exams and Assessments
Symptoms of optic nerve atrophy are permanent. It is necessary to identify the underlying disease and treat it. Otherwise, loss of vision will follow. Diseases that cause visual atrophy can be treated in some cases. Outlook

07 blocked the experimental outflow for study

Updated July 7, 2016: A passing reader is wondering if there is stimulation of retinal ganglion cell axon proliferation after partial restoration of vision in mice, as this article appears to have appeared in search engines and attracted a lot of attention from patients. It’s an early and lukewarm victory, and you should read the fine print before you get too excited. However, progress is being made, but slowly.
I am sure that the body will heal itself and this is the most “normal” thing to do. The investigative procedure outlined here is accurate… and quite logical. The ability of nerve fibers to “…send to the correct visual centers…make contacts with other neurons…” is perfectly normal. I once heard at a spinal cord injury conference that once nerve fibers are severed, doctors and scientists have a hard time reconnecting them. I don’t see why it wouldn’t be natural for them to find themselves (and reconnect properly).

Optic neuropathy in the intestines has been treated with great success

The optic nerve is a bundle of nerve fibers that connects the retina to the brain, carrying electrical impulses. One end of this “wire” is a set of retinal cells called retinal ganglion cells. Retinal photoreceptors convert light into electrical impulses that are transmitted to retinal ganglion cells. Ganglion cells, in turn, send visual information to the visual centers of the brain through their axons. The electrical impulses are then converted into visual information. This flow of visual information is disrupted When the optic nerve is damaged.
Not at this time. The study of regeneration processes and how they can be activated is still in its early stages. However, a lot of interesting work is being done in this direction.
In some lower vertebrates, the optic nerve can regenerate. A damaged optic nerve, for example, completely regenerates in fish and frogs, allowing full vision to be restored. It has been shown that when retinal ganglion cells are exposed to conditions in the peripheral nervous system, they can successfully regenerate their axons.
