damaged optic nerve

El optic nerve It is a very important part of the eye, as it is in charge of connect the eyeball with the part of brain that processes visual information.

Thanks to optic nerve, considered the second of the twelve cranial nerves, is transport correctamente visual stimuli What does the retina receive? for the brain to transform them into images.

El good condition of the optic nerve is essential for enjoy one good vision, Ya que any damage that you can present is considered serious and urgent since can cause partial or total blindness.

El good condition of the optic nerve is essential for enjoy one good vision, Ya que any damage that you can present is considered serious and urgent since can cause partial or total blindness.

What is the optic nerve?

There are a total of twelve pairs of nerves that are responsible for communicating between the brain and different parts of the body. The optic nerve is in charge of communicating the eye with the brain.

This nerve It is made up of more than 1 million fibers. and part of the optic disc that lies on the retina.

Optic nerve is divided into four parts known as intraorbital, intraocular, intracanalicular e intracranial.

La optic nerve length is 5 centimeters and its tissue does not regeneratefor this reason the damaged optic nerve is a condition that can cause irreversible blindness.

What is the optic nerve for?

El optic nerve It is a fibrous part of the ocular structure that essential for vision of the images.

The retina is the light-sensitive tissue of the eye where they project the images, and it is where nerve impulses are produced that are carried by the optic nerve to the brain, specifically to occipital lobe, to make vision possible.

In other words, the optic nerve connects the eyes to the brain, allowing the images taken on the retina of both eyes to reach the correct place in the brain to be interpreted.

Any process I can causing damaged optic nerve can put a person's vision at risk.

Causes of damaged optic nerve

El Damaged optic nerve can be caused by different infections or trauma which are studied by a branch of medicine known as neurophthalmology.

Some of the company's most common causes may damage the optic nerve, we find:

Glaucoma

El glaucoma It is a disease that occurs when increases intraocular pressure and damages the optic nerve progressively. As the nerve deteriorates, the loss of vision is greater.

Druses 

Our drusen are cellular debris and debris that the body is not able to eliminate through the bloodstream. The drusen vision loss appears progressively and, if optic nerve is affectedwill have a significant impact on central vision

Optic neuritis

This condition occurs when inflames the optic nerve by an abnormal blood supply within the ocular structure. He optic nerve damaged by optic neuritis is associated to conditions of immune system and multiple sclerosis and radiation exposure y toxic agents.

Accidents or injuries

Any eye injury caused by a accident can significantly affect the structure and damage the optic nerve.

Symptoms of damaged optic nerve

The appearance of symptoms indicating damaged optic nerve it can be quick and sudden.

The main symptoms are: 

  • Lost partial or total Of vision.
  • Damage to the optic nerve between an eye and the optic chiasm, area where the two nerves meet
  • Eye pain when you move your eyes.
  • If damage to the optic nerve has occurred in the chiasm, it occurs loss of peripheral vision.
  • Darkened vision o loss of gloss the environment or objects. 
  • Altered color vision.
  • Appearance of light flashes in the Campor visual

How do you make the diagnostic

To diagnose the damaged optic nerve, it is necessary for a specialist in neuro-ophthalmology to carry out an in-depth study of the ocular structure, which must include the following diagnostic tests: 

  • La visual acuity measurement from near and far. 
  • A campimetryWhich enables analyze if peripheral vision has been lost of the campor visual The campImmetry is one of the best diagnostic tools to detect whether there is optic nerve damage due to glaucoma. 
  • The exploration of fundus of the eye through a ophthalmoscopy
  • The study of muscle movements Of the eye. 
  • A optical coherence tomography for Obtain sectioned images of all the parts that make up the ocular structure, including the optic nerve. This scan allows examine the papilla, area of ​​the retina where the nerve starts.

Damaged optic nerve treatment

El treatment of the damaged optic nerve depends exclusively of the condition that caused the injury.

The damaged optic nerve is a delicate condition, since It is often irreversible to repair the damage. so that the patient recover vision.

Therefore, it is extremely important to go to the ophthalmologist immediately in case of presenting any of the symptoms of the damaged optic nerve described above.

Glaucoma

In case of submitting a optic nerve damaged by glaucoma, the key is in monitor intraocular pressure levels to avoid that the nerve continues to be damaged quickly and irreversibly.

In any case, the early diagnosis of glaucoma is key since it is the best tool to prevent damage to the optic nerve and total loss of vision.

Drusen and macular degeneration

Our drusen are one of the main Cause of macular degeneration, a condition that can significantly compromise the optic nerve and the central vision.

Fortunately, there are currently drugs that help stop the progress of this disease to offer a better quality of life to the patient.

Optic neuritis

To withdraw from your treat the optic nerve for optic neuritis It is important to address the cause of this condition early and it will depend on the cause that is causing the neuritis.

Multiple sclerosis and other diseases

Other diseases such as multiple sclerosis currently have treatments that allow reduce symptoms and disease progression.

Although sclerosis does not have a definitive cure, the patient can be offered alternatives that help him to control the disease and prevent total vision loss

El treatment of the damaged optic nerve will depend on the patient's state of health arriving, in some cases, to opt for a treatment that allows some vision to be restored.

Unfortunately, sometimes the damage is irreversible and you only get prevent further vision loss.
