News » Optic neuritis: how it affects you and how to intervene in time
Not everyone knows that the inflammatory processes that affect our body, to another more and more widespread and frequent in recent years, can also affect our eyes and, in particular, the optic nerve.
Among the cases of inflammation dependent on that part of optic neuritis.
This disease is to hit precisely the optic nerve, the bundle of ocular nerve fibers that play a key important role: transmit visual information to the brain.
As "behaves" optic neuritis?
Generally optic neuritis involves only one eye, however, although more rarely, it can be manifest in a bilateral manner.
In older patients, this condition can also be present as "ischemic optic neuropathy," in arteritic form (with higher ESR values) or non-arteritic (with less high ESR values): these two types cause a sudden loss of vision, often disabling.
The most common symptoms of optic neuritis are represented, more particularly, from different visual disorders such as altered perception of colors, an image blur, pain in the eye movement and periocular pain. Some subjects in general, claim to accuse visual phenomena such as perception of light flashes in the dark, spots in the vision, flashing lights, etc.
To this can be added the main symptoms, the arteritic form, symptoms such as headache, pain when chewing, the joints and, in some cases, even the scalp pain.
Causes and scientific field studies
On optic neuritis have focused, in time, several acts studies to criticize and find out the causes and origins of such an invasive disease.
In light of these, it was found that multiple sclerosis certainly represents one of the main causes of retrobulbar optic neuritis indeed, the presence of such neuritis is often one of the first signs of this disease. As regards instead the ischemic optic neuropathy, it is generally vascular nature.
However, even today, the exact cause - assuming there is in fact a - of optic neuritis is unknown. What is certain is that it goes to develop when the immune system mistakenly attacks the substance that covers the optic nerve (myelin), causing inflammation and damage to the myelin itself. Myelin, in fact, in the normal, allows electrical impulses to travel from the eye to the brain quickly.
So, in the brain, these impulses are transformed into visual information.
The optic neuritis causes a disruption of this process, affecting the vision in this way.
Subjects most affected and therapy
Optic neuritis most often affects young people aged between 20 and 30 years.
Of course the first step to diagnose correctly the disease is to consult an ophthalmologist.
These will surely be to examine the fundus to encounter any bulging and possible presence of bleeding at the optic nerve head (papilla).
Even a complete clinical and medical exam can help rule out any related diseases, given the fact that the optic neuritis can be an early symptom of other diseases.
Therapy related to optic neuritis
With regard to the therapy, for the treatment of ischemic optic neuritis retrobulbar arteritic and that it involves the use of systemic steroids, initially intravenously.
And \'early detection crucial: the treatment should be performed as soon as possible to try to limit the damage. In arteritic form, for example, which oftentimes it is often characterized by poor visual recovery, adequate therapy tends to strongly reduce the risk of a similar episode in healthy eye load.
