    Neuritis and vision

    Optic neuritis - an inflammation of the nerve. Optic nerve - this is the main nerve of the eye. It directly connects the body of the brain. It is for him steadily obtained visual information is transmitted.

    Many of us, probably, from their own experience oran example of close friends had to know what neuritis. The most common are neuritis of the facial nerve, intercostal nerves or the hands and armpits. Who at least once in his life faced with a similar ailment, he is well aware that he is associated with extremely intense pain. Fortunately, this does not apply to optic neuritis. The disease usually is not accompanied by pain (the optic nerve is not adapted to transmit "pain" information). But the disease has different symptoms.

    As we know, is always accompanied by inflammationreduction function that is inflamed. In this case, some of its functions will be to lose the optic nerve. And these functions - to transmit information to the brain. Therefore, if they are violated, the resulting brain "picture" will suffer. Therefore, the main symptom of optic neuritis - blurred vision.

    Calling neuritis are a variety of reasons. During severe infection pathogen may be a bacterium or a virus (staphylococcus, pneumococcus, influenza, syphilis and others.). Thus bacteria or viruses, extending through the body embedded in a nerve or its shell (this can be done not only bacteria, but their toxins) and cause inflammation.

    It should be noted that some diseases, e.g.angina, can lead to optic neuritis indirectly. The pathogen causing the sore throat, will not apply. However, inflamed tonsils are sending a massive flow of nerve impulses to the brain, and this stream can "turn off" the signal transmitted by the optic nerve. Besides, the optic nerve can start to adequately respond to erratic flow pulsation, whereby its membranes edema occurs, that is, in fact, inflammation is triggered. In addition to viruses and bacteria, the cause of neuritis may be a variety of metabolic disorders (gout, diabetes and others), and systemic diseases (such as diseases of the blood system, some kidney diseases).


    How do I know optic neuritis

    As already mentioned, the main symptom of neuritisoptic nerve - blurred vision. It is, as a rule, only one. The distortion of the image appears the loss of sharpness, clarity. The outlines of objects blurred. Very often there is the phenomenon of "tunnel vision" (no peripheral vision, look like going through a long tube). Also very common symptom of optic neuritis is loss of perception of any color (a kind of sudden attack of color blindness). Sometimes described painting complement dark spots, which are located arbitrarily in sight. As these symptoms very similar neuritis inflammation of the retina (retinitis). However, if the retinitis is characterized by sudden, lightning-fast rise symptoms like "lightning strike" in the midst of a "full health", when neuritis symptoms increase slowly, almost always within a few days (not hours). In any case, the final diagnosis can put the doctor after instrumental examination (study of the fundus).

    Fighting for sight

    Optic neuritis - a dangerous disease,requiring extremely serious approach. The treatment uses a common set of powerful anti-inflammatory agents. In the first place - hormones as drops and ointments rarely - in the form of injections. Furthermore, paracetamol applied Efferalgan other.

    Very important is the recoveryperiod. When the acute inflammation has subsided, the regenerative processes begin on the site of the pathological focus. They often lead to the formation of the scar, and this, in turn, will block or permanently damage the "channel" (the optic nerve). To the scar is not formed, it is actively used the so-called "resolution therapy ', which is the appointment of a wide range of vitamins (especially those that are needed nerve, - B and PP) in the form of droplets and electrophoresis. Appointed as vasodilator drug (if vessels are dilated, so the nerve supplied with blood better, and hence cell death and replacement by scar will not happen).

    Widely used autohaemotherapy (introduction of own blood taken from a vein, intramuscularly in the buttock), however, it is most effective in the fight against it with bacterial - viral lesions.

    If treatment is initiated in a timely manner and held infull, then the vast majority of vision in the affected eye can not recover (though sometimes there is a certain decrease). Otherwise (if the treatment is too late) atrophy and can not stop, unfortunately, the eye can cause blindness.
