    developing keratitis

    Keratitis - an inflammatory disease of the cornea- Transparent consisting of finely matched surprisingly collagen fibers, which is a piece of glass hour limits front eye. Keratitis is accompanied by gross violations of not only the mirror surface of the cornea, but also deeper located tissue.

    Swelling and other symptoms of inflammation docornea rough, thickened. And gradually dying cells rejected its exterior, and finally decays corneal fibers and their replacement with scar tissue rough opaque. Once the inflammation subsides, the site of an inflammatory focus is formed blurred. His intensity and dimensions can be varied from undetectable, as the doctors say, oblachkovidnogo haze, barely, to flagrantly violate view, becoming a cause of blindness. You've probably ever seen a man with a thorn in the side. So cataract - this is the outcome of severe keratitis.



    Causes and types of keratitis

    Types of keratitis: Know the enemy in the faceThe main thing with keratitis - a single day delaya visit to a specialist. Each missed day threatens more intense infiltration of inflammatory focus in the cornea, and thus more severe scarring or lesions larger area. Increasing the inflammatory focus even one millimeter toward the center of the cornea can become a cause of irreversible vision loss. In rare cases, the entire dramatic process of the inflammatory destruction of the cornea up to its perforation can run wild in just two or three days!

    Causes of keratitis are very diverse. Most often it is an infection, which pathogens penetrate the corneal tissue by endogenous, that is, from the body, or exogenous - from the outside.

    Endogenous keratitis can be causedchronic illnesses - tuberculosis, syphilis, brucellosis, herpes, diseases of the nasopharynx, teeth, as well as metabolic disorders, hypo- and beriberi, drug allergies.

    Exogenous cause keratitis falling outsidemicroorganisms - bacteria, viruses, fungi, as well as mechanical, physical or chemical trauma. Keratitis complicated by chronic diseases Century (blepharitis), conjunctiva (conjunctivitis), and lacrimal system (dacryocystitis).

    Keratitis usually makes itself felt immediately. Suddenly appear photophobia, lacrimation, conjunctival redness, foreign body sensation, pain in the eye. Sometimes these effects are so pronounced that the person can not open his eyes. If the inflammation is localized in the central part of the cornea from the first day significantly decreased visual acuity; foci of inflammation, which are located on the edge of the cornea, visual acuity did not initially affect.

    Almost all patients with keratitis need it inhospital treatment. The transmission of infection from patient keratitis healthy or sick keratitis caused by another cause, does not occur. Therefore, give up hospitalization for fear of infection is unreasonable!

    The most frequent (66.7%), herpetic keratitis, isthere is an inflammation of the cornea caused by herpes virus. Even 15-20 years ago about herpes infection knew very little, although its manifestations are familiar to everyone. Herpes is still colloquially called the fever, painful blisters which showers lips, nostrils, various areas of the skin, mucous membranes. The appearance of these vesicles on the cornea and subsequent ulceration - this is herpetic keratitis.
    Herpes is a striking feature,decoded by scientists only in recent years. Human Infection usually occurs during early childhood through the nasal and oral mucosa, usually without causing clinical manifestations. Virus settles in ganglia and usually remains in them inactive throughout life. But under adverse conditions to the body the virus can go into an active state and reaching the nerve pathways of the cornea, cause inflammatory disease. These adverse factors are disease influenza, malaria, tuberculosis, tooth loss, and paranasal sinuses, hypothermia, exposure to radiation, a long sun exposure, vitamin deficiency, stress, surgery, use of drugs that suppress the immune defense, such as corticosteroids.

    For a man who already had undergone acute keratitis,these factors are often the cause of disease recurrence. And herpetic keratitis is dangerous not so much the first attack, which can be very easy, as its recurrence. And they have been reported in 25-75% of patients. With each relapse of corneal clouding becomes denser, extensive, up to rough cataracts. With herpes infection is related to 60% of blindness caused by corneal lesions.



    Do not self-medicate

    The fate of the eye depends on the patient. Firstly, it is necessary, as already mentioned, immediate consultation with a specialist, who will assign specific antiherpethetical drugs in the form of drops, ointments, pills or injections. It should be borne in mind that the number of active antibacterial and even antiviral medications useless and, moreover, harmful by herpetic keratitis. That is why it is extremely dangerous to self. Thus, for example, antibiotics, high in bacterial keratitis, but uncontrolled used by patients with herpetic keratitis, can lead to a prolonged its current and serious complications. Even more dangerous use of corticosteroids patients: the first a false impression of a favorable impact they may turn severe complication, until the death of his eyes. Conversely, corticosteroids are prescribed by the doctor in the appropriate dose and at a certain stage of treatment - his brilliant assistants.

    Only one treatment reduces T-activin 3-4times the number of returns of the disease. On doctor's orders can be used and other methods. That's why all the suffering herpetic keratitis must be on long-term dispensary. It allows you to combine resolving restorative treatment (medication, physiotherapy, surgical) with courses of preventive treatment.

    If you scratched eye, speck got into it -immediately contact a doctor! Only a comprehensive drug treatment, and if necessary, surgery can help prevent disaster.
