Uveitis eye - a common name of inflammatory processes in different parts of the vascular membranes of the eyes (iris, choroid, ciliary body).
include inflammation of the eye at a fraction of uveitis (inflammation of the uveal tract) account for about 30-57% of diseases.Thus 25-30% of uveitis may lead to visual impairment, and even blindness.
The article describes the causes of uveitis, symptoms of the disease, as well as methods of conservative and radical treatment of uveitis eye.
Vascular (uveal) shell includes the iris, ciliary or ciliary body and the choroid (choroid, located under the retina).
Depending on the predominant position of the inflammatory process, there are the following forms of uveitis eyes:
greater prevalence of uveitis promotes what the eye vascular system is very branched, and, at the same time, blood flow inside it is rather slow.This leads to an accumulation of choroid various microorganisms causing inflammation.Another feature of vascular blood flow path is separate him of the anterior (iris and ciliary body) and posterior section (choroid).Blood supply of the anterior part is done by the front and rear of long ciliary arteries, and the rear division - back short ciliary arteries.As a result, the front and rear sections of the vascular tract usually affects separately, contributing to higher incidence of uveitis eyes.
Experts call many reasons uveitis.There are the following reasons.
1.Infektsii.The most common cause of uveitis eyes (44%).The causative agents of inflammation are streptococci, mycobacterium tuberculosis, pale treponema, toxoplasmosis, herpes simplex virus, cytomegalovirus, fungi.Infectious uveitis develop due to infection penetration into the bloodstream.They are often in sepsis, dental caries, tonsillitis, sinusitis, viral diseases, syphilis, tuberculosis.
2.Allergicheskie reaction.The cause of uveitis, allergic etiology is sensitive to environmental factors - hay fever, food and drug allergies.Sometimes this form of the disease develops with the introduction of some vaccines and serums.
3.Sindromnye and systemic diseases.Uveitis often appear in rheumatism, rheumatoid arthritis, psoriasis, spondylitis, sarcoidosis, multiple sclerosis, Reiter's syndrome, ulcerative colitis and other diseases.
4.Travmy.The cause of uveitis can be eye burns, foreign bodies entering the eye, contusion or penetrating damage to the eyeball.
5.Gormonalnaya dysfunction and metabolic disorders.There are many disease states that can become a cause of uveitis.Most often it is diabetes, menopause in women, diseases of eye, blood system diseases and other pathologies.
Symptoms of uveitis depend on the localization of the inflammatory process, the severity of the disease, the general state of the organism.
Anterior uveitis manifests itself in acute irritation, redness and pain of the eyeballs, contraction of the pupil of the eye, photophobia, lacrimation, deterioration of visual acuity.The patient often increases intraocular pressure.The symptoms of the chronic form of uveitis little pronounced.Most often the disease develops a little red eyes, flickering dots before his eyes.
In addition, a symptom of uveitis front of the choroid is the formation of corneal precipitates.The precipitates are a cluster of lymphocytes, plasma cells, macrophages, pigment "dust" that float in the chamber moisture.
Symptoms of uveitis periphery of the choroid is reduction of central vision, the occurrence of haze before his eyes.For this form of the disease is characterized by loss of both eyes.
There are symptoms of uveitis of the posterior choroid.Typically, the patient noted a decrease in visual acuity, "floating" point of vision, distortion of objects, blurred vision.In some cases, there is macular ischemia (severe disturbance of blood supply to the central part of the retina), macular edema (swelling of the central part of the retina), retinal detachment and other complications.
most difficult runs iridotsiklohorioidit - inflammation of the vascular tract eyes.Usually this form of uveitis develops in sepsis.She often accompanies Panophthalmitis (purulent inflammation of the eyeball) and endophthalmitis (purulent inflammation of internal tissues of the eyeball).
diagnosis of uveitis include an external examination by an ophthalmologist eye, visual acuity, pupillary reaction analysis, the definition of the boundaries of fields.In addition, the physician measures intraocular pressure.
Using special machines specialist conducts biomicroscopy (microscopy ocular tissues with the help of a slit lamp), gonioscopy (analysis of the front of the eye).
For accurate diagnosis of uveitis is usually used laboratory methods of research, such as RPR-test, determination of antibodies to major infections.
Complex treatment of uveitis consists of conservative therapy, surgery, physiotherapy.
When conservative treatment of uveitis is most often used broad-spectrum antibacterial action.In chronic course of the disease antibiotics conducts periodic courses.In addition, the patient is prescribed corticosteroids (anti-hormones).If it is impossible or ineffective use of corticosteroids, used immunosuppressants (medications that suppress the immune response).
Surgical treatment of uveitis, the eye is used for severe disease or the development of complications.Usually, when surgery is carried out treatment vitreous opacities, cut the front or rear of the iris adhesions (adhesions of the iris to the lens surface).
most frequently used treatment for uveitis physiotherapy techniques - laser irradiation of blood, and ultraviolet blood irradiation.These procedures significantly increase the bactericidal activity of the patient's blood.In the treatment of uveitis horioretinicheskoy forms are often used laser coagulation.
