Contact dermatitis and eczema eyelids

contact dermatitis and eczema eyelids - form of the disease, which occur much more frequently many other allergic eye suffering.Reflecting the reaction to a variety of external and internal factors, they differ in some features of the clinical picture and its dynamics.As a rule, these are manifestations of delayed type allergy is acute (dermatitis) or acute and chronic (eczema).The intensity of clinical symptoms and their variability, process acuity determined reactivity organism quality and quantity of allergens.

Causes contact dermatitis and eczema eyelids

first place among those take medications that cause drug dermatitis and eczema (drug reaction) used local anesthetics, mercury agents, ointment bases, designated locally, parenterally and into antibiotics, sulfonamides, salts of heavy metals,used inside barbiturates drugs bromine, iodine, etc., and quinine. In sum, they provide more than 50% of all allergic lesions of age.On the second place of the exogenous factors are cosmetic: dye eyelashes,

eyebrows and nails, creams, powders, lotions, some soaps.Dermatitis and eczema eyelids can also cause detergent, plastic products (frame or spectacle case, powder box, cigarette case, jewelery), industrial gases, dust, oils, solvents and so forth. With UV irradiation is associated fotoallergncheskaya eczema.Template, irrational use of drugs, self-medication, excessive use of cosmetics, detergents and other means, violations of industrial hygiene cause an increase in the frequency of allergic skin disease eyelids, as well as other parts of the body.

some importance in the development of dermatitis and eczema eyelids have food, epidermal, pollen, allergens and infectious autoallergens.Occurrence of disease contribute to skin degreasing century, it microtrauma, cracks, maceration discharge from the eye slit.Diseases are more common and severe in people who suffer from other allergic diseases or prone to them, burdened diathesis, etc.

The symptoms of contact dermatitis and eczema eyelids

Symptoms contact pathology age appear more frequently immediately after the impact of the stimulus, and after the incubation period,extending from 6-14 days to a few months or years.Many allergy becomes apparent only after repeated contact with the allergen.The patient can use for years in some medication, and suddenly his intolerance occurs.

Clinically, contact dermatitis to various allergens manifested developing acute skin erythema century, its swelling, soreness, rash of tiny papules and vesicles on the affected area.In severe cases red, swollen, hot to the touch or narrow the eyelids completely closed eye slit, there are conjunctival hyperemia, tearing or serous discharge, there may be cracks in the skin of the outer canthus.All this is accompanied by itching, burning sensation or a feeling of heat and often treated as acute eczema.The defeat is only limited to the skin of the lower eyelid, or both, or goes beyond them to the skin.The process is often reversible.Repeated exposure altered the skin age even with a minimum dose of the allergen causes the transition of dermatitis eczema.Of the same type when exposed to different allergens clinical picture is different at the same time a large polymorphism rash.The patient has intensified congestion, edema, and vesiculation of the skin age, having its maceration and Moisture, in which the centers are marked deepening point - eczematous or serous "wells", which stand out from the drops of serous fluid.Podsyhaya, exudate turns into a yellowish or whitish-gray crust, and devoid of the horny layer of the skin underneath remains congested and wet.

Of course, such a wealth of eczematous elements observed not every patient.The former scourge of the past for children and adults "blooming eczema" has now become rare even in oftalmopediatricheskoy practice.In adults, eczema is more often occurs without efflorescence and soak, limited only by the formation of flakes na moderately congested and edematous skin of eyelids, blurred ce surface layers.However, if the essence of the process remains unrecognized, the contact with the allergen continues, and worsens in severe cases, loss becomes similar to a burn during the illness.

When recovery is gradually reduced, moist areas covered by crusts, beneath comes epithelialization, and the skin is completely restored.The observed once the completion of eczema often cicatricial ectropion, their deformation, even elephantiasis in modern conditions can occur only at very unfavorable course of the disease.the same type of eczema clinic noted above when exposed to different allergens is not absolute.Depending on the nature of the stimuli AD Ado et al.(1976) distinguish true eczema, microbial, professional and seborrheic.A. Heidenreich (1975) describes an endogenous, parasitic, scrofulous and seborrheic eczema eyelids.Particular attention microbial and fungal eczema gives in his manual I. Merkulov (1966), whereas the YF Maychuk (1983) refers to this pathology as "eczematous dermatitis" and only mentions it in the labeling of medicinal allergies eyes.According to this author, the most common form of allergic skin lesions age is dermatokonyunktivit.Since allergy conjunctiva always in some way involved in the pathological process, with such a designation can agree, although it is less informative than those used for many years the concept of "dermatitis" and "eczema".

Unlike true "eczema Century" scrofulous and seborrheic its forms appear not only on the eyelids, but capture more extensive areas of the skin of the face and head, and their clinical eczematous elements are combined with the phenomena peculiar to scrofula and seborrhea.

Value infection in the pathogenesis and clinical eczema eye ambiguous.On the one hand, germs, fungal infection, other micro-organisms or their metabolic products may be allergens that contribute to the development of eczema eyelids.Clinic of eczema differs from other similar pathology only a clear demarcation of the affected skin from healthy, sometimes forming a sort of "fringe" exfoliated epithelium at the edge of the hearth.On the other hand, the infection can be laminated on the eczematous process and give it a pyogenic in nature: on the eyelids appear purulent exudate and crust.Most other infectious agents involved in the eczematous diseases Staphylococcus aureus.In addition to eczema, it is known to be causes of the disease ekzemonodobpye century, particularly ulcerative blepharitis.

Representing a delayed type allergy, eczema eyelids often occurs as a chronic inflammatory process, often with periods of significant improvement and relapse.With an average duration of illness 4-5 weeks rational treatment significantly accelerates recovery.On the contrary, new contacts with the allergen, diet violations, non-specific exogenous stimuli, mental stress, somatic pathology, unrecognized sources of endogenous allergens and autoallergenov contribute to the fact that the treatment does not give the desired effect and the disease lasts for many months.There is an acute, but with limited rash and quickly cease age of skin irritation is often interpreted in the literature as acute eczema, but are essentially allergic dermatitis.

Expressed identity and uniformity of the clinical manifestations of atopic dermatitis and eczema eyelids facilitate their nosological diagnosis and identification of allergens, in addition to allergic history and clinical trials, helping skin tests with prospective antigens.In spite of the seemingly limited only to defeat age, samples are often positive for distant from the eye of the skin.

Besides eczema eyelids that allergic genesis is indisputable, may develop this disease in patients with metabolic disorders (diabetes, gout, obesity), anemia, gastrointestinal diseases, with ariboflavinoze, overfed infants.Causes skin irritation age can also be a discharge from the eye slits in patients with conjunctivitis, constant tearing.However, in none of these cases can not be excluded allergic factors such autoallergens.
