It can be applied to the eyelids alone or as part of the body and facial eczema. Caused by chronic conjunctivitis, valgus or dacryocystitis secretions or tears often irritate the skin of the eye. Children with adenosis and malnutrition are prone to occur, often with vesicular conjunctival keratitis. Clinical manifestations generally have a certain degree of regularity. The main manifestation of the disease is redness and swelling of the eyelids. A large number of blood rashes, blisters, erosions, and scarring are formed locally. When secondary infection occurs, pustules are formed, dislocated and healed, and the range can be extended to the face, forehead, etc., but It can also be changed from acute to subacute and chronic. The skin of the ankle is rough and hypertrophy. It is mossy, with scales falling off on the surface, and pigmentation. If it continues to contact with sensitizing substances or drugs, exudative conjunctivitis can still occur. , corneal surface infiltration, edema and other complications. basic knowledge Sickness ratio: 0.5% Susceptible people: no special people Mode of infection: non-infectious Complications: edema, conjunctivitis
Cause
Causes of eyelid eczema
Cosmetic factors (45%):
Topical application of sensitizing substances, such as penicillin, sulfonamide, atropine, iodine, mercury, pilocarpine and other ophthalmic drugs, or long-term use of cosmetics, metal glasses shelves (so-called glasses eczema).

It can be caused by sleeping pills, sedatives, sulfonamides, antibiotics, quinine, iodine and sodium salicylate. Others eat certain animal or plant proteins such as fish, shrimp, meat, milk, eggs and shells. Plants such as pods can also cause eczema of the ankle.
Other factors (15%):
Due to chronic conjunctivitis, secretions or tears during valgus or dacryocystitis often cause eye irritation. Children with adenosis and malnutrition are prone to occur, often with vesicular conjunctival keratitis.

Prevention
Eyelid eczema prevention
Prevention: The disease occurs in the summer, and there are multiple allergies. The incidence of infants and young children is higher than that of adults.
1. Remove the cause
(1) Although the cause of eczema is not easy to be clear, we should still ask for a detailed history, conduct necessary systematic examinations, try to find possible causes and remove them.
(2) People with allergies should not only avoid contact with substances that are allergic to allergies in food, clothing, housing, etc., but also strengthen physical exercise to improve allergies.
2. Avoid stimulating factors
Once eczema occurs, as a patient, try to avoid irritating factors, including scratching, boiling water, soap scrubbing, drinking and spicy food, so as not to aggravate the condition of eczema.
3. Early diagnosis and early treatment
According to the clinical itching severe, pleomorphic damage, tendency to exude, good limbs flexion and easy recurrence, easy to diagnose. For densely distributed red papules, herpes, with severe itching, should be treated early. Since most of the early eczema belongs to the acute phase or the subacute phase, the external drug treatment should follow the corresponding principle.
4. Allergic constitution or family history of allergies, to avoid a variety of external stimuli, such as hot water scalding, scratching, sun exposure, etc., try to avoid sensitizing and irritating food.
5. Life should be regular, pay attention to work and rest.
6. Clothing should be loose to reduce friction and stimulation, and do not allow chemical fiber and wool to directly contact the skin.
7. Eczema, especially chronic ones, are mostly not cured after years of treatment, and patients often lose confidence. In fact, eczema is not an "incurable disease", because the cause of the disease is extremely complicated, which brings difficulties to treatment. Patients should work with a doctor to build a cure.

Eyelid eczema complications Complications, edema, conjunctivitis
The skin of the ankle is rough and hypertrophy, and it is mossy. There are scales on the surface, and there may be pigmentation. If you continue to contact with sensitizing substances or drugs, complications such as exudative conjunctivitis, corneal surface infiltration, and edema may occur.
Symptom
