Itchy eyes, jealous, and secretions increase, the more itchy rubs ….. It is really miserable.Allergic conjunctivitis is the most common eye allergic disease. It is easier to attack in the summer and autumn allergies. The most typical symptom is itchy eyes.
What is allergic conjunctivitis
Allergic conjunctivitis is an inflammatory disease that conjunctuously generates allergic reactions to the external transformer. It is one of the common allergic diseases in clinical practice.Allergic conjunctivitis is usually divided into the following 5 types of sub -types: seasonal allergic conjunctivitis, perennial allergic conjunctivitis, spring corneal conjunctivitis, giant nipple conjunctivitis and characteristic keratinitis.Clinically, seasonal allergic conjunctivitis and perennial allergic conjunctivitis are more common.
The pathogenesis of allergic conjunctivitis
Allergic conjunctivitis is generally caused by the stimulation of allergens such as pollen, dust mites, fungi, animal hair such as pollen, dust mites, fungi, and animal hair.
According to the disease characteristics and clinical manifestations of this disease, Western medicine divides it into type I surreal and type IV surreal reactions.The mechanism of the type I hyper -allergic reaction is to combine allergens and IgE antibodies to activate hypertrophic cells to release histamine, tended factor, prostaglandin D2, white trotine, platelet activation factor, etc. These media synergy causes capillariesIncreased permeability, smooth muscle contraction and increased glands secretion, which produces various clinical symptoms and signs.Type IV surreal reaction is the main cause of chronic allergic conjunctivitis. After the allergenic body accepts allergens, it stimulates T cells to transform allergenic lymphocytes, causing lymphocytes and monocyte-macrophagesReaction of sexual inflammation.
Traditional Chinese medicine believes that the pathogenesis of the disease is mostly due to lung health, wind and evil, or hepatobiliary deficiency heat, heart and spleen accumulation of heat, compound sense of wind, or because of blood deficiency and wind, which cause itching and unbearablePerformance.
How to prevent allergic conjunctivitis
Like all other allergic diseases, avoiding contact with allergens is the key to prevention.To prevent allergic conjunctivitis, we should do the following:
1.Outdoor activities reasonably.Avoid staying in the wild for a long time in the season of the spread of pollen; special attention should be paid to the eyes in the case of haze weather and sand dust, so as not to enter the eyes in the eyes.
2. Improve the living environment.Home supplies are washed and replaced diligently or mite removal insects.
3. Pay attention to personal hygiene and eye hygiene. Wash your hands and wash your face frequently. Do not rub your eyes with dirty handkerchiefs and dirty hands. Wear masks and goggles in a well -shaped environment.
4. Try to avoid using eye cosmetics such as mascara and eye shadow. It is best not to wear contact lenses.
5. Pay attention to drug allergies, such as eye drops may cause allergic reactions.
Therapeutic drugs for allergic conjunctivitis
For unfortunate "Zhongzhao", the drug intervention of allergic conjunctivitis is mainly based on the eyes of the eyes with anti -allergic eye drops.
Aramine drugs are commonly used medicines for treating allergic conjunctivitis, such as ricacinic acid Yistein’s eye fluid commonly used clinically.
2. Hydocyte stabilizer
The main drugs are sodium glycate, Lotusamine, etc.The use of hypertrophic stabilizers is effective before the large cells are removed, and it is invalid for the symptoms caused by the release of allergens that have been released.
3. Double -effect anti -allergic drugs
It is actually a composite drug with hypertrophic cell stabilizers. It not only has the effect of inhibiting the combination of histamine and target cell receptor, but also to prevent the effect of large cells from large cells.Cooperate with the two, complementary advantages.Such drugs include octal hydrochloric acid and nitrogen Deting.
4. Non -steroidal anti -inflammatory drugs
Drugs are commonly used in drugs, sodium cylindrical, and Praranpen.These drugs do not have the risk of increasing intraocular pressure, but there are certain symptoms of eye stimulation, and the risk of corneal erosion has been used for a long time.
5. Glucocortic hormone drug
Glycidal hormone drugs have powerful anti -inflammatory and anti -allergic effects, and often treat more serious and chronic allergic conjunctivitis.The local parts are fluoromilon, chlorine -daolin, Dianbi special, and acetic acid Domatomyona.However, long -term application of hormone drugs in the eye can induce adverse reactions such as high eye pressure, cataract, and concurrent infection.
Immunomantic regulators can change the normal immune pathway. For severe allergic conjunctivitis, cyclopyphus and other optional drugs are available.
