Spring returns to the earth, birds sing and flowers smell, and the alarm sounds in the season of high incidence of allergies. Pollen, dust mites, fungi, animal hair and other antigens in the environment are easy to cause allergic reactions, which is also the season of frequent allergic conjunctivitis. Today, Wang Yingli, chief ophthalmologist of the emergency general hospital (former coal general hospital), came to introduce to you six kinds of commonly used eye drops to deal with allergic conjunctivitis. These two kinds of allergic conjunctivitis account for 70% Allergic conjunctivitis is a high incidence rate of ocular allergic diseases. Allergic people suffer from allergic conjunctivitis more often than others. Patients with allergic rhinitis may also cause allergic conjunctivitis when rhinitis occurs. Allergic conjunctivitis is mainly divided into perennial allergic conjunctivitis, seasonal allergic conjunctivitis, spring keratoconjunctivitis, giant papillary conjunctivitis, atopic keratoconjunctivitis, etc. the first two are the most common, accounting for about 70% of all patients with allergic conjunctivitis. Does anti-inflammatory Eye Drops work? That's not right How to treat allergic conjunctivitis is the most concerned problem. How can those anti-inflammatory eye drops not work at all? Wang Yingli told you that there are six types of eye drops commonly used to treat allergic conjunctivitis: Antihistamines, the most commonly used eye drops, can competitively block histamine receptors and reduce eye itching and redness. It works quickly and can effectively reduce symptoms and signs. However, the action time is short, and it can only treat mild to moderate allergic conjunctivitis. At present, the second generation H2 receptor antagonist eye drops mainly include emestine fumarate. Mast cell stabilizer its mechanism is to stabilize mast cells and eosinophils, and inhibit the occurrence of allergic conjunctivitis by inhibiting mast cell degranulation and histamine release. This process takes three to five days to achieve the best effect. The effect is slow, but the effect is long-lasting. It is often used in combination with antihistamines and can also be used as a preventive drug in the season of high incidence of allergic conjunctivitis. Common non-ferrous glycoside sodium, pyrrolimus potassium (Yanli Shuang), etc. Antihistamines and mast cell stabilizer double effect drugs. These drugs can simultaneously antagonize histamine and stabilize mast cell membrane. They have good curative effect and comfort. They are the first choice for the treatment of allergic conjunctivitis. It is recommended to use this kind of drugs for patients in acute stage. The double effect drugs widely used in recent years are olotadine hydrochloride eye drops and azelastine eye drops. NSAIDs inhibit the production of inflammatory mediators such as prostaglandins in type I hypersensitivity by inhibiting cyclooxygenase, so as to play the role of anti-inflammatory and analgesic, and reduce conjunctival congestion and pruritus. It is suitable for some mild seasonal allergic conjunctivitis. Nonsteroidal anti-inflammatory drugs currently used in the eyes include praprofen, diclofenac sodium and bromofenac sodium eye drops. Glucocorticoids can effectively inhibit the activation of a variety of immune cells and the release of inflammatory response mediators. It is suitable for patients with severe allergic conjunctivitis and repeated delay of disease. The use time should not be too long. Attention should be paid to follow-up observation to avoid complications such as cataract, glaucoma and delayed corneal epithelial healing. Glucocorticoids used locally in the eyes include flumetasolone, dianbishu (tobramycin dexamethasone) and prednisolone acetate. Don't talk about hormone discoloration. Master the indications and use time. These drugs have a rapid effect and strong antipruritic effect. They are a good helper in clinical practice. In particular, dianbishu eye ointment has a good effect on eyelid pruritus. Artificial tears can be used as adjuvant treatment. It can dilute the allergens in the conjunctival sac, lubricate the ocular surface, and refrigerated tears can better alleviate the symptoms of patients. Commonly used preparations include sodium hyaluronate eye drops, polyvinyl alcohol eye drops, etc. The disease is self limiting and eye medicine should be moderate Allergic conjunctivitis has certain self limitation, and the medication time should not be too long, and most of the disease is related to their own physique. Regular life and rest, healthy and appropriate diet and strengthening exercise can enhance their physique and enable the body to resist allergic attacks. In addition, in daily life, we should also try to avoid or reduce exposure to allergens and improve the living environment, which will help alleviate and control the condition of allergic conjunctivitis. Patients with pollen allergy need to take protective measures as much as possible in the pollen season, such as wearing glasses and masks. Patients with dust mite allergy should do a good job in indoor cleaning and mite removal. When the air pollution is serious, patients should appropriately reduce the time of outdoor activities.
