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.

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
