Allergic conjunctivitis

Allergic conjunctivitis is a common disease of the eyes caused by allergies. In daily life, it is mainly caused by the use of eye cosmetics and the wearing of contact lenses. Some factors such as aggravated air pollution can easily lead to the occurrence of this disease. We must always have a correct understanding of allergic conjunctivitis and some reasonable medication. Allergic conjunctivitis is mainly caused by contact allergic antigens.

Therefore, in daily life, a group of people who find allergens mainly suffer from allergic conjunctivitis. Initially there is conjunctival hemorrhage and edema with sticky discharge. Nursing in daily life is also very important. If the work is not done well, then some drug treatment should be convenient.

Allergic eye disease is one of the most common ocular surface diseases, among which allergic conjunctivitis is the most common type. According to statistics, more than 5% of the world's population seeks medical treatment for allergic eye diseases, and the proportion of allergic conjunctivitis exceeds 50%. In recent years, the incidence rate has further increased due to factors such as the use of eye cosmetics, wearing contact lenses, and increased air pollution. Therefore, it is of great significance to correctly understand allergic conjunctivitis and use medication rationally. Allergic conjunctivitis is an allergic reaction of the conjunctiva caused by contact with allergic antigens, which is mainly a type I allergic reaction mediated by IgE. Anyone who is genetically or physically susceptible to specific antigens may develop allergic diseases such as immediate or delayed allergic conjunctivitis, often accompanied by allergic rhinitis, when exposed to such antigens. Seasonal allergic conjunctivitis is most common in young and middle-aged people. It has a rapid onset and occurs when exposed to allergens. Symptoms are relieved when away from allergens. The main difference between perennial and seasonal conjunctivitis is that allergic symptoms exist all year round. Contact allergic conjunctivitis has a clear history of exposure, such as exposure to drugs or cosmetics. Giant papillary conjunctivitis is often associated with a history of contact lens (corneal contact lens) wear. Vernal keratoconjunctivitis is more common in children and often occurs or worsens in spring and summer. Atopic conjunctivitis is more common in middle-aged men, and often has a history of mild allergies in the early stages. Some vernal keratoconjunctivitis and atopic conjunctivitis can cause serious corneal complications and even endanger vision.

The above is the treatment of allergic conjunctivitis. It is very critical to find the allergens in a group of people in daily life, mainly some patients with allergic conjunctivitis. Initial conjunctival hemorrhage and edema and sticky secretions can cause other types of diseases in daily life, so they must be treated in time in daily life. .
