What is allergic conjunctivitis?

Allergic conjunctivitis, also known as allergic reaction conjunctivitis, is a hypersensitivity reaction of the conjunctiva to external allergens. It is primarily caused by various factors including genetic predisposition, allergens in the living environment (such as dust mites, pollen, pet dander, etc.), individual allergic constitution, and seasonal allergens. Symptoms of allergic conjunctivitis include increased secretions, conjunctival edema, conjunctival hyperemia, and subconjunctival hemorrhage. Common clinical manifestations are itchy eyes, foreign body sensation, photophobia, and other discomforts. Treatment methods for allergic conjunctivitis include pharmacological therapy, surgical therapy, and timely removal from the allergen. Additionally, attention should be paid to eye hygiene and avoiding excessive eye strain to alleviate symptoms and prevent recurrence. For specific conditions and treatment plans, please consult a professional physician.
