Definition: An inflammation of the conjunctiva of the eye resulting from exposure to an allergen. Symptoms include redness, swelling, itching and increased tearing of the eyes. These symptoms are produced by histamines, which are released by certain cells in the eye in an effort to protect the eye from the allergen.
Treatment includes avoidance of the allergen causing the reaction, which may include pollen, animal dander, perfumes and cosmetics, some skin medicines, air pollution and smoke. Treatment may also involve taking certain medications including antihistamines, decongestants, and medicated eye drops.
Allergic conjunctivitis is also known as pink eye. Unlike pink eye, which is caused by a virus or bacteria, allergic conjunctivitis is not contagious.
Also Known As: Pink Eye
