Allergic conjunctivitis is a reaction to exposure to allergens such as pollen from grasses and trees, smoke, dust or chemicals. It is characterized by redness, itching and swelling of the clear tissue covering the white of the eye (conjunctiva) and watery discharge.
The treatment of allergic conjunctivitis is variable, depending on the severity. It may include removing the allergen if possible, cool compresses for the swelling, anti-allergy eye drops, and/or anti-allergy oral medications. Severe allergic conjunctivitis may warrant consultation with an allergist and possible desensitization.
