• What's the difference between allergic and infectious conjunctivitis?


    Question:

    My son has allergies and often rubs his eyes and they do get a little red. How do I know when it's just his allergies and when I should have it checked for pink eye?


    Answer:

    Both pink eye and allergic conjunctivitis can make the eye(s) turn red. The hallmark of allergic conjunctivitis is itching. Patients with allergic conjunctivitis may also have a mild watery or stringy discharge. Pink eye is a term used to describe conjunctivitis that is due to an infection. Itching is not typically a prominent feature of pink eye and the patient usually has a more prominent discharge from the eye.
