Conjunctivitis is the inflammation of the conjunctiva tissue that covers most of the outer white part of eye and the inner surface of the eyelids. This infection within the eyelid may result from bacteria, viruses or allergens. It is called allergic conjunctivitis if the inflammation occurred due as a result of an allergic reaction. Allergic conjunctivitis is one of most common allergic conditions worldwide. Itchy eyes is the most typical symptom and this is important in distinguishing allergic conjunctivitis from other ocular conditions. Seasonal and perennial allergic conjunctivitis is the most common forms. It is frequently present with other systemic allergic disorders, mainly with allergic rhinitis. The frequency of its association with allergic rhinitis is 50 – 75%.
