Allergic conjunctivitis, unlike many ocular conditions, is rarely asso
ciated with permanent visual impairment. It is, however, a common and
extremely uncomfortable problem for those who are affected. Because pa
tients with allergic conjunctivitis may be seen by the allergist and t
he ophthalmologist, it is important for both to recognize the hallmark
s of allergic conjunctivitis and to understand the different therapeut
ic alternatives for the management of this condition.
