Despite prior reports of successful dinitrochlorobenzene use for tropical immunotherapy, its failure in our patient, and the first documented attempt to employ Rhus oleoresin (poison ivy/oak) extract for topical conjunctival immunotherapy is reported. The role of topical immunotherapy in treating recurrent conjunctival papillomas is discussed.
