title: Relation between cooling sheet effect and tear histamine concenration in allergic conjunctivitis.
abstract: Six allergic conjunctivitis patients (12 eyes) and 4 healthy volunteers (8 eyes) were investigated in terms of the effect of cooling sheets on eye itching and tear histamine concentration, before and 5 min after cooling the eyelids with cooling sheets. The severity of itching was evaluated with a five-level itching score. The combination treatment of levocabastine with cooling sheets significantly reduced eye itching, while no significant change in tear histamine concentration was observed before and after cooling sheet use. The cooling sheets are useful for reducing eye itching in the therapy of allergic conjunctivitis. The tear histamine concentration did not correlate with the antiitching effect of cooling sheets in this study.
