IGHE and atopic conjunctivitis: The results obtained in VKC concur with those in the literature.Locally-produced IgE levels have been shown to be the largest contributor tothe severity of allergic conjunctivitis [16], particularly in chronicforms, and local IgE production in VKC is increased compared with controls [13, 14] although no clinical differences were observed in atopickeratoconjunctivitis (AKC) [17].
