Conjunctival biopsies from patients with cicatricial pemphigoid affecting the conjunctiva and patients undergoing cataract surgery (normal conjunctiva) were snap-frozen, cryostat sectioned and incubated with fluorescein-conjugated lectins; peanut agglutinin (PNA), Helix pomatia agglutinin (HPA), soybean agglutinin (SBA), wheat germ agglutinin (WGA) and succinylated wheat germ agglutinin (S-WGA). Controls consisted of preincubating the lectins with the appropriate blocking sugars before applying the lectins to the sections. PNA and HPA stained the mucus granules contained in the conjunctival goblet cells but did not stain mucus or glycocalyx at the ocular surface distal to the goblet cells. Native WGA and S-WGA had high affinities for conjunctival goblet cells and the apical epithelial cell layers. Native WGA stained mucus and glycocalyx at the ocular surface. This staining of the ocular surface by WGA was confirmed at the transmission electron microscopic level using WGA conjugated to ferritin. Cicatricial pemphigoid patients in this study had reduced numbers of goblet cells; however, those goblet cells which were observed in cicatricial pemphigoid conjunctiva stained positively with HPA, PNA, WGA, and SWGA as did goblet cells in normal conjunctiva.
