Loss of canthal architecture and symblepharon formation in linear IgA disease. See article by Caux et al elsewhere in this issue. Figure 5. Sections of human conjunctiva stained by double immunohistochemistry with anti-tryptase and anti-chymase antibodies. MCT cells are visualized in blue. MC, cells are visualized in brown. A, Section of normal conjunctiva showing two MC, cells in the epithelium and several MC, cells in the substantia propria (original magnification x 1100). B, cell, and Section of vernal conjunctivitis showing one intact MC, cell, one intact MC, numerous free MCT, granules in the substantia propria (original magnification x 1700). E = epithelium, SP = substantia propria. See the article by lrani elsewhere in this issue.
