Figure 2. No positive reaction for thymine dimer immunohistochemistry in normal conjunctiva (A). Note the weak and inconstant positive reaction in the epithelium but not in the subepithelial layer from one case of normal conjunctiva (a, inset). Nuclear thymine dimer expression in the primary pterygium epithelium (B) and recurrent pterygium (D). Note the persistence of positive thymine dimer cells in the basal layer (C).
