(a) The basal membrane surrounding the necrotizing regions displays abundant Langerhans cells aggregation. (b) Three months after the operation, confocal microscopy indicated that the number of immunocytes had clearly decreased. (c) Normal superficial corneal epithelium cells can be seen in the negative control cornea. (d) 12 months after conjunctival flap transplantation, the conjunctival epithelium cells are replaced by ancipital corneal cells with an epithelial-like appearance, with neovascularization and the proliferation of fibrous connective tissue.
