The corneal posterior wall, the surface of trabecular meshwork,anterior chamber angle and iris are covered with different thickness of non-keratinized squamous cells (black arrows; HE,×40).

Figure 2 The structure of invading epithelial layer under HE staining
(A) The invading epithelial layer is thick the root of the iris to the angle of the anterior chamber, reaching over 10 layers at the thickest point (black arrow), and gradually becoming thinner to a single layer (white arrow; HE, ×200); (B) corneal endothelial cells between Descemet’s membrane and the invading epithelium are replaced by homogeneous, unstructured tissues with pigmentation(HE, ×400).
