From: Corneal epithelial ingrowth after perforating corneal injury: a case report
Light and transmission electron microscopy of the host cornea (left eye) a. Corneal perforation with epithelial plug (anterior 2/3 of the cornea) containing pigmented cells. EP = epithelial plug. DM = Descemet´s membrane. PC = pigmented cells. Measured resolution of images is not known. Detectors are not known, filters were not used. b. degenerative epithelial cell remains (black arrow) and strongly pigmented cells resembling pigmented cells from the irisstroma (small melanin granules) and iris pigment epithelium (large melanin granules) in the lower wound gap (posterior 1/3 of the cornea). PC = pigmented cells. DM = Descemet´s membrane. Measured resolution of images is not known. Detectors are not known, filters were not used. c. Extension into the wound gap of the posterior collagenous layer (arrow) on the ruptured Descemet´s membrane, and immigrating endothelial cells (star). PC = pigmented cells. DM = Descemet´s membrane. Measured resolution of images is not known
