From: A unique pre-endothelial layer at the posterior peripheral cornea: ultrastructural study
Light and electron micrographs of the peripheral posterior cornea; (A) Light micrograph of a part of the peripheral cornea showing the stroma, Descemet’s membrane (DM), endothelium (EN), and the Descemet’s membrane endpoint (DME). (B) Part of the peripheral cornea at a distance 105 µm from the DME, showing the DME, EN, pre-endothelial layer (PENL), DM, and pre-DM layer (PDL); (C) Part of the peripheral cornea at a distance of 167 µm from the DME, showing the EN, PENL, DM, PDL, and split basement membrane containing a large cell. (D) Part of the posterior cornea at the distance of 452 µm from the DME, showing the thinning of the PENL between DM and the EN. (E) Part of the posterior cornea at 761.6 nm from the DME, showing the stroma, DM, and EN. No PENL and PDL are observed. BM basement membrane, DM Descemet’s membrane, DME Descemet’s membrane endpoint, EN endothelium, KR keratocyte, PDL pre-Descemet’s membrane layer, PENL pre-endothelial layer, S stroma.
