The corneal endothelium consists of a single layer of flat, hexagonal cells covering the posterior surface of the cornea. It has prominent functions in the maintenance of corneal integrity and transparency. These cells produce Descemet's membrane, dehydrate the corneal stroma, have a barrier function against the aqueous humour and possess active glucose transport mechanisms. Cell density, as well as variation in size and morphology, can be examined by specular microscopy. Pump function and permeability are determined by pachymetry and fluorophotometry. These methods permit early diagnosis of any damage of the corneal endothelium.
角膜内皮由覆盖在角膜后表面的单层扁平六边形细胞组成。它在维持角膜完整性和透明度方面具有重要功能。这些细胞产生Descemet膜，使角膜基质脱水，对房水具有屏障功能，并拥有活跃的葡萄糖转运机制。细胞密度以及大小和形态的变化可通过镜面显微镜检查。泵功能和通透性通过测厚法和荧光光度法测定。这些方法有助于早期诊断角膜内皮的任何损伤。
