Corneal Endothelial Cells (CEC)

Corneal endothelial cells (CEC) have a crucial effect on the transparency of the cornea.The transparency of cornea is one of the important conditions to realize the normal physiological function of the visual organ,and anatomical morphology and physiological function of normal corneal endothelial layer is the key to maintain corneal transparency. 

The corneal endothelium is composed of a single layer of endothelial cells, which is hexagonal, compact and uniform in size. It is attached to the posterior elastic layer and is in contact with anterior chamber water.Corneal endothelial cells are the physiological barrier that separates the water from the corneal stroma by the active metabolic liquid pump.This effect is accomplished by the activity of Na + - K + - K + -ATP in corneal endothelial cells. The composite structure of the endothelial cells also plays a role in preventing moisture penetration into the cornea.
