Abstract

The cornea is dome-shaped, avascular, transparent and important in allowing the refracted light rays onto the retina. It helps in viewing the images or objects. When viewed through the microscope the cornea is comprised of five distinct layers. The corneal nutrition is derived from glucose diffusing from the aqueous humor and oxygen from the tear film. And the corneal sensation is carried through the afferent limb of the long ciliary nerves. The corneal development is the last in the series of inductive events in the formation of the eye. It is induced by the lens and the optic cup. The chapter discusses in detail about the histology of the cornea, and an overview on the development of the eye and cornea. The development of the corneal embryology has been explained with images in the chapter.
