The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. [1] [2] In humans, the refractive power of the cornea is approximately 43 dioptres. [3]
The anterior segment or anterior cavity [1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [2] [3] Within the anterior segment are two fluid-filled spaces: the anterior chamber between the posterior surface of the cornea (i.e. the corneal endothelium) and the ...
Schematic diagram of the human eye. It shows a horizontal section through the right eye. The eye is made up of three coats, or layers, enclosing various anatomical structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera, which provide shape to the

In the leftmost photo, the pupil is relatively posterior (set back), indicating an EZ ratio of < 0.5 and an anterior chamber deeper than 2.5 mm. In the middle photo, the pupil is midway between the sclera posteriorly and the cornea anteriorly, indicating an EZ ratio of 0.5, and a medium chamber depth of about 2.5 mm.
The corneal limbus is the border between the cornea and the sclera. [1] It is highly vascularised. [1] Its stratified squamous epithelium is continuous with the epithelium covering the cornea. [2] The corneal limbus contains radially-oriented fibrovascular ridges known as the palisades of Vogt that contain limbal stem cells.
The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [ 1 ]
