d: Lamellae, the fibers of which are cut longitudinally. e: Transition to the sclera, with more distinct fibrillation, and surmounted by a thicker epithelium. f: Small blood vessels cut across near the margin of the cornea. Corneal cross-section imaged by an SD-OCT. The human cornea has five layers (possibly six, if the Dua's layer is included ...
Iris Gonioscopy of the anterior chamber angle Anterior chamber angle cross-section imaged by an SD-OCT. The trabecular meshwork is an area of tissue in the eye located around the base of the cornea , near the ciliary body , and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the ...
Corneal cross-linking (CXL) with riboflavin (vitamin B 2) and UV-A light is a surgical treatment for corneal ectasia such as keratoconus, PMD, and post-LASIK ectasia. It is used in an attempt to make the cornea stronger. According to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [2]
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 ...
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 eye and support the deeper structures.
The anterior chamber angle is a part of the eye located between the cornea and iris which contains the trabecular meshwork. The size of this angle is an important determinant of the rate aqueous humour flows out of the eye, and thus, the intraocular pressure. The anterior chamber angle is the structure which determines the anterior chamber depth.

The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina. [1] It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.
