Schlemms canal, also known as canal of Schlemm, is a circular channel in the eye that collects aqueous humor from the anterior chamber and delivers it into the bloodstream . ... This is an area of tissue located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humour from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea). ... The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber, providing most of an eyes optical power [1]. Together with the lens, the cornea refracts light and, as a result, helps the eye to focus. ... The corneal epithelium (epithelium corneæ anterior layer) covers the front of the cornea and consists of several layers of cells. ... The Bowmans membrane is a smooth layer in the eye. ... The substantia propria (or stroma of cornea) is fibrous, tough, unyielding, and perfectly transparent. ... Descemets membrane is the basement membrane that lies between the corneal proper substance, also called stroma, and the endothelial layer of the cornea. ... Corneal endothelium is the inner most layer of the cornea, the corneal endothelium is actually a monolayer of squamate epithelial cells lining the anterior chamber of the eye. ... For the Pacific island, see Wallis Island. ... The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye lying between the retina and the sclera. ... The ciliary processes are formed by the inward folding of the various layers of the choroid, i. ... Bruchs membrane is the innermost layer of the choroid. ... The human iris The iris is the green/grey/brown area. ... The human eye The pupil is the central transparent area (showing as black). ... Schematic diagram of the human eye The ciliary body is the part of the eye containing the ciliary muscle and ciliary processes. ... Human eye cross-sectional view. ...

The anterior chamber if the fluid-filled space inside the eye between the iris and the corneas innermost surface, the endothelium . ... The aqueous humour is a a thick watery substance that is located in the eye. ... The posterior chamber is a narrow chink behind the peripheral part of the iris, and in front of the suspensory ligament of the lens and the ciliary processes. ... Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens. ... The posterior segment is the back two-thirds of the eye that includes the anterior hyaloid membrane and all structures behind it: the vitreous humor, retina, choroid, and optic nerve. ... Vitreous humour is the clear aqueous solution that fills the space between the lens and the retina of the vertebrate eyeball. ... It has been suggested that this article or section be merged with Zonule of Zinn. ... The zonule of Zinn is a ring of fibrous strands connecting the ciliary body with the crystalline lens of the eye. ...
