Schlemms canal is not a rigid structure although it does contain septa which provide some support.

Anatomy of the eye canal of schlemm. Canal of schlemm 12. In normal n 3 and POAG n 3 eye pairs one eye was perfused at 10 mm Hg while the fellow eye was perfused at 20 mm Hg for 2 hours. Canal of Schlemm The watery fluid called aqueous humor that circulates from the posterior chamber through the pupil and into the anterior chamber leaves the anterior chamber through veins and the canal of Schlemm a special drainage canal in the anterior chamber s wall.

From this plexus the blood containing the aqueous humour passes into more superficial vessels. The function of Schlemms canal is to collect the aqueous humor from the anterior chamber of the eyeball and deliver it to the veins of the eyeball. It finally leaves the Read More.

To the anatomy of this period belongs the description of the spaces of Fontana as also the discovery by Demours of the canal of Petit so named by him the Zonula of Zinn commemorates the name of an observer who also contributed studies on the blood-vessels around the entry of the optic nerve circulus arteriosus of Zinn and on the action of. It is named after Friedrich Schlemm 17951858 a German anatomist. The majority of fluid draining out of the eye is via the trabecular meshwork then through a structure called Schlemms canal into collector channels then to veins and eventually back into bodys circulatory system.

The Canal of Schlemm is a canal located in the eye also known as the scleral venous sinus or Schlemms canal. Canal of schlemm 12. Trabecular meshwork and Canal of Schlemm slide EYE-2 Trabecular meshwork and Canal of Schlemm View Image at the limbus The sclera is the opaque part of the outermost coat or tunic of the eye the tunica externa that covers about 56 of the eye.

It is the most posterior part of the vascular coat sheet of the eye and is located between the sclera and the retina. This channel the canal of Schlemm encircles the cornea and connects by small connector channels to the blood vessels buried in the sclera and forming the intrascleral plexus or network. A spongy trabecular meshwork fills the angle between cornea and iris Photo B and contains the canal of Schlemm a circular lymphatic-like vessel.

In this image you will find conjunctiva ora serrata ciliary body aqueous iris anterior chamber cornea pupil lens the posterior chamber in it. Canal of Schlemm is not a rigid tube and at higher intraocular pressure it often collapses. Central retinal vein 13.

Eye anatomy this diagram details the different parts and structures of the human eye showing. A thin membrane that consists largely of blood vessels that nourishes the outer part of the retina. On the scleral side of Schlemms canal the endothelium is much smoother and is intermittently perforated by 25 to 35 aqueous collector channels.

The canal of Schlemm or the scleral venous sinus is a circular canal found within the posterior part of the corneoscleral junction. At high intraocular pressures the canal collapses and resistance to aqueous outflow increases. It is difficult to estimate the thickness of the choroid because of the numerous vessels.

Central retinal artery 15. The canal is essentially an endothelium-lined tube resembling that of a lymphatic vessel. Central retinal vein 13.

This image shows the different parts of the eye showing. This is a watery solution with a high nutrient component that supports the avascular cornea and lens. Interestingly he was also the first person to describe the corneal nerves.

Schlemms canal is a circular lymphatic-like vessel in the eye that collects aqueous humor from the anterior chamber and delivers it into the episcleral blood vessels via aqueous veins. To examine the anatomy of Schlemms canal SC and collector channels CCs in normal human and primary open-angle glaucoma POAG eyes under low and high perfusion pressure. As watery aqueous humor is made by the ciliary body it collects in the posterior chamber and then flows forward through the pupil into the anterior chamber Photo B.

Schlemms canal is named after a German anatomist. You may also find iris pupil cornea suspensory ligament of the lens zonule of Zinn ciliary body conjunctiva inferior rectus muscle posterior cavity vitreous chamber as well. Aqueous is continuously produced in the posterior chamber flowing forward through the pupil into the anterior chamber where it drains back into the venous circulation via the Canal of Schlemm.

It can be opened up by a pull on the scleral spur exerted by longitudinal ciliary muscle fibres. Circular in shape the canals function is to collect fluid called aqueous humor from the anterior chamber of the eye and move it to the blood and vascular system.
