Schlemm's canal
(Redirected from Sinus venosus sclerae)
Schlemm's canal is a circular lymphatic-like vessel in the eye that collects aqueous humor from the anterior chamber and delivers it into the bloodstream. It was named after Friedrich Schlemm, a German anatomist who discovered it. The canal is part of the conventional outflow pathway, through which the majority of aqueous humor exits the eye.
Anatomy[edit | edit source]
Schlemm's canal is located in the scleral sulcus of the eye, between the sclera and the cornea. It is approximately 10 mm in diameter and is lined by endothelial cells. The canal is divided into smaller segments by connective tissue, creating a series of aqueous veins.
Function[edit | edit source]
The primary function of Schlemm's canal is to drain the aqueous humor from the anterior chamber of the eye into the bloodstream. This process is crucial for maintaining intraocular pressure within a normal range and preventing conditions such as glaucoma.
Clinical significance[edit | edit source]
Abnormalities in Schlemm's canal can lead to impaired drainage of aqueous humor, resulting in increased intraocular pressure and potentially leading to glaucoma. Various treatments for glaucoma aim to increase the outflow of aqueous humor through Schlemm's canal.
