Who was the canal of Schlemm named after?
Friedrich Schlemm
The Schlemm’s canal (SC), named after the German anatomist, Friedrich Schlemm and first identified in 1830 [1], is a unique, ring-shaped, endothelium-lined vessel that encircles the cornea [2,3] (Figure 1). Anatomically, it is situated directly against the juxtacanalicular (JCT) region of the trabecular meshwork (TM).
How big is Schlemm’s canal?

What causes blocked drainage canals in the eye?
What Causes High Pressure Inside the Eye? High pressure inside of the eye is caused by an imbalance in the production and drainage of the fluid in the front of the eye (aqueous humor). The channels that normally drain the fluid from inside the eye consequently do not function properly or are blocked.
What gets blocked in glaucoma?
Glaucoma occurs when blockage of the drainage outlets for the aqueous humor causes pressure in the eye to build up. The higher fluid pressure can damage the optic nerve. This is where the part of the nerve called the retinal ganglion enters the back of your eye.
What causes aqueous humor?
The aqueous humour is a thin, transparent fluid similar to plasma. It’s made up of 99.9% water – the other 0.1% consists of sugars, vitamins, proteins and other nutrients. This fluid nourishes the cornea and the lens, and gives the eye its shape.
What is the function of the Schlemm’s canal in the eye?
Schlemm’s canal is a circular lymphatic-like vessel in the eye. It collects aqueous humor from the anterior chamber and delivers it into the episcleral blood vessels.
Where is Schlemm’s canal in eye?
The canal of Schlemm, or the scleral venous sinus, is a circular canal found within the posterior part of the corneoscleral junction. The function of Schlemm’s canal is to collect the aqueous humor from the anterior chamber of the eyeball and deliver it to the veins of the eyeball.

What is the canal of Schlemm in the eye?
The Canal of Schlemm is a canal located in the eye, also known as the scleral venous sinus or Schlemm’s canal. Circular in shape, the canal’s function is to collect fluid called aqueous humor from the anterior chamber of the eye and move it to the blood and vascular system.
What is Canal Schlemm of the eye?
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 episcleral blood vessels via aqueous veins. It is named after Friedrich Schlemm (1795-1858), a German anatomist. The canal is essentially an endothelium-lined tube, resembling that of a lymphatic vessel.
What is canal of Schlemm?
