Schlemm's canal, also known as the canal of Schlemm, and as the scleral venous sinus, 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. Canaloplasty may be used to widen it.
Here, the ASV can be located aligned with the femoral vessels at the "alignment sign". [34] Also, at the groin it can be seen at the outside of the great saphenous vein, and together with the common femoral vein (CFV) these three create an image, the so-called "Mickey Mouse sign". Some authors, inspired by this sign (presented for the first ...
Mickey Mouse sign is a medical sign resembling the head of Mickey Mouse, the Walt Disney character. Presented for the very first time at the CHIVA's Meeting, Berlin 2002 by Dr. Lurdes Cerol, [citation needed] this sign has been described as the image at the groin when a dilated accessory saphenous vein (ASV) exists: the common femoral vein (CFV) represents the head of Mickey Mouse while the ...
Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body. They also take waste and carbon dioxide away from the tissues. [2] Some tissues such as cartilage, epithelium, and the lens and cornea of the eye are not supplied with blood vessels and are termed avascular.
The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
There is autobiography here — a self-portrait of her cycling around Venice circles a vase — as well as satire. One ceramic tile features a row of library bookshelves, labelled variously ...
The central retinal vein (retinal vein) is a vein that drains the retina of the eye.It travels backwards through the centre of the optic nerve accompanied by the central retinal artery before exiting the optic nerve together with the central retinal artery to drain into either the superior ophthalmic vein or the cavernous sinus.
The ophthalmic artery (OA) is an artery of the head.It is the first branch of the internal carotid artery distal to the carotid sinus.Branches of the ophthalmic artery supply all the structures in the orbit around the eye, as well as some structures in the nose, face, and meninges.
