The uvea (/ ˈ j uː v i ə /; [1] derived from Latin: uva meaning "grape"), also called the uveal layer, uveal coat, uveal tract, vascular tunic or vascular layer, is the pigmented middle layer of the three concentric layers that make up an eye, precisely between the inner retina and the outer fibrous layer composed of the sclera and cornea.
Schematic diagram of the human eye. It shows a horizontal section through the right eye. The eye is made up of three coats, or layers, enclosing various anatomical structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera, which provide shape to the eye and support the deeper structures.

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.
[1] [2] It ascends to the medial angle of the eye's orbit (the medial canthus). [2] It is embedded in the fibers of the angular head of the levator labii superioris muscle. [citation needed] It is accompanied by the angular vein. On the cheek, it distributes branches which anastomose with the infraorbital artery. [2]
The choroid, also known as the choroidea or choroid coat, is a part of the uvea, the vascular layer of the eye. It contains connective tissues , and lies between the retina and the sclera . The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm. [ 1 ] The choroid provides ...
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.
Schematic diagram of the human eye. The hyaloid canal (Cloquet's canal and Stilling's canal [1]) is a small transparent canal running through the vitreous body from the optic nerve disc (at the punctum caecum) to the lens. It is formed by an invagination of the hyaloid membrane, which encloses the vitreous body.
