UVEAL TRACT Main vascular compartment of the eye Uvea was derived from the Latin word uva.

Uveal tract anatomy. It is sandwiched between the corneoscleral shell externally and the retina internally It is relatively firmly adherent to the sclera at the scleral spur anteriorly and at the optic nerve posteriorly and in between at the exit points of the four vortex veins. It sits between the retina innermost layer and sclera. Major circle of the iris.

It consists of 3 parts. It is traditionally split up into three anatomical portions. Uva grape also called the uveal layer uveal coat uveal tract or vascular tunic is the pigmented middle of the three concentric layers that make up an eyeThe name is possibly a reference to its almost black colour wrinkled appearance and grape-like size and shape when stripped intact from a cadaveric eye.

The uveal tract is the densely pigmented vascular tunic of the eye. Uvea is the middle vascular coat of the eyeball. Grape Located between the sclera and the retina 3 parts Iris Ciliary body Choroid.

It consists of the iris ciliary body and choroid lying in continuity with one another. It is usually pigmented and is the vascular layer of the globe. The uveal tract is a pigmented vascular layer lying between the retina and sclera.

Uveas also called the uveal layer or vascular tunic is the middle of the three layers that make up the eye. The uveal tract consists of the following structures. Urinary tract the organs and passageways concerned in the production and excretion of urine from the kidneys to the urinary meatus.

1Regulates light entry 2Give distinctive eye colour. 1 The uveal tract is firmly adherent to the scleral spur anteriorly the optic disc posteriorly and at the exit points of the four vortex veins in between. The uveal tract is the middle layer of the eye divided into the anterior uvea iris ciliary body and posterior uvea choroid.

Extends from the optic nerve posteriorly to the ciliary body anteriorly. Choroid is a posterior part of uveal tract which extends from optic disc to ora serrata. From anterior to posterior the uvea or uveal tract can be divided into three parts- Iris Ciliary body and choroid.

Choroid a thin soft brown coat lining the inner surface of the sclera. It consists of the iris ciliary body and choroid lying in continuity with one another. Uvea or uveal tract the middle layer of tissue surrounding the eye that consists of the iris ciliary body and choroid.

The uveal tract lies between the sclera and retina. Iris Thin pigmented contractile circular structure analogous to the diaphragm of a camera Anterior extension of uveal tract Extends from iris root to iris margin that forms the pupil Central aperture is called pupil 3-4mm Lies on anterior lens surface surrounded by aqueous humour Posteriorly Central portion of iris is in contact with lens which give characteristic conical configuration Functions. Thickest at the posterior pole about 022 mm and gradually thins anteriorly about 01 mm.

Respiratory tract respiratory system. It contributes blood supply to the retina. The uvea provides nutrients to the retina and lens as well as assists in refractive function of the eye.

The uvea also called the uveal layer uveal coat uveal tract vascular tunic or vascular layer is the pigmented middle of the three concentric layers that make up an eye. It consists of blood vessels from ophthalmic artery and supplies the outer part of retina. The uveal tract makes up the middle layer of the globe and consists of the iris ciliary body and choroid.

The uveal tract consists of a pigmented highly vascular loose fibrous tissue that can be divided into three anatomical regions. It is the pigmented layer and its main function is of nutrition and gas exchange. Apart from the specialized muscular structures of the iris and ciliary body the uveal tract is concerned with nutrition of the eye through the secretion of.

The anterior segment is separated from the posterior segment by the lens. Uveal tract is a middle highly vascular layer of eye ball. The uveal tract is a pigmented vascular layer lying between the retina and sclera.

Anterior three fourths ie the stroma. The name uvea has originated from the Latin word grape. Uveitis can affect people at any age but onset usually occurs in the third and fourth decades of life.

The iris is the visible coloured layer seen within the eye. THE UVEA RUTH ANTOLIN MD DOH EYE CENTER. The anterior uvea includes the iris and ciliary body while the choroid comprises the posterior uveal tract.

EMBRYOLOGY OF THE UVEAL TRACT has two components. See also urinary system. The blood supply.

The uvea is sandwiched between an outer layer sclera and an inner layer retina. The short posterior ciliary arteries enter the eyeball with the optic nerve and supply the choroid. Iris the ciliary body and the choroid.

For the Pacific island see Wallis Island. Iris Ciliary body Choroid. Uveal tract the vascular tunic of the eye comprising the choroid ciliary body and iris.
