2024年8月6日 · Your uvea is a three-part structure that surrounds most of your eye. The three parts of it all play a vital role in eye function. They support surrounding tissues, help control key eye functions and much more. Many conditions can affect the parts of the uvea, but there are also many things you can do to protect the health of this key layer.

The uvea is the vascular middle layer of the eye. It is traditionally divided into three areas, from front to back: The prime functions of the uveal tract as a unit are:

2023年5月3日 · The uvea (plural: uveas), also called the uveal layer or vascular tunic is the middle of the three layers that make up the eye. It is the pigmented layer and its main function is nutrition and gas exchange. It sits between the retina (innermost layer) and sclera. It is traditionally split up into three anatomical portions: iris (anteriorly)

2016年3月28日 · It is made up of the ciliary body, choroid, and iris. Read an overview of general eye anatomy to learn how the parts of the eye work together. All content on the Academy’s website is protected by copyright law and the Terms of Service.

The uvea consists of structures of the eye beneath the white of the eye (sclera). It has three parts: (1) the iris, which is the colored part of the eye; (2) the ciliary body, which is the structure in the eye that secretes the transparent liquid within the front of the eye; and (3) the choroid, which is the layer of blood vessels between the ...

Normal iris and ciliary body. Uveal tract consists of the iris, ciliary body, and choroid. It is embryologically derived from neuroectodermand neural crest. Firm attachments exist at 3 sites: Low magnification view of normal iris. Higher magnification view of normal iris. The iris separates the anterior segment into anterior +posterior chambers.

The uvea is the layer of the eye that’s between the retina and sclera and is the main blood supply for many ocular structures. It is composed of the iris, ciliary body, and choroid. This chapter covers the following diseases affecting the uvea: Posterior uveitis; Toxoplasmosis; Ocular sarcoidosis; Choroidal nevus; Choroidal melanoma

The uvea, or uveal tract, is the vascular tunic of the globe. It is divided into three portions: the iris, ciliary body, and choroid. The iris and ciliary body form the anterior uvea, and the choroid may be termed posterior uvea. The uveal tract contains virtually no resident lymphoid tissue and lacks true lymphatic vessels.

The uvea is the middle layer of the eye. It lies beneath the white part of the eye (the sclera). It is made of the iris, ciliary body, and choroid. These structures control many eye functions, including adjusting to different levels of light or distances of objects. Inflammation of one or more of these structures is called uveitis.
