The uvea, also known as the vascular tunic, is a pigmented layer that provides vital nourishment to the eye's delicate tissues. Its primary functions include regulating the amount of light entering the eye and supplying oxygen and nutrients to the retina.

2024年8月6日 · The uvea is the middle layer of your eye’s outer wall. It has several vital jobs, including circulating blood to your retinas, focusing your eyes and more.

The uvea (/ ˈjuːviə /; [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.

葡萄膜（Uvea）又称眼球血管膜（vascular tunic）、色素膜，是眼球壁的中间层（外层为纤维膜，内层为神经膜），此膜像紫黑色、又圆又软的葡萄而得名，由疏松结缔组织构成，富含血管和色素，故也叫血管膜或色素膜。

2021年4月1日 · Uvea is the middle vascular coat of the eyeball. From anterior to posterior, the uvea or uveal tract can be divided into three parts- Iris, Ciliary body, and choroid. The name “uvea” has originated from the Latin word grape.

2023年11月3日 · 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.

2014年1月1日 · The uvea can be involved in inflammatory processes of varying degrees of severity, and they can be localised (diffuse or nodular) as well as part of systemic conditions. Trauma to the uveal tract can be either surgical or nonsurgical.
