Uvea

Index Uvea

The uvea (/ˈjuːvɪə/) (Lat. uva, grape), 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. The name is possibly a reference to its reddish-blue or almost black colour, wrinkled appearance and grape-like size and shape when stripped intact from a cadaveric eye. Its use as a technical term in anatomy and ophthalmology is relatively modern. [1]

Accommodation reflex

The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape and pupil size (accommodation).

Antigen

In immunology, an antigen is a molecule capable of inducing an immune response (to produce an antibody) in the host organism.

Autonomic nervous system

The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs.

Chorioretinitis

Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye.

Choroid

The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye, containing connective tissues, and lying between the retina and the sclera.

Ciliary body

The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor.

New!!: Uvea and Ciliary body · See more »

Ciliary processes

The ciliary processes are formed by the inward folding of the various layers of the choroid, i.e., the choroid proper and the lamina basalis, and are received between corresponding foldings of the suspensory ligament of the lens.

Human eye

The human eye is an organ which reacts to light and pressure.

Iris (anatomy)

In humans and most mammals and birds, the iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina.

Latin

Latin (Latin: lingua latīna) is a classical language belonging to the Italic branch of the Indo-European languages.

Ophthalmology

Ophthalmology is a branch of medicine and surgery (both methods are used) that deals with the anatomy, physiology and diseases of the eyeball and orbit.

Parasympathetic nervous system

The parasympathetic nervous system (PSNS) is one of the two divisions of the autonomic nervous system (a division of the peripheral nervous system (PNS)), the other being the sympathetic nervous system.

Pupil

The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina.

Sympathetic nervous system

The sympathetic nervous system (SNS) is one of the two main divisions of the autonomic nervous system, the other being the parasympathetic nervous system.

Sympathetic ophthalmia

Sympathetic ophthalmia (SO) or Sympathetic uveitis is a bilateral diffuse granulomatous uveitis (a kind of inflammation) of both eyes following trauma to one eye.

Uveal melanoma

Uveal melanoma is a cancer (melanoma) of the eye involving the iris, ciliary body, or choroid (collectively referred to as the uvea).

Uveitis

Uveitis is the inflammation of the uvea, the pigmented layer that lies between the inner retina and the outer fibrous layer composed of the sclera and cornea.
