Uveal Tract (Uvea, Uveal Tract)

The uveal tract is the choroid of the eyeball, which is located under the sclera and contains the iris, ciliary body, ciliary body, as well as the choroid itself. The uveal tract is an important organ not only for vision, but also for regulating blood supply to the eyeball.

The choroid is a thin layer of tissue that surrounds the lens and retina. It consists of capillaries that provide nutrition and oxygen saturation of these structures. The choroid also plays an important role in regulating intraocular pressure and protecting against infections.

The ciliary body is a structure that is located at the back of the eye and is responsible for focusing images on the retina. It is made up of muscle fibers that can contract and relax, changing the shape of the lens.

The iris is the anterior part of the choroid of the eye, which has a colored membrane made of melanin and carotene pigments. It regulates the amount of light entering the eye and protects it from ultraviolet rays.

The uveal tract also contains the ciliary bodies, which are located at the back of the eyeball and are responsible for the production of intraocular fluid. This liquid is necessary to moisturize the eyeball and protect it from damage.

Overall, the uveal tract plays an important role in eye function and health. Dysfunction of this organ can lead to various diseases, such as glaucoma, cataracts and others. Therefore, it is important to monitor your eye health and undergo regular medical examinations.

Uveal tract - choroid of the eye. It is located under the sclera and includes the choroid itself, the ciliary body and the iris. The uveal tract is an important organ that provides nutrition to the eye and protects it from external influences.

The choroid of the eye consists of capillaries that provide nutrition to the eye tissues, as well as pigment cells that protect the eyes from excess light. The ciliary body is responsible for the accommodation of the eye, that is, the ability of the eye to focus on objects at different distances. The iris is the eye's protective mechanism; it regulates the amount of light entering the eye and protects it from damage.

The uveal tract also plays an important role in the exchange of substances between the blood and the tissues of the eye. It ensures the supply of nutrients and the removal of metabolic products. In addition, it is involved in the regulation of intraocular pressure, which is necessary for the normal functioning of the eye.

Injuries, tumors and other diseases can lead to disruption of the uveal tract. This can lead to various visual disturbances, such as decreased visual acuity, spots or distortions in the field of view. Therefore, it is important to monitor the condition of the uveal tract and consult a doctor if symptoms of its disorder appear.

The uveal tract is the choroid of the eye and is located under the sclera (the outer layer of the eye). It consists of the uvea itself, the ciliary body and the iris. Uvea form the inner layer of the choroid and consist of endothelial cells. It nourishes the retina, posterior chamber and lens area.

The choroid has many important functions, including regulating intraocular pressure (IOP), maintaining ocular homeostasis and blood supply, and participating in image formation. Inside the walls of blood vessels there are smooth muscles that regulate
