Vessel of the Eye (Choroid)

The choroid is the middle layer of the eyeball. It is located between the retina (retina) and the sclera (sclera). The uvea of ​​the eye contains large blood vessels and large pigment cells that absorb excess light entering the eyes. This helps prevent vision deterioration.

The choroid of the eye consists of three main parts: the choroid itself, the ciliary body and the iris.

– The choroid is the largest part of the uvea of ​​the eye; it contains a large number of blood vessels that provide nutrition to all other layers of the eye.
– The ciliary body is a part of the choroid of the eye that connects it to the pupil. It is responsible for regulating the amount of light entering the eye.
– The iris is the outer part of the choroid of the eye. It contains pigment cells (melanocytes) that regulate the amount of light passing through the pupil.

Thus, the choroid is an important part of the eye and plays an important role in its functioning.

The membrane of the eye is choroid

The medial layer of the eyeball is the layer that is located between the retina and the sclera and contains a large number of blood vessels. This membrane is called the “choroid” and has an important function in protecting the eye from the harmful effects of light.

The choroid contains three main parts:

1. The choroid proper is the largest part of the choroid and contains many capillaries. It is responsible for transporting oxygen and nutrients to the tissues of the eye.
2. The ciliary body is the part of the choroid that contains the cilia, which are responsible for the movement of fluid inside the eye. Cilia also help regulate pressure inside the eye.
3. The iris is the front part of the uvea that contains pigment cells that absorb excess light entering the eye.

Thus, the choroid is an important part of the eye, which protects it from damage and ensures normal functioning.

The choroid choroid is the middle layer of the eyeball, located between the iris and sclerochus. It contains many blood vessels and large pigment cells that absorb excess light entering the eye to prevent loss of vision. The choroid consists of three main parts: the tunica propria, the ciliary body and the iris.

The choroid plays an important role in vision: it regulates the light flux and protects the eyes from the harmful effects of light. This is where large pigment cells are located - melanocytes, which absorb ultraviolet rays and protect the lens from their harmful effects. In addition, the choroid plays an important role in regulating intraocular pressure. As intraocular pressure increases, blood vessels dilate, blood flow increases, and pressure decreases. When it decreases, blood flow decreases, blood vessels narrow and intraocular pressure increases. Thus, the choroid affects the functioning of all other membranes and ocular structures.

Problems with the vascular membrane of the eye can lead to poor vision and other eye diseases. For example, when blood vessels dilate, red dots may appear before the eyes. With age, blood vessels can become more fragile and brittle, which can also affect vision and cause difficulties in perceiving images.
