The choriocapillary plate (choriocapillary membrane, choriocapillary layer, lamina choriocapillaris) is one of the layers of the choroid, which consists of small capillaries that provide blood supply to the retina and other eye tissues. The choriocapillary plate is located between the inner and outer layers of the eye and forms a vascular system that supplies the retina and other eye tissues with blood.
Choriocapillary plates are 20 to 30 micrometers thick and consist of many thin capillaries arranged parallel to each other. Capillaries have a diameter of about 3 micrometers, and their walls are composed of endothelial cells and a basement membrane.
The functions of the choriocapillaris plate include providing nutrition and oxygen to the tissues of the eye, as well as removing waste products from the retina. In addition, choriocapillaris are involved in regulating pressure inside the eyeball and protect the retina from damage.
Disorders of the choriocapillaris plates can lead to various eye diseases such as retinal detachment, diabetic retinopathy, glaucoma and others. Therefore, the diagnosis and treatment of choriocapillaris diseases are important aspects of ophthalmic practice.
Overall, the choriocapillaris plate plays an important role in the functioning of the eye and maintaining its health. Its violations can lead to serious illnesses, so it is important to monitor its condition and take preventive measures to prevent the development of pathologies.
