Choroid veins

Choroid Veins

Choroid veins as seen in Gray's Anatomy

The Choroid veins are a group of veins located in the choroid, a part of the eye that contains blood vessels and connective tissue. These veins play a crucial role in the vascular supply of the eye, particularly the outer retina and the choroid itself.

Structure[edit | edit source]

The choroid veins are part of the choroidal circulation, which is primarily responsible for supplying the outer layers of the retina with oxygen and nutrients. These veins are located in the choroid layer, which is sandwiched between the retina and the sclera.

Function[edit | edit source]

The primary function of the choroid veins is to drain deoxygenated blood from the choroid and the outer retina. They also play a role in thermoregulation of the eye, helping to dissipate heat generated by the high metabolic activity of the retina.

Clinical significance[edit | edit source]

Abnormalities in the choroid veins can lead to various eye conditions. For instance, blockage of these veins can result in choroidal effusion or choroidal detachment. Moreover, changes in the choroid veins can be indicative of diseases such as age-related macular degeneration and central serous chorioretinopathy.
