Vorticose veins

Vorticose veins are a group of veins that drain the choroid in the eye. They are also known as the vortex veins or venae vorticosae.

Etymology

The term vorticose is derived from the Latin word vortex, which means whirlpool. This is in reference to the spiraling pattern these veins form in the eye.

Anatomy

Vorticose veins are located in the uveal tract, specifically in the choroid layer. They are responsible for draining the majority of the blood from the choroid, ciliary body, and iris of the eye. There are typically four to six vorticose veins in each eye, and they exit the eye through the sclera, the white outer layer of the eye.

Function

The primary function of the vorticose veins is to drain deoxygenated blood from the choroid and other parts of the uveal tract. This is crucial for maintaining the health and function of the eye, as it ensures that tissues are properly oxygenated and waste products are removed.

Clinical significance

Abnormalities or damage to the vorticose veins can lead to a variety of eye conditions. For example, blockage of these veins can cause choroidal effusion, a condition characterized by fluid accumulation in the choroid. This can lead to vision loss if not treated promptly.
