CHOROIDAL ARTERY Meaning and
Definition
-
The choroidal artery is a blood vessel that supplies oxygenated blood to the choroid, a pigmented vascular layer located within the eye. This artery is a branch of the ophthalmic artery, which is itself a branch of the internal carotid artery. The choroidal artery runs along with the optic nerve and passes through the optic canal to reach the choroid layer.
The main function of the choroidal artery is to provide a rich blood supply to the choroid layer, ensuring its proper functioning. The choroid, located between the retina and the sclera, is responsible for the nutrition of the outer layers of the retina. It supplies oxygen and nutrients to the photoreceptor cells, which are crucial for visual perception.
The choroidal artery is also involved in the regulation of intraocular pressure and heat exchange within the eye. By supplying blood to the choroid, it helps maintain the appropriate pressure within the eye and prevents damage to the delicate structures located in the posterior segment of the eye.
Disruption or blockage of the choroidal artery can lead to various eye conditions, including choroidal ischemia, which is a deficiency of blood supply to the choroid. This can cause visual disturbances, retinal detachment, or loss of vision. Therefore, the choroidal artery plays a vital role in maintaining the health and function of the choroid and overall eye health.

Etymology of CHOROIDAL ARTERY
The word "choroidal" derives from the Latin "choroideus", which means "relating to the choroid". "Choroid" comes from the Greek word "khoroeidēs", which means "like a chorion". The term "chorion" refers to the membrane that surrounds the fetus in the womb.
The word "artery" has a different etymology and comes from the Latin word "arteria", which means "windpipe" or "artery". The Latin term originates from the Greek word "artēria", which initially referred to the air tube leading to the lungs. Later, it began to be used to describe the blood vessels that deliver oxygenated blood from the heart to various parts of the body.
