RETINAL ARTERY Meaning and
Definition
-
The retinal artery refers to a major blood vessel that plays a crucial role in supplying oxygen and nutrients to the retina, the light-sensitive tissue lining the back part of the eye. It is one of the branches of the ophthalmic artery, a key vessel involved in nourishing various structures of the eye. The retinal artery emerges from the optic disc, also known as the optic nerve head, where the optic nerve connects to the retina.
As the retinal artery travels through the eye, it branches out into smaller vessels known as arterioles, which further supply blood to the various layers of the retina. These arterioles divide into even smaller capillaries in a complex network, ensuring adequate delivery of oxygen and nutrients to all retinal cells.
Any disruption or blockage in the retinal artery can lead to a condition called retinal artery occlusion (RAO). This is a serious medical emergency that can result in rapid vision loss or even permanent blindness if not promptly treated. RAO often occurs due to a clot or embolus that obstructs blood flow in the retinal artery.
The retinal artery, along with the retinal veins, is an important component of the circulatory system of the eye, creating a delicate balance that ensures the health and function of the retina. Regular eye examinations and early detection of any signs or symptoms related to retinal artery occlusion are crucial in preserving vision and preventing complications.

Etymology of RETINAL ARTERY
The word "retinal artery" is composed of two main components: "retinal" and "artery".
1. "Retinal": This term comes from the noun "retina", which refers to the innermost light-sensitive layer at the back of the eye. The word "retina" has its origins in the Medieval Latin term "retina" and the Latin term "rete" meaning "net".
2. "Artery": This word has its roots in the Latin term "arteria", which initially referred to an air-carrying tube or windpipe. In ancient Greek, the term "arteria" was used to describe the blood vessel that carries blood away from the heart.
Combining these two components, "retinal artery" refers to the artery that supplies blood to the retina, the innermost layer of the eye.
