LAMINA CHORIOCAPILLARIS Meaning and
Definition
-
Lamina choriocapillaris refers to a specific anatomical structure within the eye, located in the choroid layer behind the retina. It is composed of a network of tiny, thin-walled blood vessels called capillaries that provide essential nourishment to the outer layers of the retina, such as the photoreceptor cells and the retinal pigment epithelium.
This intricate network of capillaries forms a dense meshwork within the lamina choriocapillaris, allowing for efficient exchange of oxygen, nutrients, and waste products between the blood and the outer retinal layers. This process is crucial for maintaining the health and proper functioning of the retina, which is responsible for visual perception.
The lamina choriocapillaris plays a vital role in supplying oxygen and nutrients to the retina, which lacks its own direct blood supply. By being located between the retina and the choroid, it acts as an intermediary layer facilitating the necessary exchange of substances for the retinal cells' metabolic needs. Additionally, it helps regulate the temperature, metabolism, and waste removal within the retina, thus contributing to its overall homeostasis and function.
Pathological changes or diseases affecting the lamina choriocapillaris can lead to retinal dysfunction and eventual vision loss. Various conditions, such as age-related macular degeneration and chorioretinal inflammatory diseases, can disrupt the delicate balance of the lamina choriocapillaris, impairing its blood supply function and compromising the health of the retina.

Etymology of LAMINA CHORIOCAPILLARIS
The word "lamina choriocapillaris" is derived from the Latin language. Here's a breakdown of its etymology:
1. Lamina: The word "lamina" is a Latin term meaning "thin plate" or "layer". It refers to a flat, thin structure or sheet-like arrangement.
2. Chorio-: The prefix "chorio-" is also from Latin and comes from the word "chorion". In anatomy, the chorio- prefix indicates a relation to the choroid, which is the vascular layer of the eye.
3. Capillaris: The term "capillaris" comes from the Latin word "capillarius", which means "of hair" or "hair-like". It pertains to the smallest and thinnest blood vessels in the body, called capillaries.
