The choroid layer is essential for the health of the retina.
The dark-brown layer of blood vessels in the eye that is located between the outer layer (sclera) and the inner layer (retina).
The choroid helps supply blood to the retina, ensuring it receives the nutrients it needs.
Choroid is formed from "choroides" (from Greek, meaning resembling the chorion, which is the outer membrane of an embryo) and "-oid" (meaning like or resembling). The word "choroid" refers to a structure that resembles the chorion, specifically the vascular layer of the eye between the retina and the sclera.
Think of the Greek word for the outer membrane ('choroides') to remember that 'choroid' refers to a layer in the eye that resembles this outer structure.
