The innermost layer of the choroid in the eye, consisting of a network of tiny blood vessels that supply oxygen and nutrients to the retina.
From Latin chorio- (relating to the choroid) + capillaris (relating to capillaries, from capillus meaning 'hair' because capillaries are hair-thin).
The choriocapillaris is like an invisible delivery network behind your retina—millions of hair-thin blood vessels working 24/7 to feed your light-sensitive cells so you can see!
