Of the fundus
Retinal functions as an adjective meaning relating to the retina, the light-sensitive tissue at the back of the eye: retinal detachment, retinal scan.
As a noun, retinal is also a form of vitamin A essential for vision—the molecule in rod and cone cells that responds to light and enables sight.
