The outer layer of the retina of the eye, derived from the outer layer of the embryonic eye cup.
From Greek 'ektos' (outside) and Latin 'retina' (network), referring to the outermost neural layer. A specialized anatomical term used in developmental biology and ophthalmology.
The ectoretina develops from structures inside your eye during pregnancy and becomes the pigmented layer that prevents light from bouncing around—it's like your eye's light-blocking paint job!
