The optic disc is shaped like a doughnut with a pink neuroretinal rim and a central white depression called the physiologic cup.Check out the color of the neuroretinal rim, which carries the axons of the retinal ganglion cells. It should be orange-pink. If its axons die, the rim will turn white.he optic disc is shaped like a doughnut with a pink neuroretinal rim and a central white depression called the physiologic cup.
The optic disc is also known as the blind spot. It is a small region in the eye where the nerve endings of the retina enter the optic nerve. It also does not contain any rods â¦ or cones to convert images into nerve impulses.  It's some sort of a vein's attach point to the eye from the inside or something like that...plit and merge into it. Answer by Tom Wood. The blind spot in all mammals is the tiny area on the retina (light-sensing surface inside the eye) where the optic nerve exits the eye, carrying the optical signals to the brain.
