The entrance of optic nerves into the retina.
The point on the retina where the optic nerve starts.
A small circular portion of the retina where the optic nerve passes through and does not have visual capacity.
Otherwise known as the blind spot of the eye, the disc is the beginning of the optic nerve the point where nerve fibres from the retina’s rods and cones (the light- and colour-sensitive cells) leave the eyeball.
The small blind spot on the surface of the retina where cells of the retina converge to form the optic nerve; the only part of the retina that is insensitive to light.
The optic disc is a region on the retina, which is the light-sensitive layer at the back of the eye, where nerve fibers from the eyeball connect to the optic nerve. It’s often referred to as the blind spot due to its absence of light-sensitive cells.
The tiny region at the rear of the eyeball where the optic nerve and retinal blood vessels enter. This area doesn’t respond to light, and variations in its look can aid in identifying specific medical conditions.
