The optic disc is crucial to the eyes. It functions as an entry point for the vessels which supply blood to the retina.
The optic disc in the human eye is the part of the eye that is connected to the retina and carries visual information to the thalamus and other parts of the brain.
The optic nerve exits the retina at the optic disc, otherwise known as the "blind spot".
Optic disc:The optic disc is also called the blind spot. There are no receptors in this part of the retina. This is where all of the axons of the ganglion cells(last neurons before optic nerve) exit the retina to form the optic nerve.
The optic nerve enters the eye at the back of the eyeball through an opening called the optic disc. This area is also known as the blind spot because it lacks light-sensitive cells (rods and cones) that are present in other parts of the retina.
This spot is where the optic nerve and blood vesicles enter the eye and it is called the "optic disc".
Point where optic nerve enters eyeball is the optic disc.
The optic disc or blind spot is where optic nerve leaves the back of the eye. There are no photoreceptors (rods/cones) in that area.
