Does the optic nerve pass through the foramen ovale?
The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
Which term describes the region in the eye where the nerve endings of the retina gather to form the optic nerve?
optic disk
What term describes the region in the eye where the nerve endings of the retina gather to form the optic nerve?
optic disk
Why is there no sensation of light at the optic disk?
Because there are no rods or cones there, since the optic disk is where axons exit the eye to form the optic nerve.
Area of the retina that lacks rods and cones?
The retina is filled with rods and cones- except for one spot. This place that lack rods and cones is called the blind spot, which can be found by covering up one eye and looking at something with the other. Out of the corner of your uncovered eye, you will will see something disappear. We don't realize it on a daily basis because our brain fills in the empty spot. The blind spot is located near the optic nerve and is about 2mm wide.
Where does the optic nerve leave the eye?
The optic nerve exits the retina at the optic disc, otherwise known as the "blind spot".

What is significance of an enlarged optic disk?
I found an article on optic nerve....link is below.
Condition is swelling of the optic nerve at the point of entrance through the optic disk?
papilledema
Is everyone's blind spot different?
Yes it is located on the optic disk in the back of each eye where the optic nerve attaches to the retina
What is the function of the optic disk in the eye?
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.
What is the function of optic disk?
It's the place in the eye where axons exit the eye to form the optic nerve, and where blood vessels enter to nourish the retina.
