What is optic disc?

The optic disc: Is the location where ganglion cell axons exit the eye to form the optic nerve. There are no light sensitive rods or cones to respond to a light stimulus at this point. This causes a break in the visual field called the blind spot.

Eye structure: The optic disc is the structure at the back of the eye where the visual nerves come together to form the optic nerve and where blood vessels enter and exit the back of the eye. Its health and structure are clues to various diseases such as multiple sclerosis, glaucoma and other conditions.
