Where is the optic disc located?

• A. Retina
• B. Cornea
• C. Iris
• D. Lens

Answer: (A)

The optic disc is located on the retina. It’s the point where the nerve fibers from the retina converge to form the optic nerve and exit the eye, creating the natural blind spot because there are no photoreceptors there. This place is on the inner surface of the retina, where blood vessels also enter and exit. The other structures—cornea, iris, and lens—are all in the anterior part of the eye, involved in focusing and regulating light, not the location where the optic nerve connects to the retina.
