Region where ganglion cell axons leave the eye as the optic nerve?

• A. Optic Disc
• B. Macula
• C. Fovea
• D. Lamina Cribrosa

Answer: (A)

The point where retinal ganglion cell axons converge and exit the eye to form the optic nerve is the optic disc (optic nerve head). This region marks the boundary where the retina gives way to the optic nerve, and it’s why it’s called the blind spot—there are no photoreceptors there. The macula and fovea are central retina areas dedicated to sharp, detailed vision, not where the fibers exit. The lamina cribrosa is a sieve-like structure within the sclera through which the fibers pass after they have left the eye; the actual exit from the eye is at the optic disc.
