Optic nerve dysplasia is described as which of the following terms?

• A. Misshapen optic nerve
• B. Optic nerve atrophy
• C. Normal optic nerve
• D. Normal color vision

Answer: (A)

Optic nerve dysplasia is a congenital malformation of the optic nerve, so the description you’d expect is a misshapen optic nerve. This reflects abnormal development of the nerve fibers and the optic disc itself from birth. It’s different from optic nerve atrophy, which is degeneration that occurs after injury or disease and isn’t a primary malformation. A normal optic nerve would be inconsistent with dysplasia, and normal color vision doesn’t capture the structural abnormality described by dysplasia.
