Optic nerve hypoplasia is characterized by which of the following?

Hypoplasia means underdevelopment. When this term is applied to the optic nerve, it means the nerve fibers are fewer than normal and the optic nerve is smaller than expected. This leads to a reduced or impaired visual signal from birth. It is not about inflammation, which would indicate optic neuritis; it is not about overdevelopment, and it is not a normal, healthy optic nerve. So the best description is underdevelopment of the optic nerve.
