Optic nerve dysplasia is described as what?

• A. Misshapen optic nerve
• B. Enlarged optic cup
• C. Normal optic nerve
• D. Optic neuritis

Answer: (A)

The idea being tested is what optic nerve dysplasia looks like. Optic nerve dysplasia is a developmental malformation of the optic nerve head, so it tends to appear as a misshapen, irregular optic disc rather than a normal round nerve. This contrasts with an enlarged optic cup (which points to cupping from glaucoma or optic neuropathy), a normal optic nerve (no dysplasia), or optic neuritis (inflammatory optic nerve with swelling during an acute episode). Therefore, describing optic nerve dysplasia as a misshapen optic nerve best reflects its irregular, malformed appearance.
