1. The statement, ‘the optic nerves are elevated’ is confusing. Do you mean the vessels in the disc, or optic nerve heads in which case you are referring to both eyes, but only one disc picture is provided. All the same it’s a challenging quiz as I thought of Glaucoma and morning glory. Thanks.

    1. Difficult to illustrate in a two-dimensional photograph but both the optic nerve head and the vessels arching over it are elevated. The vessels are not elevated above the surface of the optic nerve head, however.
