Review Of Related Diseases (RRD) 10 – Disorders Of The Neurological System Practice Test

Papilledema refers to which of the following?

Infection of the iris. Degeneration of the optic nerve. Edema and inflammation of the optic nerve where it enters the retina due to increased ICP. Inflammation of the cornea.

Correct Answer:

Edema and inflammation of the optic nerve where it enters the retina due to increased ICP.

Explanation:

Papilledema is swelling of the optic disc caused by increased intracranial pressure. When ICP rises, the pressure is transmitted along the optic nerve sheath, disrupting axoplasmic flow at the optic nerve head as it enters the retina, leading to edema of the optic disc. This is a hallmark sign and is typically bilateral. It is not an infection of the iris, not degeneration of the optic nerve, and not inflammation of the cornea. The description of edema of the optic nerve head due to increased ICP best fits papilledema.
