Teaching NeuroImages: Distinguishing Papilledema From Pseudopapilledema Using Optical Coherence Tomography

A 71-year-old man presented to the emergency department with bilateral blurred optic discs, referred by his optometrist following a routine eye test. He had no visual or headache symptoms. Visual acuity was 20/20 bilaterally; funduscopy concurred with the optometry findings. Investigations for presumed papilledema were initially interpreted as normal (CT head/lumbar puncture). In clinic, optical coherence tomography (OCT) imaging identified optic disc drusen (ODD) (figure 1).
