Papilledema is a key diagnostic factor in the management of several neurological conditions. Papilledema has a variety of causes related to increased intracranial pressure (ICP), several of which require prompt surgical or medical intervention due to potential vision or life-threatening consequences. Magnetic resonance imaging (MRI) of the brain is key to making the correct diagnosis and management decisions. Case Report: This case report illustrates acute onset papilledema in a young Caucasian male due to acquired hydrocephalus from a rare condition, idiopathic stenosis of the foramen of Monro. An MRI performed following the eye examination prompted a referral to neurology and neurosurgery for urgent intervention, leading to eventual good visual outcome for the patient. The important role of eye care providers in diagnosis, referral, and post-surgical management is emphasized.
