Papilledema

Swelling of the optic disc caused by increased pressure inside the skull. An important finding that requires urgent evaluation to identify the underlying cause.

2 min read

Papilledema is swelling of the optic disc specifically caused by elevated intracranial pressure (increased pressure inside the skull). It's usually bilateral (both eyes) and is an important warning sign that requires urgent investigation. For comprehensive information on causes, treatment, and prognosis, see Papilledema (Condition).

Key Takeaways

Optic disc swelling from elevated intracranial pressure
Usually affects both eyes
Urgent evaluation needed to find the cause
Vision may be normal initially but at risk
Different from other causes of disc swelling

Papilledema vs. Disc Edema

While often used interchangeably, technically:

Papilledema: Disc swelling specifically from elevated intracranial pressure
Disc edema: Disc swelling from any cause (inflammation, ischemia, compression, etc.)

This distinction matters because papilledema specifically indicates a problem with brain pressure. See Optic Disc Edema for the full differential diagnosis of disc swelling.

Clinical Appearance

Early Papilledema

Blurred disc margins (nasal first)
Hyperemia (redness) of disc
Loss of spontaneous venous pulsations
Subtle elevation

Established Papilledema

Elevated disc with obscured vessels
Peripapillary hemorrhages
Cotton wool spots
Exudates

Chronic Papilledema

Disc pallor developing
Vessel sheathing
"Champagne cork" appearance

Atrophic

Pale, flat disc
Permanent vision loss
Represents end-stage damage

When to Seek Urgent Care

Seek emergency evaluation if you have:

Severe headache with vision changes
New double vision with headache
Brief episodes of vision going dark (transient visual obscurations)
Swollen optic disc found on examination

Papilledema can indicate a brain tumor or other serious condition requiring urgent treatment.
