Papilledema is a condition in which increased pressure in or around the brain causes the part of the optic nerve inside the eye to swell.

  • Symptoms may be fleeting disturbances in vision, headache, vomiting, or a combination.

  • Doctors make the diagnosis by looking in the person’s eye with an ophthalmoscope.

  • The disorder causing increased brain pressure is treated as soon as possible.

Causes of Papilledema

Symptoms of Papilledema

At first, papilledema may be present without affecting vision. Fleeting vision changes—blurred vision, double vision, flickering, or complete loss of vision—typically lasting seconds are characteristic of papilledema. Other symptoms may be caused by the elevated pressure in the brain. Headache, nausea, vomiting, or a combination may occur. This disorder does not cause pain.

Diagnosis of Papilledema

  • A doctor's evaluation

  • Imaging tests

  • Lumbar puncture (spinal tap)

To diagnose papilledema, a doctor uses an ophthalmoscope (a light with magnifying lenses that is used to look into the back of the eye). Often an ophthalmologist (a medical doctor who specializes in the evaluation and treatment of eye disorders) needs to confirm the diagnosis and help determine the cause.

Magnetic resonance imaging (MRI) or computed tomography (CT) may be used to help determine the cause and monitor the effect of treatment.

A sample of the cerebrospinal fluid may be examined for evidence of a brain tumor or infection.

Sometimes ultrasonography of the eye is done to distinguish between papilledema and other disorders that cause apparent swelling of the optic nerve.

Treatment of Papilledema

  • Treatment of cause

The disorder causing increased brain pressure is treated as soon as possible. For example, if the high pressure of the cerebrospinal fluid is caused by a brain tumor Overview of Brain Tumors A brain tumor can be a noncancerous (benign) or cancerous (malignant) growth in the brain. It may originate in the brain or have spread (metastasized) to the brain from another part of the body... read more , corticosteroids may be given, but surgery to remove the tumor or radiation therapy to decrease its size may be needed.

Papilledema that occurs as a result of idiopathic intracranial hypertension can be treated with weight loss and a diuretic. If unsuccessful, surgical procedures can be done.

An infection, if bacterial, can be treated with antibiotics.

A brain abscess is drained, and antibiotics are given.
