Swelling of the optic nerve that can be seen in the back of the eye with an opthalmoscope; it may occur when the blood pressure is severely elevated.
A swelling of the head of the optic nerve, usually due to increased intracranial pressure.
Swelling of the optic disc, the beginning of the optic nerve, usually associated with increased intracranial pressure.
Inflammation and edema of the optic disc caused by increased intracranial pressure from a brain tumor or head trauma; also known as a choked disc.
Swelling of the region where the optic nerve joins the retina (the thin, light-sensitive area in the back of the eye). Papilledema is caused by increased intracranial pressure, and both eyes are usually involved. Papilledema can result from a brain tumor, bleeding into the brain tissue, or pseudotumor cerebri. Malignant hypertension, a medical emergency, may also cause disc swelling.
Swelling of the optic nerve with dilated veins, blurred optic disc margins, flame-shaped hemorrhages in the nerve fiber layer adjacent to the disc, and an enlarged blind spot on the visual field. It is caused by increased intracranial pressure, often due to a tumor of the brain pressing on the optic nerve. Blindness may result very rapidly unless relieved.
The enlargement that arises around the optic nerve. The presence of papilledema signifies heightened pressure within the skull.
Swelling of the optic disc accompanied by constricted arteries and enlarged veins. It’s also known as choked disc, optic neuritis, or papillitis.
