Papilledema means that the optic disc of your eye is swollen. The optic disc is part of the nerve that carries information from the eye to the brain (optic nerve). Papilledema usually affects both eyes.
Papilledema is usually caused by high pressure in the fluid around your brain. If that is what's causing your papilledema, you will need to get tests done right away to try to find the reason for the high pressure.
