How will I know if I have papilledema?

The most common symptoms of high intracranial pressure are headache and visual loss. The headache may be located anywhere; frequently in the back of the neck. It is usually steady but may be pounding. It may be very severe, and unlike migraine, it may awaken the patient in the middle of the night. It also may worsen with bending or stooping. The optic nerve swelling may eventually lead to loss of vision seen as dimming, blurring or graying of vision. Patients may be aware of difficulty seeing to the side. Frequently patients notice visual disturbance lasting for a few seconds (often associated with bending or stooping). High pressure may cause damage to the nerves that move the eyes resulting in double vision. Patients may also be aware of a rushing noise in their ears. Nausea and vomiting may occur if the pressure is high and especially with a severe headache. Peripheral vision (detected on visual field testing) is usually abnormal and is one of the most important means of judging both the necessity for and effectiveness of treatment.
