Symptoms and Causes
What are the signs and symptoms of papilledema?
You may have no symptoms (be asymptomatic), though you may have:
- Headaches: Headaches related to papilledema may be worse in the mornings and when you’re lying down.
- Transient visual obscurations: These events are periods of about five to 15 seconds where your vision gets blurry, goes gray, or blacks out. An obscuration is similar to what happens during a total eclipse when the moon blocks the sun from your sight. These events usually happen when you change posture. You can have these events in both eyes (bilateral) or in only one eye (unilateral).
- Double vision (diplopia): This may happen if the intracranial hypertension results in a cranial nerve palsy that impairs the eye muscles.
- Nausea and vomiting.
- Neurological symptoms: These may include problems with movement or thinking.
