Papilledema is a condition that is caused by swelling of the optic nerve. The optic nerve is the nerve that connects the back of the eyeball and the retina with the brain. As such the slightest swelling of intracranial pressure can compress the optic nerve. Hence, when this nerve develops any inflammation on its own or is exposed to high pressure it can budge on the rear wall of the eyeball leading to this malady.
Some of the most common causes for papilledema are brain infections, brain tumor, encephalitis, brain abscess and high blood pressure.
Symptoms of papilledema include nausea with vomiting and severe headache. Visual changes and visual blackouts are also found in people suffering from advanced and severe papilledema. These are also optic neuritis symptoms which can occur as a side effect of papilledema. In certain cases, optic neuritis symptoms can lead to temporary vision loss as well.
The choice of papilledema treatment completely depends on the cause. While a surgery may be needed if this malady is caused due to brain tumor. Generally medicines are prescribed for papilledema treatment when it occurs due to high blood pressure in the patients.
