Fleeting vision changes—blurred vision, double vision, flickering, or complete loss of vision—typically lasting seconds are characteristic of papilledema. Other symptoms may be caused by the elevated pressure in the brain. A pulsating whooshing noise in the ears, headache, nausea, vomiting, or a combination may occur.
May 15, 2024 · Papilledema occurs when raised intracranial pressure is transmitted to the optic nerve sheath. The raised pressure mechanically disrupts axoplasmic flow within the nerve. Obstipation of intra-axonal fluid results in swelling of the axons and leakage of water, protein, and other cellular contents into the extracellular space of the optic disc ...
Jun 22, 2023 · Papilledema is the swelling of the optic nerve as it enters the back of the eye due to raised intracranial pressure. Fluid surrounding the brain is constantly produced and reabsorbed, maintaining just enough intracranial pressure to help protect the brain if there is blunt head trauma.
Papilledema refers to swelling of the optic discs secondary to increased intracranial pressure, and occurs when axonal transport is interrupted at the optic disc head. 1 Often, ophthalmologists will make the diagnosis serendipitously and then initiate the medical evaluation to identify the underlying, possibly life-threatening intracranial or ...
Jun 19, 2024 · Although papilledema literally means swelling of the optic disc (nerve head/papilla), in ophthalmological parlance, it is only one of many causes of optic disc edema 8-10. Furthermore, it should also be distinguished from causes of pseudo-edema from optic disc drusen 9 .
