What is papilledema?

Papilledema refers to the swelling of the optic disc, which is the area where the optic nerve enters the eye. This swelling is typically caused by increased intracranial pressure, which can result from various conditions, such as tumors, head injuries, or central nervous system diseases. When the pressure rises, it affects the optic nerve head, leading to the characteristic swelling that can be observed during a regular eye examination.

Recognizing papilledema is crucial in clinical practice because it often indicates serious underlying health issues requiring immediate attention and evaluation. Its identification can lead healthcare professionals to investigate the cause of increased intracranial pressure, providing insights into potential neurological conditions.
