What finding is characterized by swelling of the optic disc due to increased intracranial pressure?

The finding characterized by swelling of the optic disc due to increased intracranial pressure is known as papilledema. This condition occurs when there is a rise in pressure within the skull, which can be caused by various factors, including brain tumors, head injuries, or conditions that lead to increased cerebrospinal fluid (CSF) production or decreased drainage.

In papilledema, the swelling can be visualized during a fundoscopic examination, where the optic disc appears elevated and blurred at the edges, indicating the presence of edema. It's important to recognize this condition, as it can signal serious underlying health issues that require further investigation and management to prevent potential complications, including vision loss.

Normal optic disc appearance would show a healthy, flat disc without swelling, while optic neuropathy refers to damage to the optic nerve itself, which is not specifically characterized by swelling of the disc. Retinal detachment involves the separation of the retina from its underlying tissue and does not involve the optic disc swelling associated with increased intracranial pressure.
