What is a common symptom associated with papilledema?

Papilledema refers to the swelling of the optic disc due to increased intracranial pressure, and the most common symptom associated with it is a swollen optic disc. This condition can result from various causes such as brain tumors, traumatic brain injury, or conditions causing increased intracranial pressure. The presence of bulging around the optic nerve head is a direct indication of papilledema.

Unlike the other symptoms listed, which pertain to different systems or conditions, the swollen optic disc is a direct manifestation of changes occurring in the optic nerve due to pressure. Therefore, identifying the swollen optic disc during an eye examination is crucial for diagnosing underlying conditions that may be leading to increased intracranial pressure and managing the patient's health effectively.
