Which finding is typical in acute papilloedema?

Acute papilloedema is characterized by significant swelling of the optic disc, which is often associated with increased intracranial pressure. The presence of distended retinal veins is a typical finding due to the obstruction of venous outflow from the retina, which occurs as the pressure in the cranial cavity rises. This congestion leads to visible swelling in the blood vessels of the retina.

The absence of spontaneous venous pulsation (SVP) is another notable finding associated with acute papilloedema. Normally, there is a rhythmic pulsation of the retinal veins that corresponds with the cardiac cycle; however, this is often absent when papilloedema is present due to the increased pressure in the optic nerve sheath that compresses the venous vessels.

Therefore, the correct response is the choice that includes both the finding of distended retinal veins and the absence of SVP, reflecting the notable changes that occur in acute papilloedema as a result of elevated intracranial pressure.
