Step-by-step explanation:
The condition called when there is swelling of the optic disc due to increased intracranial pressure is papilledema. Papilledema is caused by increased pressure within the skull, which can be a result of conditions such as brain tumors or meningitis. This swelling can compress the optic nerve and lead to vision problems.
For example, in the case of meningitis, the swelling around the optic nerve can push on it and cause vision loss.
