Which ocular condition is commonly associated with an elevated optic nerve?

The condition commonly associated with an elevated optic nerve is papilledema. Papilledema refers to the swelling of the optic disc due to increased intracranial pressure. This pressure can result from various underlying issues such as tumors, hemorrhages, or conditions that cause fluid accumulation. When there is elevated pressure in the cranial cavity, it transmits to the optic nerve sheath, leading to the characteristic findings of papilledema during an eye examination.

In contrast, while conditions like glaucoma can also affect the optic nerve, they typically result in atrophy or cupping of the nerve head rather than elevation. Cataracts are related to the lens of the eye and do not cause optic nerve swelling, and retinal detachment involves the separation of the retina from the underlying supportive tissue but is not directly associated with optic nerve elevation.
