optic disc oedema

Swelling of the head of the optic nerve, as seen with an OPHTHALMOSCOPE at the inside of the back of the eye. Optic disc oedema may be a sign of optic nerve inflammation but commonly indicates a rise in the pressure within the skull from any cause, such as a brain tumour. It is thus a sign of high clinical significance. Also known as PAPILLOEDEMA.

Optic nerve ischaemia most frequently occurs at the optic nerve head, where structural crowding of nerve fibres and reduction of the vascular supply may combine to impair perfusion to a critical degree and produce optic disc oedema. The most common such syndrome is termed anterior ischaemic optic neuropathy (AION).
