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.

There is vasoconstriction of the posterior ciliary arteries supplying the optic nerve head, which leads to optic disc oedema.

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.
