Bilateral anterior ischaemic optic neuropathy in a patient with haemochromatosis.

Traumatic ischaemic optic neuropathy.

Persistent profound visual loss following contusion of the globe or ocular adnexae has been well documented, the visual loss being attributed to haemorrhage into, or contusion of, the optic nerve, or to interference with the blood supply of the eye. The patient described below presented after a contusion of the eye and orbit, with the clinical picture of ischaemic optic neuropathy presumably re...
