A large number of such cases have been reported in the literature, but, although this clinic...

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...

Anterior ischaemic optic neuropathy: recurrent episodes in the same eye.

It may be associated with giant cell arteritis but is usually idiopathic. Although subsequent involvement of the second eye is common, more than one episode in the same eye is extremely rare. Four patients with recurrent anterior ischaemic op...
