Ischaemic optic neuropathy following bilateral neck dissection

Two cases of ischaemic optic neuropathy, which occurred as a complication o f oncological neck surgery, are reported. These cases are submitted because of the apparent scarcity in the literature of this complication after head and neck surgery. They are also unusual because they presented with differ ent clinical manifestations of ischaemic optic neuropathy after separate fo rms of bilateral neck dissection. A literature review identifies a small nu mber of similar cases and risk factors and preventative measures are discus sed.
