We present a case of non-arteritic anterior ischaemic optic neuropathy (NAION) associated with ipsilateral internal carotid artery stenosis, in a patient who presented with sudden loss of vision. This patient underwent a carotid endarterectomy and reported both subjective and objective improvement in vision in the immediate postoperative period and a complete resolution of symptoms at 6 weeks follow-up. This case raises the question of a new indication for carotid endarter-ectomy in selected cases of NAION.
