Incipient non-arteritic anterior ischaemic optic neuropathy: a distinct clinical entity, the Singapore scene 3

ABSTRACT
We report five cases of non-arteritic anterior ischaemic optic neuropathy (NA-AION) where spontaneous resolution of the optic disc swelling occurred, and all relevant visual modalities were normal at presentation and remained so until resolution of the process after a median time of 9.6 weeks. This condition, which can be termed ‘incipient NA?AION’ or ‘threatened NA-AION’, should be recognised so that unnecessary investigations for other and more serious causes of optic disc swelling can be prevented.
Keywords: anterior ischaemic optic neuropathy, spontaneous resolution, visual acuity, visual fields
