Anterior ischaemic optic neuropathy. II. Fundus on ophthalmoscopy and fluorescein angiography.

Abstract

The classical description of the fundus appearances in anterior ischaemic optic neuropathy (AION) is that of pale oedema of the optic disc (OD), usually accompanied by OD and peripapillary haemorrhages, and invariable optic atrophy in later stages. These are almost always considered to be the only fundus findings, although the presence of "exudates" at the posterior pole has occasionally been mentioned. The retinal vessels are usually des- cribed as being normal.
