Alterations of the outer retina in non‐arteritic anterior ischaemic optic neuropathy detected using spectral‐domain optical coherence tomography

Background A characteristic disease pattern may be reflected by retinal layer thickness changes in non‐arteritic anterior ischaemic optic neuropathy measured using spectraldomain optical coherence tomography. Retinal layer segmentation is enabled by advanced software. In this study, retinal layer thicknesses in acute and chronic non‐arteritic anterior ischaemic optic neuropathy were compared. Design A single‐centre cross‐sectional analysis was used. Participants A total of 27 patients (20 age‐matched healthy eyes) were included: 14 with acute (
