Relative reduction of the mean sectorial values of MRW and pRNFLT in each study group compared with healthy controls. The sectors with the greatest reduction for each group are highlighted in grey. NAION – non-arteritic anterior ischaemic optic neuropathy. CON – compressive optic neuropathy. OAG – open angle glaucoma. BMO – Bruch’s membrane opening. BMO-MWR – Bruch’s membrane opening minimum rim width. pRNFLT – peripapillary retinal nerve fibre layer thickness. ST – superotemporal. T – temporal. IT – inferotemporal. IN – inferonasal. N – nasal. SN – superonasal.
