Abstract
ABSTRACTObserving optic disc pallor during a patient’s first visit frequently raises a diagnostic challenge, particularly in regards to whether the cause is due to glaucoma or another form of optic neuropathy. Bruch’s membrane opening (BMO) was recently discovered as the anatomical border of the optic disc. BMO minimum rim width (BMO-MRW) seems to be a reliable representation of the neuroretinal rim. In our study, we demonstrate the ability of BMO-MRWs to differentiate between glaucomatous and non-glaucomatous. Additionally, we propose an MRW ratio which may allow discrimination of open angle glaucoma from either non-arteritic anterior ischaemic optic neuropathy or compressive optic neuropathy.
