Observing 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.
在患者首次就诊时观察到视盘苍白常常会带来诊断挑战，尤其是在确定病因是青光眼还是其他形式的视神经病变方面。布鲁赫膜开口（BMO）最近被发现是视盘的解剖学边界。BMO最小边缘宽度（BMO-MRW）似乎是神经视网膜边缘的可靠指标。在我们的研究中，我们展示了BMO-MRW区分青光眼性和非青光眼性病变的能力。此外，我们提出了一种MRW比率，它可能有助于从非动脉性前部缺血性视神经病变或压迫性视神经病变中鉴别开角型青光眼。
