Detection of Glaucoma with an Optical Coherence Tomography-derived Neuroretinal Rim Parameter

I have read with great interest the article entitled “Enhanced detection of open-angle glaucoma with an anatomically accurate optical coherence tomography-derived neuroretinal rim parameter” by Chauhan et al, and I congratulate the authors for their informative paper. The study reported that the Bruch's membrane opening-minimum rim width (BMO-MRW)—an optical coherence tomography (OCT)-derived neuroretinal rim parameter—had better diagnostic performance for glaucoma than the current OCT-based optic nerve head (ONH) and retinal nerve fiber layer parameters. They suggested that the termination of Bruch's membrane (BM) or BMO is a logical anatomic outer border of the neuroretinal rim, and BMO-MRW is less affected by the plane (obliquity) of the optic disc. Although their study results provide valuable information, some aspects should be considered when analyzing neuroretinal rim thickness by using BMO-MRW in myopic eyes.
