Structure–function relationship between Bruch’s membrane opening-minimum rim width and perimetry in open-angle glaucoma subtypes

Purpose To seek the threshold value of Bruch’s membrane opening-minimum rim width (BMO-MRW) where visual field (VF) damage occurs in open-angle glaucoma (OAG) and explore whether there are structural differences between primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG).
