: PRéCIS: We generated a new visual field (VF) cluster map corresponding to Bruch membrane opening-minimum rim area (BMO-MRA) sectors, which described in detail the structure-function relationships between the optic nerve head and VF in patients with open-angle glaucoma. PURPOSE: The purpose of this study was to investigate the structure-function relationship between BMO-MRA and VF in patients with open-angle glaucoma. MATERIALS AND METHODS: We retrospectively reviewed 67 eyes of 50 patients with open-angle glaucoma who underwent spectral-domain optical coherence tomography for BMO-MRA and the Humphrey VF test. BMO-MRA of the glaucomatous optic nerve head was divided into 12 sectors. The correlation between BMO-MRA sectors and the VF points was analyzed to generate a new VF cluster map. RESULTS: Forty-three of the 52 VF points showed a significant correlation with at least 1 BMO-MRA sector. The VF cluster map was generated using the BMO-MRA sectors and each VF point that showed the most correlation. The superior hemifield correlated with 5, 6, 7, and 8 o'clock positions (ρ=0.312 to 0.710), whereas the inferior hemifield correlated with 10, 11, 12, and 2 o'clock positions (ρ=0.241 to 0.483). The VF cluster maps of superior and inferior hemifields showed different configurations of VF clusters and topographical relationships with the glaucomatous optic nerve head. CONCLUSION: The newly generated VF cluster map corresponding to BMO-MRA sectors showed a significant structure-function relationship and could be useful in the diagnosis and evaluation of glaucoma.
