Aims: To explore the point-wise correlations between 10-2 visual field (VF) metrics and macular vessel density, as measured by optical coherence tomography angiography (OCTA), in patients with early open-angle glaucoma (OAG) and healthy controls. Methods: This is a cross-sectional study that retrospectively analyzed data from 54 participants (18 eraly OAG patients and 36 healthy controls) from the Zhongshan Ophthalmic Center. All participants underwent comprehensive ophthalmic examinations, 10-2 VF, and macular OCTA imaging. The correlation between capillary density (CD) in macular subregions and light sensitivity (LS) at corresponding VF test points was analyzed using Pearson's correlation coefficients. Results: The analysis revealed a significant reduction in CD within the inferior macular regions of glaucomatous eyes. Notably, there were strong point-wise correlations between CD and 10-2 VF, particularly in the inferior region of outer ring (peak r = 0.534, P < 0.001). Conclusion: The point-wise correlation between 10-2 VF and macular CDdemonstrates the potential for using CD to predict central VF damage in glaucoma, emphasizing theimportance of macular microcirculation in early disease screening.
