Optical coherence tomography angiography of the peripapillary capillaries in primary open-angle and normal-tension glaucoma - Fig 3

<p>(a) Pearson correlation coefficient matrix for flow density, structural variables, visual field, and clinical background in subjects with glaucoma. (Total patients) (b) Pearson correlation coefficient matrix for flow density, structural variables, visual field, and clinical background in subjects with glaucoma. (POAG group) (c) Pearson correlation coefficient matrix for flow density, structural variables, visual field, and clinical background in subjects with glaucoma. (NTG group). Fig 3a-c shows the correlations between FD, the disappearance angle of the RPCs, and other parameters. Fig3a shows the correlations in the overall population, Fig 3b shows the correlations in the POAG patients, and Fig 3c shows the correlations in the NTG patients. Abbreviations: OCT, optical coherence tomography; HFA, Humphrey field analyzer; RPC, radial peripapillary capillary; NFLD, retinal nerve fiber layer defect; PSD, pattern standard deviation; MD, mean deviation; cpRNFLT, circumpapillary retinal nerve fiber layer thickness.
