Comparative study of retinal nerve fibre layer thickness and retinal peripapillary capillary plexus microvascular vessel density: structure–function relationship analysis in glaucoma

To investigate whether the retinal peripapillary capillary plexus vessel density (RPCP VD) or the retinal nerve fibre layer thickness (RNFLT) is better in showing the structure-function relationship in glaucoma.Sixty-seven patients with primary open-angle glaucoma (POAG) in one eye and no visual field loss in fellow eye were included in this study. The scans of RPCP VD and RNFLT, and the standard automated perimetry data [including mean...
