Regional Comparisons of Optical Coherence Tomography Angiography Vessel Density in Primary Open-Angle Glaucoma

Diagnostic ability of the vessel density parameters of OCTA was only moderate. Macular and inside disc densities had significantly lower diagnostic abilities in POAG than the peripapillary density. Diagnostic abilities of vessel densities increased with increasing severity of glaucoma and that of ONH vessel density with higher pretreatment IOPs.
