Application of OCTA in primary open angle glaucoma
AIM: To observe the vascular density of optic disc region in radial peripapillary capillaries(RPC)layer of normal people and primary open argle glaucoma(POAG)patients using OCTA, and to explore the diagnostic ability of this technique for POAG.<p>METHODS: This study was a cross-sectional study...
