Optic Disc Vascular Density in Normal-Tension Glaucoma Eyes with or without Branch Retinal Vessel Occlusion

We analyzed the vascular densities (VDs) of optic disc areas in eyes with normal-tension glaucoma (NTG) according to their branch retinal vessel occlusion (BRVO) status. The VDs discs and peripapillary 68 NTG patients BRVO (BRVO group; fellow eyes) 37 alone (control were measured on angiographic images obtained via swept-source optical coherence tomography angiography. compared among groups correlations assessed. VD large was highest eyes, followed by controls (all P < 0.05). Conversely, small medium opposite order Large negatively correlated (r = −0.697, 0.001). Peripapillary lower than control (P 0.001 0.861, respectively). In conclusion, significant changes distribution for larger vessels observed both BRVO, without BRVO.
