Purpose: To investigate venous total retinal blood flow (TRBF) and retinal blood flow (RBF) in the superior and the inferior retinal hemifields in primary open angle glaucoma (POAG) patients with, and without, disc hemorrhage (DH). Methods: RBF measurements were obtained from 10 POAG with DH and 19 POAG without DH using Doppler SD-OCT (RTVue) as well as bi-directional laser Doppler flowmetry (CLBF). Results: RBF was not different between the superior and inferior hemifields for either of the two groups. Venous TRBF in the POAG with DH group was significantly lower than in the age-matched stable POAG without DH group (p=0.009). In the POAG with DH group, venous TRBF was significantly lower in the DH eye compared to contralateral eye without DH (p=0.015). Conclusions: Venous TRBF was significantly lower in the POAG with DH group compared to both the POAG without DH group and the contralateral eye of the POAG with DH group.
