PURPOSE: To investigate the effect of blood flow in the temporal optic nerve head (ONH) and peripapillary chorioretinal atrophy (PPA) zone on central visual field (VF) defects and progression in eyes with open-angle glaucoma (OAG) and myopic disc. DESIGN: Retrospective longitudinal medical chart review. PARTICIPANTS: This study comprised 366 eyes of 245 OAG patients with myopic disc, followed for at least 2 years with at least 5 reliable VF tests. OCT and laser speckle flowgraphy (LSFG) were performed at baseline. METHODS: We analyzed the relationship between temporal ONH-tissue mean blur rate (MBR), temporal PPA-tissue MBR, total deviation (TD)-central, and TD-central slope with a linear mixed-effects model. Additionally, we investigated background factors influencing temporal PPA-tissue MBR. Main outcome measures were basic ophthalmic and systemic variables, baseline ONH-tissue MBR, baseline PPA-tissue MBR, baseline TD, and TD slope. RESULTS: Lower temporal ONH-tissue MBR was associated with both worse TD-central and faster TD-central slope (β = 0.30, P < 0.001; β = 0.18, P = 0.001, respectively). However, lower temporal PPA-tissue MBR was only associated with faster TD-central slope (β = 0.15, P = 0.005). Lower ONH-tissue MBR and lower PPA-tissue MBR were significant independent contributors to worse TD-central slope, after adjusting for potential confounding factors (β = 0.12 to 0.15, P < 0.05). The multivariate analysis showed that lower pulse rate, larger temporal PPA area, and lower circumpapillary retinal nerve fiber layer thickness were associated with lower PPA-tissue MBR (P < 0.05). CONCLUSIONS: Measurement of systemic variables and LSFG analysis might help clinicians to predict central VF defect severity and progression in OAG eyes with myopic disc.
