We measured the retinal blood flow in the parapapillary area in 17 eyes of 17 patients with normal-tension glaucoma (NTG) with localized visual field defect either in the superior or inferior visual field. Another series of 7 eyes of 7 healthy persons served as control. The measurement was made using a Heidelberg Retina Flowmeter. There was no difference in the blood flow volume between the superior and inferior parapapillary retina in the control group. In the NTG group, a significant decrease in blood flow volume was present in the area of visual field defect (p < 0.002). Similar decrease was present in blood flow and velocity only in superior or inferior temporal area. There was a significant correlation between blood flow and retinal sensitivity (p <0.05) . The findings show impaired circulation in the parapapillary area is closely associated with visual field defect in eyes with NTG.
