: To establish a normative database for macular and peripapillary vessel densities (VD) and foveal avascular zone (FAZ) metrics in healthy subjects with the new version of AngioScan software of RS-3000 Advance (Nidek Co, Ltd) optical coherence tomography angiography (OCT-A) device.: The study design was prospective and cross-sectional. VDs of the SCP, deep capillary plexus (DCP), retinal peripapillary capillary plexus (RPCP) and FAZ area, perimeter and circularity index (CI) along with the structural OCT measurements were scanned by using the Nidek's RS-3000 Advance OCT-A device in healthy subjects. The new version of the AngioScan software was used for analytics. The relations between the OCT-A parameters with age, gender and OCT parameters were analyzed.: A total of 128 right eyes of 128 subjects (50% female) were included in this study. We divided subjects into 3 groups in accordance with age; 19-39 years to Group 1, 40-59 years to Group 2, >60 y. to Group 3. The mean SCP and DCP VDs were 41.25 ± 2.51% and 36.01 ± 5.07% respectively ( < .001). The DCP VD was significantly different between groups ( = .001). The mean FAZ area, perimeter and CI were 0.33 ± 0.12 mm, 2.68 ± 0.6 mm and 0.47 ± 0.09 respectively. Only FAZ CI significantly differed between groups ( = .003). The FAZ area was significantly greater in female subjects than males ( = .025). The SCP and DCP VDs were inversely correlated with FAZ area and perimeter ( < .05).: Our study provided for the first time the normative data of the recently updated AngioScan software of Nidek. Additional studies are needed to define pathological vascular changes in ocular and systemic diseases with this new software.

Significance: Regular physical activity may affect the neurovascular structures. Many studies have shown the positive effects of physical activity on ocular disorders such as glaucoma, retinopathy, and macular degeneration. Athletes were expected to have a better retinal vascular structure compared with the nonathletes.

There was compared the effect of one medicinal leech on indicators of vasomotor function of endothelium of small resistance arteries and of middle arteries of muscular type. Stickiness index and augmentation index were determined in order to evaluate the medicinal leech effect on the rigidity state of arterial wall.
