Purpose: The aim of this study was to assess the effects of age, gender, axial length and retinal thickness on the vascular density in a normal population using the Optovue optical coherence tomography angiography (OCT-A).Methods: A total of 209 eyes of 209 healthy subjects were scanned using the OCT-A on an outpatient basis. Patients were 20-75 years of age. The built-in software covered a 3x3 mm circle centered at the macula. The circle was divided into five sectors: a 1 mm central foveal circle and an upper, lower, nasal and temporal sector each spanning 1-3 mm away from the central circle. The vascular density (VD) at the superficial capillary plexus was measured, which spanned from the inner limiting membrane to the inner plexiform layer.Results: The fovea was the least dense area (32.5%+/- 5.9%), and the temporal area was the densest (52.4%+/- 4.4%). Similarly, the fovea was the thinnest part of the retina (237.8 +/- 20.7 mu m); however, the nasal sector was the thickest (308.5 +/- 15.1 mu m). We found a correlation of the retinal thickness (r=0.541, P
