Purpose: to investigate the reproducibility and reliability of OCT-A vascular measurements using Heidelberg Spectralis II OCT-A. Methods: a prospective study involving single eye patients aged 18 or older with no ocular disease. In order first second scans, coefficient variation foveal avascular zone (FAZ) vessel density (VD) in superficial (SCP), intermediate (ICP) deep capillary plexus (DCP) were calculated. Results: A total 75 eyes included study. The mean FAZ scan was 0.36 × 0.13 mm2 0.37 0.12 mm2, respectively, SCP, 0.23 0.10 0.09 ICP, 0.42 0.11 0.43 DCP. overall VD 36.05 9.01 35.33 9.92 at scan, 21.87 5.00 21.32 5.56 23.84 6.53 23.20 6.83 No statistically significant differences all sectors each observed between (p > 0.05). Conclusion: our demonstrated good analysis quantification retina.
