Interchangeability and reliability of macular perfusion parameter measurements using optical coherence tomography angiography

AimThe aim of the study was to investigate the interchangeability and reliability of macular perfusion measurements using optical coherence tomography angiography.MethodsA prospective cross-sectional observational study. Healthy adult Chinese subjects were recruited. Macular perfusion parameters were automatically analysed by software included in a spectral-domain optical coherence tomography system. The vessel density (VD) of the whole, parafovea, superior-hemi, inferior-hemi, fovea, temporal, superior, nasal and inferior quadrants as well as the foveal avascular zone (FAZ) and choroidal capillary VD (CCVD) were quantified.ResultsA total of 51 eyes in 27 subjects were included (8 men and 19 women, mean age 24±4 years). Significant differences in VD of all quadrants (all p
