Reproducibility and repeatability of foveal avascular zone measurements in healthy subjects by optical coherence tomography angiography
Background/aims To assess the reproducibility and repeatability of foveal avascular zone (FAZ) area measurements using optical coherence tomography angiography (OCT-A) in healthy subjects. Methods Sixty healthy volunteers (60 eyes) were subjected to FAZ area measurements by means of high speed and high resolution spectral-domain OCT (SD-OCT) XR Avanti with the split-spectrum amplitude decorrelation angiography algorithm by two experienced examiners in two different sessions. Results The mean±SD age of the subjects was 28.9±7.6 years. Overall FAZ areas measured by the first and second observer were 0.251±0.096 mm 2 and 0.252±0.096 ...
