The quantitative measurements of foveal avascular zone using optical coherence tomography angiography in normal volunteers

PurposeTo provide normative data of foveal avascular zone (FAZ) and thickness.
MethodsIn this cross-sectional study both eyes of each normal subject were scanned with optical coherence tomography angiography (OCTA) for foveal superficial and deep avascular zone (FAZ) and central foveal thickness (CFT) and parafoveal thickness (PFT).
ResultsOut of a total of 224 eyes of 112 volunteers with a mean age of 37.03 (12–67) years, the mean superficial FAZ area was 0.27 mm2, and deep FAZ area was 0.35 mm2 (P ConclusionThe gender and CFT influence the size of normal superficial and deep FAZ of capillary network.
