OCT-A yields interesting results in different pathologies such as diabetes mellitus, age-related macular degeneration, hypertension blood pressure, particularly by affecting vascular density. Normative database are necessary to compare OCT-A parameters between patients and controls. However, OCT-A devices from different manufactures may give different values for the same subject. It seems to be obvious that each OCT-A device should have its own normative database. In the literature, OCT-A normative databases are developing using different types of devices, but none is available for Heidelberg OCT-A in Caucasians. The purpose of this project is to create a normative database of retinal microvascularisation using Spectralis Heidelberg optical coherence tomography angiography (OCT-A) ® in normal controls.",[70,71],"Optical Coherence Tomography","Optical Coherence Tomography Angiography",[73,74,75,17,76,77],"Normative database","Healthy subjects","Optical coherence tomography","Heidelberg","Vascular density","2024-09-24",{"date":80,"type":81},"2024-09-26","ACTUAL",{"date":83,"type":81},"2023-06-12",{"date":85,"type":64},"2026-09",{"name":5,"class":6},1]
