Overview
Brief Summary
Optical coherence tomography angiography (OCT-A) is a determinant progress to study retinal and choroidal vasculature without using a dye injection. 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.
