Investigation of Vascular Pathology in Eye Diseases Using Using Optical Coherence Tomography Angiography (OCT-A)

Comparison of OCTA to conventional imaging modalities for the diagnosis of eye diseases

Optical coherence tomography angiography (OCTA) is a new non-invasive imaging technique that employs motion contrast imaging to high-resolution volumetric blood flow information. OCTA compares the decorrelation signal between sequential OCT b-scans taken at precisely the same cross-section in order to construct a map of blood flow. At present, level 1 evidence of the technology's clinical applications doesn't exist. The investigators plan to compare OCTA as an imaging modality to conventional imaging modalities used in clinical routine.
