Fluorescence angiography (FA) is widely used for studying and diagnosing abnormalities in the retinal blood circulation, but has associated risks of nausea, skin irritation, and even death. We describe a new non-invasive angiography technique: Blood Oxygenation Modulation Angiography, in which multispectral imaging of a transient perturbation in blood-oxygen saturation, yields angiography sequences similar to FA, including key features such as sequential filling of choroidal and retinal-vessels, which underpin assessment of circulation health. This is the first non-invasive angiography technique capable of visualizing these circulation features.

Choroidal Vasculature

Optical coherence tomography angiography (OCTA) is a non-invasive angiography type without a contrast agent, which provides a detailed assessment of the retinal and choroidal vasculature and visualisation of blood flow by detecting motions of erythrocytes, using serial optical coherence tomography B-scans. OCTA has been thoroughly investigated during imaging of the microvasculature in various retinal and choroidal vascular and tumoural diseases that affect the central macula. It has some important advantages and some acceptable disadvantages.
