    Optical coherence tomography-angiography (OCT-A) has evolved quickly from an experimental technique to an essential tool, according to Eric Souied MD of the Centre Hospitalier Intercommunal Creteil, France. “Combining en-face OCT with movement detection within blood vessels, we get OCT-A, and with it a new imaging era,” said Dr Souied. Dr Souied described OCT-A as “a new, depth-resolved method to analyse the retinal and choroidal vascular structure.” Although it is an angiographic method, many characteristics set it apart from traditional fluorescein angiography (FA). It is non-invasive, due to its lack of dye. Because it is dye-less, there is no leakage, and ...
