OCT Angiography 29/11/2017

OCT Angiography (OCT-A) is a new, fast, non-invasive imaging modality that enables evaluation of the microvascular network of the retina.

OCT-A is capable of providing us with a 3-D image of the microvascular network of the retina and detecting capillary anomalies in patients with diabetic retinopathy and other retinal vascular diseases.

With OCT-A, the superficial vascular plexus and the deep capillary plexus can be examined in an isolated manner. This cannot be achieved using habitual techniques such as angiography with fluorescein or angiography with indocyanine green. For this reason, OCT-A gives us extra information.

This is carried out in the same way as optical coherence tomography (OCT). Unlike normal angiography, OCT-A does not require the application of an intravenous contrast agent.
