‘OCT ANGIOGRAPHY, GOING WITH THE FLOW’, PRESENTED BY NISHAL PATEL 

Reviewed by Daniel Hardiman-McCartney FCOptom.

Looking to find out more about optical coherence tomography angiography (OCTA), I decided to attend the session on the topic. OCTA is a way of imaging blood vessels and blood flow in the retina and choroid. Nishal Patel, an eye surgeon and researcher based at King’s College School of Medicine, explained that OCTA works by comparing the data from several OCT scans captured at the same location taken successively and at high speed. Motion contrast changes are calculated and extracted from the image data to depict the structure, function and flow of the retinal vasculature, including the choroidal capillaries. Different layers of the retinal vasculature can be separated and viewed layer by layer.
