    Pearse Keane and Reena Chopra

    Optical coherence tomography (OCT) is a routinely used non-invasive test that uses light waves to obtain cross sectional images of the retina. Optical coherence tomography angiography (OCTA) adds a new dimension to OCT; functional vascular network imaging. Pearse Keane, a Consultant Ophthalmologist at Moorfields Eye Hospital, has recently co-written a paper detailing the advantages and disadvantages of OCTA over conventionally used imaging tests. The paper explores the potential future development of this technique, and reviews the current literature on the clinical application of OCTA in common ocular diseases, including diabetic retinopathy, and retinal artery and vein occlusion. In this piece, Reena Chopra interviews Pearse on his research, and what implications it could have in primary eye care.
