Optical coherence technology-angiography (OCTA) is a novel, non-invasive motion-contrast imaging technique used to generate volumetric angiography images quickly. This video concisely reviews interesting OCTA data presented this yearâ€™s ARVO congress, which was held in Seattle, US (Sunday 01 May 2016, 15:15â€“17:00 PM, Session 146). Overall, OCTA has been shown to precisely identify retinal vessels and capillary nonperfused areas in eyes with diabetic retinopathy. However, the biggest drawback when applying this technique is that OCTA cannot provide any insight or information on the retinal periphery area, which is particularly important when evaluating and managing diabetic patients.
