Optical coherence tomography angiography (OCT-A) was developed as an extension of OCT imaging. This technology allowed for the visualization of retinal microvasculature in vivo , without the need for contrast dye, provides depth-resolved images of blood flow in the retina and choroid with levels of detail far exceeding that obtained with older forms of imaging. OCT-A has been recently used for noninvasive evaluation of macular and peripapillary capillary network alterations in diabetic retinopathy, and the ability to clearly visualize microvascular changes has allowed for a better assessment of the microvascular retinal alterations, retinal ischemia, and neovascularization in diabetic macular edema (DME) patient. The present paper aims to review the most recent information about the findings for diagnostic interpretation in DME using OCT angiography.
