Swept Source OCT Angiography Quantification in Optic Nerve Edema: Preliminary Results

OCT angiography (OCT-A) is a new imaging tool allowing the visualization of the superficial optic disc vessels and the superficial and deep peripapillary vascular network without any intra-venous dye injection. The morphological features of OCT-A in optic disc edema (papilledema, ischemic and inflammatory) have already been described. With the last development of Swept Source OCT-A software, it is possible to measure the peripapillary vessel density and the vascular flux. The aim of this study is to evaluate the relevance of these metrics in the diagnosis of optic disc edema.
