The place of OCT‐angiography in uveitis

SummaryOptical coherence Tomography (OCT) angiography is a newly developed, dye‐less, imaging method that provides high‐resolution, depth‐resolved en face images of the retinal and choroidal microvasculature. OCT angiography has shown to be helpful in evaluating retinal vasculitis. It is better than fluorescein angiography in detecting perifoveal retinal ischemia and other microvascular changes. In such cases, the deep capillary plexus appears to be more severely involved than the superficial capillary plexus. On the other hand, OCT angiography may play a critical role in the differential diagnosis, evaluation, and monitoring of various choroidal inflammatory diseases involving the macula. It may show evidence of choroidal flow reduction. In these conditions, the choriocapillaris seems to be the primary site of a reversible or persistent ischemic process. OCT angiography is also useful for noninvasive detection of inflammatory choroidal neovasculization, and for monitoring of its response to therapy. Further studies are needed to definitely establish the role of OCT angiography in the diagnosis and management of retinal and choroidal inflammatory conditions and in assessing predictive factors for visual outcome.
