Abstract
Presentation Description :
OCT angiography (OCTA) OCT is a novel imaging modality that employs amplitude or phase decorrelation technology with high-frequency and dense volumetric scanning to detect the motion of blood flow, allowing direct visualization of blood vessels in vivo without the use of exogenous dyes. Unlike fluorescein or indocyanine angiography, depth resolved visualization of normal and abnormal microvascular structures of the retina and choroid may be achieved. This presentation will review the OCTA results of the detailed morphological analysis of type 1 neovascular lesions originating from the choroid and located under the retinal pigment epithelium. The results of the OCTA structural analysis of type 3 intraretinal neovascular complexes, that originate from the deep retinal capillary plexus, will also be presented and these findings will be compared with the OCTA analysis of type 1 lesions. Further, we will summarize the quantitative and qualitative OCTA findings of both type 1 and type 3 neovascular lesions before and after antiVEGF therapy and provide parameters that may be valuable in the future application of OCTA for the optimal evaluation and management of neovascular age related macular degeneration (AMD).
