Choroidal Neovascularization: OCT Angiography Findings
Type 1 CNV is observed in OCTA as a neovascular complex between the RPE and Bruch's membrane, originating in the choroid. The type 2 CNV is visualized as a neovascular network that grows from the choroid vasculature and traverses the RPE-Bruch's membrane complex into the subretinal space.
Managing CNV With OCTA - Retina Today
We know that an active hyper-signal on OCTA corresponds to CNV, but cases such as those that evolve toward extensive atrophy, scarring, and increased fibrosis need more than injections. Comprehensive multimodal imaging provides diagnostic information and specific treatment about these inflammatory CNV cases, which are distinctly different from ...

A review of optical coherence tomography angiography (OCTA)
2015年4月15日 · OCTA can detect changes in choroidal blood vessel flow and can elucidate the presence of choroidal neovascularization (CNV) in a variety of conditions but especially in AMD. It provides a highly detailed view of the retinal vasculature, which allows for accurate delineation of the foveal avascular zone (FAZ) in diabetic eyes and detection of ...
