Summary

ABSTRACT:
We report a typical illustration of Swept source OCT-Angiography (SS-OCT-A) findings in type 3 macular neovascularization(MNV) or retinal angiomatous proliferation (RAP).  This is a case of a 70-year-old Caucasian male patient presenting with an exudative type 3 neovascular age-related macular degeneration.
En face SS-OCT-A could non-invasively detect a tiny perifoveal circular “clew-like” high-flow neovascular lesion, visible in the deep capillary plexus, the outer retina and communicating with the choriocapillaris, with a perilesional dark halo and associated to no-flow macular cysts in the deep capillary plexus slab. En face SS-OCT-A could also highlight the presence of a telangiectatic capillary dilation in the superficial capillary plexus appearing to be at the origin of the retinal neovascularization. Cross-sectional SS-OCT-A showed an intra-retinal vertical high vascular flow within the hyper-reflective neovascular lesion, with a typical hyperreflective “kissing sign” and associated to subretinal and intraretinal fluid.
In conclusion, en face OCT-A is useful tool to diagnose type 3 MNV or RAP non-invasively and associated cross-sectional OCT-A scan is very helpful highlighting the linear vascular high-flow within the retinal neovascularization.
