(Summary description)Intraretinal “bridge”, a RAP revealed by 3D full range SS-OCTA! A 66-year-old female was found a round lesion at macular in her left eye because of blurred vision. High-resolution OCT B-scan showed local retinal detachment at macular with intraretinal hyperreflection connected to RPE close to fovea. “Double-layer sign” and RPE interruption were also observed (fig 1, yellow arrow). 6mm x 6mm full range OCTA was obtained centered fovea. The blood signal on avascular layer verified the existence of neovascularization. On B-scan image with blood signal overlayed, corresponding neovascularization was detected both inside the intraretinal hyperreflection lesion (fig 2, yellow arrow) and beneath RPE (fig 2, red arrow). This patient was diagnosed as retinal angiomatous proliferation (RAP) in her left eye. Retinal thickness in ETDRS rings and neovascularization area were quantified with build-in software for follow-up. 3D reconstruction showed how the neovascularization extended from deep vascular complex to beneath RPE (gif). TowardPi full range swept source OCT was used in this case to detect neovascularization. Numerous measurements and flow quantifications are available on the device. 3D structure and vessels can be easily obtained with build-in software.
