Imaging of a 34-year-old male with pachychoroid neovasculopathy (PNV). (a) Optical coherence tomography (OCT) scans through the fovea show medium to high reflectivity beneath the retinal pigment epithelium (RPE). (b–d) OCT angiography (6 mm × 6 mm) reveals choroidal neovascularization (CNV) network vessels located between the detached RPE and Bruch’s membrane (highlighted by orange circles). (e,f) En face UWF SS-OCTA (24 mm × 20 mm) images display dilated vortex veins in the deep choroidal layer. The orange arrows in (e,f) mark the endpoints of dominant vortex vein dilation where CNV network vessels are observed. En face UWF SS-OCTA images correspond to the OCT angiography, showing CNV network vessels at the endpoint of the dominant vortex vein dilation.
