Imaging of a 48-year-old male with pachychoroid neovasculopathy (PNV). (a) Optical coherence tomography (OCT) scans through the fovea reveal medium- and high-reflectivity beneath the retinal pigment epithelium (RPE). (b–d) OCT angiography (6 mm × 6 mm) shows choroidal neovascularization (CNV) network vessels situated between the detached RPE and Bruch’s membrane (highlighted by orange circles). (e,f) En face UWF SS-OCTA (24 mm × 20 mm) images depict dilated vortex veins in the deep choroidal layer. The orange arrows in (e,f) mark the sites of symmetric vortex vein dilation and anastomosis, where CNV network vessels are observed. En face UWF SS-OCTA images align with the OCT angiography, indicating CNV network vessels at the site of symmetric vortex vein dilation and anastomosis.
