Multimodal imaging of the left eye of a 54-year-old man with treatment naïve chronic CSC. a FAF showing the RPE aperture (arrowhead) as a well-circumscribed hypoautofluorescent macular area with a wide hyperautofluorescence nasally and a crescent-shaped faint hypoautofluorescence below. b, c Late-phase FA and ICGA revealing hyperfluorescent areas with some leaking points, and a perimacular window defect area. d SD-OCT horizontal line scan confirming intraretinal and subretinal fluid, with RPE aperture in correspondence of the PED (white asterisks). Six months later, after a full-fluence PDT session. e FAF showing the enlargement of the hypofluorescent macular area (arrowhead) and the transition from a faint hypoautofluorescence to a slight hyperautofluorescence inferior to the macula due to the subretinal fluid reabsorption. f SD-OCT revealing a complete resolution of subretinal fluid, with small intraretinal cysts and a flattening of the PED associated to a complete disappearance of the RPE (arrows). g–i OCT angiography image with corresponding B-scan displaying a roundish area of choroidal vessels beneath the RPE aperture as a result of a window defect
