Serous PED (A) appears as hyperreflective structures underneath the RPE that represent the choroidal neovascularisation (CNV) and fill out only part of the PED cavity [56]. Fibrovascular PED (B) are identified as the PED lesion’s cavity appears to be completely filled out by the CNV membrane [56]. fPEDs may be accompanied by variable quantities of serous exudation and/or haemorrhage; as a result the slope of the PED may vary depending on its fluid content [118].
