Figure 2: SD-OCT showing progressive quantitative increment in the size of the double-layer sign as the pachychoroid spectrum progresses from pachychoroid pigment epitheliopathy (a), to central serous chorioretinopathy (b), pachychoroid neovasculopathy (c), and ultimately to polypoidal choroidal vasculopathy (d). Eye tracked SD-OCT with ICGA at the PCV stage confirms the presence of nodular hypercyanescence on ICGA (yellow arrow; e) corresponding to the pigment epithelial detachment on SD-OCT (red arrow; e)
