Indocyanine green angiography of pachychoroid pigment epitheliopathy

Purpose:
To compare choroidal hyperpermeability and vessel density between eyes with central serous chorioretinopathy (CSC), those with pachychoroid pigment epitheliopathy (PPE) and those with uncomplicated pachychoroid (UCP).
Methods:
We retrospectively reviewed indocyanine green angiography images of 60 patients with unilateral active CSC who had PPE (36 eyes) or UCP (24 eyes) in their fellow eyes. We used color thresholding of indocyanine green angiography images to determine choroidal vessel density.
Results:
The mean choroidal thickness of eyes with CSC was greater than that of eyes with PPE or UCP, but this difference was not statistically significant (P = 0.46). There was no significant difference between the PPE (92%) and CSC (93%) groups regarding choroidal hyperpermeability (P = 0.76), but both of these groups had higher choroidal permeability than the UCP group (50%) (both P
