 5. The investigator must confirm the presence of a PED on FAFP and OCT. Spectral Domain OCT will be utilized. Specifically, the Spectralis OCT manufactured by Heidleberg to maintain uniformity for all the sites. The PED height, SA, GLD, and volume will be measured from the OCT images. The characteristic OCT findings of the vascularized PED must be confirmed, including a distinct elevation of the highly hyperreflective RPE layer with mild backscattering of the underlying choroidal layer in the portion of the PED without any CNV. For the portion of the PED with underlying CNV, typical OCT findings consist of moderate hyperreflectivity contiguous to the overlying markedly hyperreflective detached RPE corresponding to the CNV that usually extends to the choroidal layer. Besides the OCT characteristics confirmation must be made on the FPFA images of the vascularized PED, as outlined above in detail.
