Pachychoroid disease is defined as: hyperpermeability on ICG angiography, loss if the inner choroid and dilated outer choroidal vessels (pachyvessels), presence of pachydrusen (drusenoid deposits) and diffuse or focal increased choroidal thickness visualized on OCT. The pachychoroid disease spectrum is divided in non‐neovascular pachychoroid disease and pachychoroid neovasculopathy (type 1 aneuvrysmal CNV, PCV). The non‐neovascular pachychoroid disease is divided in pachychoroid pigment epitheliopathy, central serous chorioretinopathy, peripapillary pachychoroid syndrome and focal choroidal excavation. The enhanced depth imaging module of the Spectral domain OCT (Heidelberg Inc ® ) allows measurement of the choroidal thickness and precise visualization of the different layers of the choroid thus guiding clinicians through differential diagnosis of pachychoroid disease and its related therapeutic management. At the end of the talk, participants should be able to recognizes key signs on EDI OCT of each subgroup of pachychoroid disease.
