Classification – Conforming vs Non-conforming: Previous authors2 have suggested sub-classifications of FCE, including those that exhibit conforming overlying neurosensory retinal layers and those that exhibit subretinal fluid and/or debris between the RPE/Bruchs and inner choroid within the choroidal excavation. It is not currently known whether each different subtype portends … [Read more...] about Case #71: Focal Choroidal Excavation: A Rare Sequela of Myopia? – Page 15 of 22

Discussion: Current literature describes FCE as an uncommon entity with unknown incidence or prevalence3. It is defined by a characteristic appearing isofocal or multifocal concavity or excavation of the inner choroid without underlying disruption to the sclera observed on OCT imaging but often times is not appreciated on clinical ophthalmoscopy4. It is most often observed … [Read more...] about Case #71: Focal Choroidal Excavation: A Rare Sequela of Myopia? – Page 11 of 22
