75-year-old man with large central drusen noted clinically. There are 3 main types of PEDs: a) drusenoid, b) serous, and c) vascularized. The presence of opaque material below the pigment epithelium is useful to distinguish a Drusenoid PED from a Serous PED (which would be relatively empty on OCT). A Vascularized PED is a true choroidal neovascular membrane (CNV). Typical findings include variable reflectivity below the PED along with intraretinal fluid, subretinal fluid and blood, clinically.
