Subretinal Drusenoid Deposits AKA Pseudodrusen

A distinction between conventional drusen and pseudodrusen was first made in 1990, and more recently knowledge of pseudodrusen, more accurately called subretinal drusenoid deposits (SDD), has expanded. Pseudodrusen have a bluish-white appearance by biomicroscopy and color fundus photography. Using optical coherence tomography, pseudodrusen were found to be accumulations of material internal to the retinal pigment epithelium (RPE) that could extend internally through the ellipsoid zone. These deposits are more commonly seen in older eyes with thinner choroids.
