Pigment epithelial detachments in age related macular degeneration.

Pigment epithelial detachments (PEDs) form a heterogeneous group of lesions of diverse prognosis and treatment that have in common the pathologic elevation of the retinal pigment epithelium plane and its detachment from the underlying layers. Although PEDs are a common finding in age-related macular degeneration, especially in its exudative forms, the diagnostic characterization and prognostic estimation of these lesions is a clinical challenge that necessarily requires a multimodal imaging approach. This review presents the clinical characteristics of the different groups of PED, their diagnostic imaging profile, as well as their natural history.
