Pachychoroid Pigment Epitheliopathy; Signs, Diagnosis, and Management

Pachychoroid (ancient Greek pachy: thick) means thick choroid. Pachychoroid pigment epitheliopathy (PPE) has been recently defined as forme fruste of central serous chorioretinopathy (CSC). Its characteristic findings are pachychoroid phenotype, a variety of RPE abnormalities, absence of subretinal fluid and absence of a history of subretinal fluid. PPE may progress to CSC or pachychoroid neovasculopathy. The aim of the current review is to provide an overview of signs, diagnosis, and management of PPE.
