Past and Present Terminology for the Retinal and Choroidal Structures in Optical Coherence Tomography

Abstract

Spectral domain optical coherence tomography (SD-OCT) is a non-invasive imaging method which is used in the diagnosis and followup of various macular diseases. SD-OCT provides detailed imaging of the retina. However, it has also been used to evaluate the choroidal layers. There are many publications on the OCT terminology, the definition and classification of retinal and choroidal structures including lines, bands and zones described in OCT. The aim of this review is to provide an overview of the literature on the past and present terminology for the retinal and choroidal structures seen in SD-OCT. To know OCT terminology will provide to be understanding better the pathogenesis of these diseases and the effects of therapeutic applications for these.
