Abstract
Retinal pigment epithelial detachment (PED) is a feature of many chorioretinal disease processes, the most common of which is age-related macular degeneration. PED has different pathophysiology depending on the subtype, and may be associated with choroidal neovascularization. It shows a characteristic pattern in accordance with the imaging modality, but there is no clear differentiating method between its various subtypes. It is necessary to use multimodal imaging for evaluating PED. Optical coherence tomography (OCT) angiography, a new-developed imaging technique, is safe and convenient compared to conventional angiography, but it has narrow range of images and sometimes it does not get a clear image because of technical problems. Nevertheless, OCT angiography shows different images compared to prior imaging tools, so it will help understanding and diagnosing PED.
Key Words: Macular degeneration; Multimodal imaging; Optical coherence tomography angiography; Retinal pigment epithelium detachment
