Comparison of swept source optical coherence tomography (SS-OCT) and spectral domain optical coherence tomography (SD-OCT) in polypoidal choroidal vasculopathy
Background Swept source optical coherence tomography (SS-OCT, Topcon Medical System, Japan) is known to have longer wavelength than spectral domain OCT (SD-OCT, Spectralis, Heidelberg Engineering, Germany), allowing a deeper penetration into retina and choroidal layers. This objective of this study was to compare the visibility of retinal and choroidal features in polypoidal choroidal vasculopathy (PCV) using SS-OCT and SD-OCT. Design Prospective comparative observational case series in Singapore National Eye Center (SNEC) Participants There were 20 eyes (20 patients) with PCV confirmed with indocyanine green angiogram (ICGA). Methods Six pre-specified OCT parameters (presence of polyps, sharp pigment epithelial detachment (PED) peak ...
