Reproducibility of Choroidal Thickness Measurements Across Three Spectral Domain Optical Coherence Tomography Systems
Purpose: To investigate the reproducibility of choroidal thickness measurements in normal subjects on 3 spectral domain optical coherence tomography (SD-OCT) instruments: Zeiss Cirrus HD-OCT (Carl Zeiss Meditec Inc., Dublin, CA), Heidelberg Spectralis (Heidelberg Engineering, Heidelberg, Germany), and Optovue RTVue (Optovue Inc., Fremont, CA).Design: Cross-sectional non-interventional study.Participants: Images were obtained in 28 eyes of 28 healthy undilated volunteers without ocular pathology in a clinical setting.Methods: All subjects were imaged on the fovea using Cirrus HD 1-line raster, Spectralis enhanced depth imaging (EDI), and RTVue retina-cross.Main Outcome Measures: The choroid was measured subfoveally, 750 μm temporal, and 750 ...
