    Error rate of automated choroidal segmentation using swept-source optical coherence tomography

    Purpose To investigate the error rate of automated choroidal segmentation and the effect of frame averaging on error rate. Methods A horizontal B scan at the fovea was performed in patients having various retinochoroidal disorders using swept-source optical coherence tomography (OCT) with frame-averaging technique. Scanned images were classified into four morphological groups: normal from fellow eyes (N F ), normal from pathologic eyes (N P ), retinal abnormality (R) and retinochoroidal abnormality (RC) group. Choroidal segmentation was automatically performed using built-in software of a swept-source OCT device, and the error rate of choroidal segmentation was analysed. Results Qualified images for all four ...
