Holmen and coauthors determine the frequency of artifacts in optical coherence tomography angiography (OCTA) images and how these artifacts are identified. In a cross-sectional study that included 406 OCTA images of eyes with diabetic retinopathy, the prevalence of artifacts was 53.5%, with shadow, defocus, and movement seen as the most common artifacts. Proprietary quality indices commonly used for identifying unreliable images had a high sensitivity (99%) but low specificity (37% to 41%). The results of this study suggest that knowledge of OCTA artifacts may be important in accurately interpreting these images for patient care and in clinical trials.
