“…In case of any suspicion about flow impairment in the choriocapillaris in patients with macular lesions, flow images should be interpreted alongside structural en face images and OCT B scans. [67] SRF can affect the choriocapillaris OCTA signal. Swept-source OCT technology utilizes a longer wavelength and higher scan speed, therefore shadow artifacts are reduced with this generation of machines.…”

We performed a comprehensive search of the published literature in PubMed and Google Scholar to identify types, prevalence, etiology, clinical impact, and current methods for correction of various artifacts in optical coherence tomography angiography (OCTA) images. We found that the prevalence of OCTA image artifacts is fairly high. Artifacts associated with eye motion, misidentification of retinal layers, projections, and low optical coherence tomography signal are the most prevalent types. Artifacts in OCTA images are the major limitations of this diagnostic modality in clinical practice and identification of these artifacts and measures to mitigate them are essential for correct diagnosis and follow-up of patients.
