    Eyelashes Artifact in Ultra-Widefield Optical Coherence Tomography Angiography

    BACKGROUND AND OBJECTIVE: To describe the presence of eyelashes artifact in ultra-widefield swept-source optical coherence tomography angiography (SS-OCTA) images. PATIENTS AND METHODS: In this prospective, cross-sectional study, 52 healthy, young subjects were imaged with the SS-OCTA system. OCTA scans were taken in primary and extremes of gaze, and a montage was automatically created. The en face choriocapillaris images were then exported, and a semi-automated algorithm was used for subsequent quantitative analysis. RESULTS: The authors noted the presence of some linear regions of reduced brightness, which were assumed to represent a shadow effect due to patient eyelashes. In order to quantify ...
