Abstract

BACKGROUND AND OBJECTIVE: Optical coherence tomography angiography (OCTA) is a non-invasive technique to visualize changes in retinal microvasculature. The relationship between the retinal blood flow and systemic diseases can be studied using biomarkers extracted from the OCTA en-face images. However, these images are prone to various artifacts that can hinder the image quality. Thus, image qualit…
