    Correspondence: Impact of Binarization Thresholding and Brightness/Contrast Adjustment Methodology on Optical Coherence Tomography Angiography Image Quantification

    We read with interest the article by Mehta and colleagues titled “Impact of Binarization Thresholding and Brightness/Contrast Adjustment Methodology on Optical Coherence Tomography Angiography Image Quantification.” 1 The authors tested 5 methods to binarize optical coherence tomography angiography (OCT-A) en face angiocubes at the superficial capillary plexus (SCP) and choriocapillaris (CC) on a small cohort of healthy subjects. They found significant differences among the methods for the parameters studied, and the differences were more pronounced at the CC level.
