      Reply to Correspondence: Impact of Binarization Thresholding and Brightness/Contrast Adjustment Methodology on Optical Coherence Tomography Angiography Image Quantification
      We thank Dr Rabiolo and associates for their interest in our work and their correspondence.1 We also applaud them for their valuable study that examined the effect of binarization thresholding on vessel area density (VAD) in retinal vascular optical coherence tomography angiography (OCTA) images.2 In their correspondence, they highlight several points regarding our results and conclusions compared with their own findings.

      Controlling for Artifacts in Widefield Optical Coherence Tomography Angiography Measurements of Non-Perfusion Area
      The recent clinical adoption of optical coherence tomography (OCT) angiography (OCTA) has enabled non-invasive, volumetric visualization of ocular vasculature at micron-scale resolutions. Initially limited to 3mm3mm and 6mm6mm fields-of-view (FOV), commercial OCTA systems now offer 12mm12mm, or larger, imaging fields. While larger FOVs promise a more complete visualization of retinal disease, they also introduce new challenges to the accurate and reliable interpretation of OCTA data. In particular, because of vignetting ...

      COmbined multimodal analysis of Peripheral Retinal and mAcular circulation in Diabetic Retinopathy (COPRA Study)
      Importance The relationship between peripheral retinal capillary non-perfusion with central NP is non-linear. Objective To systematically examine the relationships between the microvascular indices that are measured on OCTA and the presence and extent of peripheral non-perfusion in persons with diabetic retinopathy Design Retrospective cross-sectional study of patients with varying degrees of diabetic retinopathy ; Setting: Two large tertiary referral retina clinics Participants Eighty-two eyes of forty-five patients with varying degrees of ...

      Impact of Binarization Thresholding and Brightness/Contrast Adjustment Methodology on Optical Coherence Tomography Angiography Image Quantification
      Purpose Binarization is a critical technique in OCTA image analysis, but there is no consistency in the method used in published OCTA studies. This study assessed whether differences in OCTA binarization and brightness/contrast adjustments affect quantification metrics. Design Prospective cross-sectional validity study Methods This was a single-center study examining 21 eyes of 11 healthy individuals. All eyes were imaged using the Carl Zeiss PLEX Elite 9000 swept source-OCTA, and ...

      Early hydroxychloroquine retinopathy: optical coherence tomography abnormalities preceding Humphrey visual field defects
      Background/Aims Hydroxychloroquine (HCQ) retinopathy may result in severe and irreversible vision loss, emphasising the importance of screening and early detection. The purpose of this study is to report the novel finding of early optical coherence tomography (OCT) abnormalities due to HCQ toxicity that may develop in the setting of normal Humphrey visual field (HVF) testing. Methods Data from patients with chronic HCQ exposure was obtained from seven tertiary care ...
