Résumé
To characterize wide-field optical coherence tomography angiography (OCTA) features of retinal nonperfusion in eyes with branch retinal vein occlusion (BRVO). Automated scanning of five 12 × 12-mm areas of swept-source OCTA and wide-field fluorescein angiography (FA) images was performed in a consecutive case series of 27 eyes in 27 patients with BRVO in this institutional cross-sectional study. The correlation between the areas of retinal nonperfusion detected by both examinations was assessed. Panoramic images obtained in five 12 × 12-mm OCTA scans in eyes with retinal nonperfusion were binarized or skeletonized, and the associations between vascular parameters such as vascular density (VD) and vascular length (VL) with the wide-field FA characteristics were evaluated. The mean area of retinal nonperfusion in the OCTA images was 81.0 ± 66.8 mm OCTA images based on wide-field technologies can quantitatively evaluate retinal nonperfusion in eyes with BRVO.
