    Association of Intravitreal Aflibercept With Optical Coherence Tomography Angiography Vessel Density in Patients With Proliferative Diabetic Retinopathy: A Secondary Analysis of a Randomized Clinical Trial

    Importance Although previous studies have evaluated the association between anti–vascular endothelial growth factor therapy and macular vessel density, they were confounded by the presence of macular edema, which may be associated with artifacts and segmentation errors in optical coherence tomography angiography (OCTA). Objective To evaluate the association of intravitreal aflibercept with changes in macular vascular density using OCTA in patients with proliferative diabetic retinopathy without diabetic macular edema. Design, Setting, and Participants This post hoc analysis of a randomized clinical trial used data on 40 eyes of 40 patients with proliferative diabetic retinopathy without diabetic macular edema who were ...
