You QS, Guo Y, Wang J, et al. - Researchers conducted this prospective observational single-center study to assess wide-field optical coherence tomography angiography (OCTA) for detection of clinically unsuspected neovascularization (NV) in diabetic retinopathy (DR). Participants in the study were adult patients with a clinical diagnosis of nonproliferative DR. Study participants had a clinical examination, standard 7-field color photography, and OCTA with commercial and prototype swept-source devices. Photographic grading of 27 participants found 13 mild, 7 moderate, and 7 severe non-proliferative DR. Findings suggested that wide-field OCTA can detect tiny NV not seen on clinical examination or color photographs, and can improve DR clinical assessment.
