    Progression of Diabetic Microaneurysms According to the Internal Reflectivity on Structural Optical Coherence Tomography and Visibility on Optical Coherence Tomography Angiography

    Purpose To investigate the progression of diabetic microaneurysms (MAs) according to the spectral-domain optical coherence tomography (SD-OCT) and OCT angiography (OCTA) characteristics and to evaluate their influence on the retinal extracellular fluid accumulation at 1 year follow-up in patients with nonproliferative diabetic retinopathy (NPDR). Design Prospective, observational case series. Methods Fourteen patients with NPDR underwent SD-OCT and OCTA at the baseline and at 1 year follow-up. For all the selected MAs the visibility, the changes of internal reflectivity, graded as hyporeflective, moderate, or hyperreflective, and the extracellular fluid accumulation surrounding each MA on SD-OCT at 1 year were evaluated. The ...
