Fluorescein Leakage and Optical Coherence Tomography Angiography Features of Microaneurysms in Diabetic Retinopathy

Figure 3

A typical diabetic microaneurysm with mild leakage on FA (yellow circle (a), early phase of FA (d), late phase of FA). The microaneurysm was visualized as comma-like type in OCTA en face image (yellow circle (b)). On OCT en face image, the microaneurysm appeared as a luminescent spot (yellow circle (c)). The microaneurysm was recognized an oval well-demarcated lesion on OCT B-scan (yellow circle (f)), and the flow proportion of the microaneurysm was 24.8% on OCT B-scan with flow overlay (yellow circle (e)).
