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

Figure 4

A typical diabetic microaneurysm with severe leakage on FA (yellow circle (a), early phase of FA (d), late phase of FA). The microaneurysm was visualized as nodular 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 a thin-walled oval lesion on OCT B-scan with a retinal cyst nearby (yellow circle (f)), and the flow proportion of the microaneurysm was 57.8% on OCT B-scan with flow overlay (yellow circle (e)).
