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

Figure 2

A typical diabetic microaneurysm with no leakage seen by FA (yellow circle (a), early phase of FA (d), late phase of FA). The microaneurysm was not visualized in OCTA en face image (b). On OCT en face image, the microaneurysm appeared as luminescent ring-shaped morphology (c). The microaneurysm was recognized as an oval well-demarcated lesion on OCT B-scan (f), and the lumen was devoid of flow signal on OCT B-scan with flow overlay (e).
