Characterization of Diabetic Microaneurysms by Simultaneous Fluorescein Angiography and Spectral-Domain Optical Coherence Tomography

Simultaneous FA and SD-OCT allows detailed characterization of perfused diabetic microaneurysms. Increased FA leakage of diabetic microaneurysms positively correlated with perianeurysm fluid and retinal thickness. Perfused microaneurysms seen by SD-OCT were localized deeper than the inner nuclear layer.
