Diabetic Macular Ischemia Diagnosis: Comparison between Optical Coherence Tomography Angiography and Fluorescein Angiography

Figure 2

Diabetic macular ischemia (DMI) as seen on fluorescein angiography (FA) versus optical coherence tomography angiography (OCTA). Multimodal imaging of three different patients. Evaluation of foveal avascular zone (FAZ) extent on fluorescein angiography (a, b, and c) compared to optical coherence tomography (OCT) angiography. (d, e, and f) FAZ areas on both methods are represented by colored dotted lines. (g, h, and i) Semiautomatic segmentation of correspondent SD-OCT B-scan.
