Theoretical baseline FAZ (tbFAZ) detection for patients with significant DME. A1-A3: the foveal region was partially affected by cystic fluid. A1: cross-sectional B-scan with cystic fluid (yellow dash line). A2: maximum projection en face image of inner retinal angiogram overlaid with fluid cysts (white region). A3: the final tbFAZ (yellow region) was defined as the intersection of the fitted circle (magenta curve) and angiographic FAZ (cyan curve). B1-B3: The foveal region was totally affected by cystic fluid. B1: cross-sectional B-scan with cystic fluid (yellow dash line). B2: maximum projection en face image of inner retinal angiogram overlaid with fluid cysts (white region). B3: the final tbFAZ (yellow region) was defined as the maximum inscribed circle of angiographic FAZ (cyan curve).
