Semi‐automated detection of the foveal avascular zone in fluorescein angiograms in diabetes mellitus

Background:  The foveal avascular zone (FAZ) is known to enlarge in diabetic retinopathy. In a preliminary study, the authors applied a region growing algorithm to fluorescein angiograms to detect the FAZ in a semi‐automated fashion.
