Image analysis performed by the Erlangen‐Angio‐Tool. (a) Vessel densities were taken within the annular region of interest (inner ring diameter 0.80 mm, outer ring diameter 2.8 mm) for the macula optical coherence tomography angiography (OCTA) en face scan based on Hosari et al. 38 (b) To calculate the foveal avascular zone (FAZ) circularity and area, the perimeter of the FAZ was marked using a composite image of the three different retinal plexi present at the macula (depicted by different colours).
