Additional file 4: Fig S4. Impact of correcting transverse magnification error in OCTA using ALact and ALest on OCTA image size and FAZA measurement. Correction of the OCTA image for the study participant with (a) a shorter eye in our cohort (AL = 21.45 mm) and (b) a longer eye (AL = 27.88 mm). ALact, actual axial length; ALest, estimated axial length; FAZA, foveal avascular zone area; OCTA, optical coherence tomography angiography.
