Increasing the number of spectral splits with respect to previous SSADA implementations [1,22] allowed increasing the flow signal-to-noise ratio (SNR) while maintaining the sharpness of capillaries in en face angiogram visualizations. The superficial vascular complex is demonstrated. Flow SNR increases from 5.6 for the 11 spectral splits (A, bandwidth of 27 nm, separated by 6.6 nm) to 9.5 for 18 spectral splits (B, bandwidth of 20 nm, separated by 4.3 nm) and 11.2 for 23 spectral splits (C, bandwidth of 18 nm, separated by 3.5 nm). Greater number of spectral splits did not yield further SNR improvement on en face OCTA projections.
