In this study, we implement an adaptive bidirectional interleaved scanning pattern for UWF-OCTA that enables the adjustment of\n                    <jats:italic>t<\/jats:italic>\n                    <jats:sub>inter<\/jats:sub>\n                    while keeping the scan area, sampling density, and total acquisition time constant or optimally tuned. We implemented this pattern on our high-speed (800 kHz\/1\u2005MHz) swept-source UWF-OCTA prototypes and assessed image quality across several use cases, including pediatric patients, non-human primates, and rodents. This protocol successfully captured detailed UWF-OCTA images with well-defined microvascular patterns. We observed that, while keeping sampling density and total scan acquisition time constant, a longer\n                    <jats:italic>t<\/jats:italic>\n                    <jats:sub>inter<\/jats:sub>\n                    enhances sensitivity to slower retinal blood flow, whereas a shorter\n                    <jats:italic>t<\/jats:italic>\n                    <jats:sub>inter<\/jats:sub>\n                    yields more robust, motion-resistant images with clearer choroidal vasculature, as supported by quantitative contrast-to-noise ratio analysis.
