AOSLO-Based Precise Measurement of Retinal Hemodynamics: Development and Application Assessment

Changes in retinal hemodynamics play a key role in the development of various eye diseases. Currently, mainstream hemodynamic evaluation techniques have low resolution and poor measurement accuracy, limiting their widespread application. Adaptive optical laser scanning ophthalmoscopy (AO-SLO) can capture retinal vascular images at the cellular level, offering the potential for high-precision retinal hemodynamic evaluation. This project will: ① innovate the AO-SLO blood flow imaging scanning module and acquisition mode, develop algorithms for extracting spatiotemporal signal features from blood flow images, and achieve quantitative analysis of retinal hemodynamics based on AO-SLO; ② construct an in vitro retinal hemodynamic measurement simulation eye, conduct multidimensional AO-SLO hemodynamic measurements, and establish an intelligent model for precise calibration of retinal hemodynamic parameters; ③ conduct AO-SLO-based retinal hemodynamic studies in high myopia, integrating multi-modal ophthalmic imaging to investigate the patterns of changes in retinal vascular structure and blood flow function in high myopia. Ultimately, a new precision measurement imaging technology platform for retinal hemodynamics will be established.
