{"doi":"10.1117/1.nph.11.4.045003","title":"In vivo volumetric analysis of retinal vascular hemodynamics in mice with spatio-temporal optical coherence tomography","abstract":"Significance: Microcirculation and neurovascular coupling are important parameters to study in neurological and neuro-ophthalmic conditions. As the retina shares many similarities with the cerebral cortex and is optically accessible, a special focus is directed to assessing the chorioretinal structure, microvasculature, and hemodynamics of mice, a vital animal model for vision and neuroscience research. Aim: volumetric mouse retinal monitoring of vascular hemodynamics with high temporal resolution. Approach: We translated the spatio-temporal optical coherence tomography (STOC-T) technique into the field of small animal imaging by designing a new optical system that could compensate for the mouse eye refractive error. We also developed post-processing algorithms, notably for the assessment of (i) localized hemodynamics from the analysis of pulse wave-induced Doppler artifact modulation and (ii) retinal tissue displacement from phase-sensitive measurements. Results: images of the retinal and choroidal structure and microvasculature from various layers, after digital aberration correction. We were able to measure the pulse wave velocity in capillaries of the outer plexiform layer with a mean speed of 0.35 mm/s and identified venous and arterial pulsation frequency and phase delay. We quantified the modulation amplitudes of tissue displacement near major vessels (with peaks of 150 nm), potentially carrying information about the biomechanical properties of the retinal layers involved. Last, we identified the delays between retinal displacements due to the passing of venous and arterial pulse waves. Conclusions: The developed STOC-T system provides insights into the hemodynamics of the mouse retina and choroid that could be beneficial in the study of neurovascular coupling and vasculature and flow speed anomalies in neurological and neuro-ophthalmic conditions.","journal":"Neurophotonics","year":2024,"id":458528,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":5,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9554,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1284814,"name":"Wiktor Kulesza","orcid":"0009-0007-8122-7977","position":1,"is_corresponding":false},{"id":1285333,"name":"Maciej Wielgo","orcid":null,"position":2,"is_corresponding":false},{"id":681614,"name":"Slawomir Tomczewski","orcid":"0000-0001-7938-2088","position":3,"is_corresponding":false},{"id":1284815,"name":"Anna Galińska","orcid":"0000-0003-4570-0425","position":4,"is_corresponding":false},{"id":1285334,"name":"Bartłomiej Bałamut","orcid":null,"position":5,"is_corresponding":false},{"id":1088648,"name":"Katarzyna Kordecka","orcid":"0000-0002-4425-8009","position":6,"is_corresponding":false},{"id":1284816,"name":"Onur Cetinkaya","orcid":"0000-0002-0965-1980","position":7,"is_corresponding":false},{"id":254239,"name":"Andrzej T.
