METHODS: In this prospective cohort study, 40 eyes of 40 healthy volunteers underwent repeated OCTA (Cirrus HD-OCT 5000 angiography system, Carl Zeiss Meditec, Inc.) scans on two separate visit days. On each visit day, the eyes were scanned three times. The following parameters were used to quantitatively describe the OCTA images of the superficial vascular network: vessel area density (VAD), vessel skeleton density (VSD), vessel diameter index (VDI), vessel perimeter index (VPI), vessel complexity index (VCI), flux, and foveal avascular zone (FAZ). Coefficient of variation (CV) and intraclass correlation coefficient (ICC) were calculated for evaluating intravisit and intervisit repeatability, as well as interobserver reproducibility. RESULTS: The measurements showed high repeatability [CVs ⪕ 4.2% (intravisit) and ⪕ 4.6% (intervisit)] and interobserver reproducibility (ICCs ⪖ 0.923) for all parameters. CONCLUSION: This study demonstrated good repeatability and reproducibility of OCTA based on OMAG for the measurement of superficial vessel parameters in normal eyes.","is_dataset_classified":null,"base_score":3.8066624897703196,"endowment":3.8066624897703196,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"30025553","pmcid":null,"openalex_id":"https://openalex.org/W2889994594","authors":[],"funders":[],"total_grants":0,"fwci":3.6709,"citation_percentile":0.9283719,"influential_citations":0,"citation_trend":[{"year":2019,"count":3},{"year":2020,"count":6},{"year":2021,"count":8},{"year":2022,"count":7},{"year":2023,"count":9},{"year":2024,"count":7},{"year":2025,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubmed.ncbi.nlm.nih.gov/30025553","host_type":"repository"}],"fields_of_study":["Retinal Diseases and Treatments","Retinal Imaging and Analysis","Glaucoma and retinal disorders"],"mesh_terms":["Adult","Evaluation Studies as Topic","Female","Fluorescein Angiography","Humans","Image Processing, Computer-Assisted","Male","Middle Aged","Prospective Studies","Retina","Retinal Vessels","Reproducibility of Results","Cohort Studies","Tomography, Optical Coherence","Microvessels","Young Adult","Healthy Volunteers"],"keywords":["Repeatability","Reproducibility","Microangiography","Optical coherence tomography angiography","Intraclass correlation","Foveal avascular zone","Medicine","Optical coherence tomography","Coefficient of variation","Nuclear medicine","Ophthalmology","Anatomy","Mathematics","Macular Blood Flow","Retinal Superficial Capillary","Vascular Quantification"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-07T20:58:06.105383Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
