Given that there are many systemic and eye diseases that affect the eye fundus and its vascularity, the analysis of that region is crucial to diagnose and estimate the vision loss. The Visual Acuity (VA) is typically measured manually, implying an exhaustive and time-consuming procedure. In this work, we propose a method that exploits the information of the OCTA images to automatically estimate the VA with an accurate error of 0.1713.<\/jats:p>","DOI":"10.3390\/s19214732","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T06:33:29Z","timestamp":1572503609000},"page":"4732","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Automatic Visual Acuity Estimation by Means of Computational Vascularity Biomarkers Using Oct Angiographies"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6904-2968","authenticated-orcid":false,"given":"Macarena","family":"D\u00edaz","sequence":"first","affiliation":[{"name":"Grupo VARPA, Instituto de Investigaci\u00f3n Biom\u00e9dica de A Coru\u00f1a (INIBIC), Universidade da Coru\u00f1a, 15006 A Coru\u00f1a, Spain"},{"name":"Centro de Investigaci\u00f3n CITIC, Universidade da Coru\u00f1a, 15071 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4247-0417","authenticated-orcid":false,"given":"Marta","family":"D\u00edez-Sotelo","sequence":"additional","affiliation":[{"name":"Complejo Hospitalario Universitario de Santiago, 15706 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"G\u00f3mez-Ulla","sequence":"additional","affiliation":[{"name":"Complejo Hospitalario Universitario de Santiago, 15706 Santiago de Compostela, Spain"},{"name":"Instituto Oftalmol\u00f3gico G\u00f3mez-Ulla, 15706 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0125-3064","authenticated-orcid":false,"given":"Jorge","family":"Novo","sequence":"additional","affiliation":[{"name":"Grupo VARPA, Instituto de Investigaci\u00f3n Biom\u00e9dica de A Coru\u00f1a (INIBIC), Universidade da Coru\u00f1a, 15006 A Coru\u00f1a, Spain"},{"name":"Centro de Investigaci\u00f3n CITIC, Universidade da Coru\u00f1a, 15071 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel Francisco G.","family":"Penedo","sequence":"additional","affiliation":[{"name":"Grupo VARPA, Instituto de Investigaci\u00f3n Biom\u00e9dica de A Coru\u00f1a (INIBIC), Universidade da Coru\u00f1a, 15006 A Coru\u00f1a, Spain"},{"name":"Centro de Investigaci\u00f3n CITIC, Universidade da Coru\u00f1a, 15071 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2798-0788","authenticated-orcid":false,"given":"Marcos","family":"Ortega","sequence":"additional","affiliation":[{"name":"Grupo VARPA, Instituto de Investigaci\u00f3n Biom\u00e9dica de A Coru\u00f1a (INIBIC), Universidade da Coru\u00f1a, 15006 A Coru\u00f1a, Spain"},{"name":"Centro de Investigaci\u00f3n CITIC, Universidade da Coru\u00f1a, 15071 A Coru\u00f1a, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1016\/j.cmpb.2016.10.019","article-title":"Hydra: A web-based system for cardiovascular analysis, diagnosis and treatment","volume":"139","author":"Novo","year":"2017","journal-title":"Comput.
