A Novel Automatic Method to Estimate Visual Acuity and Analyze the Retinal Vasculature in Retinal Vein Occlusion Using Swept Source Optical Coherence Tomography Angiography
Díez Sotelo, Marta; Díaz González, Macarena; Abraldes, Maximino; Gómez-Ulla, Francisco; Penedo, Manuel; Ortega Hortas, Marcos (MDPI AG, 2019-09-20)[Abstract] The assessment of vascular biomarkers and their correlation with visual acuity is one of the most important issues in the diagnosis and follow-up of retinal vein occlusions (RVOs). The high workloads of clinical ... -
Automatic extraction of vascularity measurements using OCT-A images
Díaz González, Macarena; Novo Buján, Jorge; Penedo, Manuel; Ortega Hortas, Marcos (Elsevier, 2018)[Absctract]: Optical Coherence Tomography Angiography (OCT-A) represents a new modality of ophthalmological imaging that stands out for being a non-invasive capture technique that facilitates the analysis of the vascular ... -
Automatic segmentation of the foveal avascular zone in ophthalmological OCT-A images
Díaz González, Macarena; Novo Buján, Jorge; Cutrín, Paula; Gómez-Ulla, Francisco; Penedo, Manuel; Ortega Hortas, Marcos (Public Library of Science, 2019-02-22)[Abstract]: Angiography by Optical Coherence Tomography (OCT-A) is a non-invasive retinal imaging modality of recent appearance that allows the visualization of the vascular structure at predefined depths based on the ... -
Automatic Visual Acuity Estimation by Means of Computational Vascularity Biomarkers Using Oct Angiographies
Díaz González, Macarena; Diez Sotelo, Marta; Gómez-Ulla, Francisco; Novo Buján, Jorge; Penedo, Manuel; Ortega Hortas, Marcos (M D P I AG, 2019-10-31)[Abstract] Optical Coherence Tomography Angiography (OCTA) constitutes a new non-invasive ophthalmic image modality that allows the precise visualization of the micro-retinal vascularity that is commonly used to analyze ... -
Automatic Wide Field Registration and Mosaicking of OCTA Images Using Vascularity Information
Díaz González, Macarena; Moura, Joaquim de; Novo Buján, Jorge; Ortega Hortas, Marcos (Elsevier BV, 2019)[Abstract] Optical Coherence Tomography Angiography (OCTA) constitutes a novel ophthalmological image modality that is characterized for being a non-invasive capture technique that allows a profound analysis of the vascular ... -
Diabetic Macular Edema Characterization and Visualization Using Optical Coherence Tomography Images
Vidal, Plácido; Moura, Joaquim de; Díaz González, Macarena; Novo Buján, Jorge; Ortega Hortas, Marcos (MDPI AG, 2020-10-31)[Abstract] Diabetic Retinopathy and Diabetic Macular Edema (DME) represent one of the main causes of blindness in developed countries. They are characterized by fluid deposits in the retinal layers, causing a progressive ... -
Fully Automatic Method for the Visual Acuity Estimation Using OCT Angiographies
Díaz González, Macarena; Novo Buján, Jorge; Penedo, Manuel; Ortega Hortas, Marcos (MDPI AG, 2020-09-04)[Abstract] In this work we propose the automatic estimation of the visual acuity of patients with retinal vein occlusion using Optical Coherence Tomography by Angiography (OCTA) images. To do this, we first extract the ... -
Modeling, Localization, and Segmentation of the Foveal Avascular Zone on Retinal OCT-Angiography Images
Carmona, Enrique J.; Díaz González, Macarena; Novo Buján, Jorge; Ortega Hortas, Marcos (IEEE, 2020-08-17)[Absctract]: The Foveal Avascular Zone (FAZ) is a capillary-free area that is placed inside the macula and its morphology and size represent important biomarkers to detect different ocular pathologies such as diabetic ...
