Correlation Between Ischemic Retinal Accidents and Radial Peripapillary Capillaries in the Optic Nerve Using Optical Coherence Tomographic Angiograph…

2017

Background: Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, such as optical coherence tomographic angiography (Angio-OCT), is therefore important. Aim: A qualitative description is made of the vascular layers of the optic nerve and of how vascular events affect radial peripapillary capillaries (RPC). Two patients with central retinal artery occlusion (CRAO), …

Análisis cuantitativa, mediante OCT y Angio-OCT, del grosor coroideo y flujo vascular retiniano y su relación con la capa de fibras nerviosas y célul…

2021

El objetivo principal fue evaluar si existen cambios vasculares, en el grosor coroideo o en la densidad vascular macular, en pacientes con esclerosis múltiple (EM) respecto a controles sanos. Los objetivos secundarios fueron: determinar si existen diferencias vasculares basales según el grado de discapacidad; estudiar si los cambios vasculares se correlacionan con las diferencias de espesor de las capas de fibras nerviosas peripapilares (RNFLno), maculares (RNFLmac) y células ganglionares (GCL);analizar si a lo largo de un año existen cambios vasculares así como cambios anatómicos en los pacientes con EM;comparar el grosor coroideo y la densidad vascular entre pacientes con o sin presencia …
