Retinal structure and vessel density changes in cerebral small vessel disease

Frontiers in Neuroscience
BackgroundCerebral small vessel disease (CSVD) attaches people’s attention in recent years. In this study, we aim to explore retinal structure and vessel density changes in CSVD patients.MethodsWe collected information on retinal metrics assessed by ...

Vessel density mapping of small cerebral vessels on 3D high resolution black blood MRI

NeuroImage
Small cerebral blood vessels are largely inaccessible to existing clinical in vivo imaging technologies. This study aims to present a novel analysis pipeline for vessel density mapping of small cerebral blood vessels from high-resolution 3D black-blood ...

Relationship of Vessel Density to Vessel Length Density in Patients with Treated Fabry Disease

Diagnostics, 2023
Background: Fabry disease (FD) is a potentially lethal lysosomal disorder with systemic vascular changes. Previous studies demonstrated retinal vascular involvement using optical coherence tomography angiography (OCTA) in affected patients; Aim: To ...

Superficial capillary plexus vessel density/deep capillary plexus vessel density ratio in healthy eyes

BMC Ophthalmology, 2022
Background To identify factors differently affecting the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in healthy eyes using their vessel density (VD) ratio. Methods Healthy eyes were enrolled. The ratio between the VD of SCP and DCP

Peripapillary Vessel Density as Early Biomarker in Multiple Sclerosis [PDF]

Frontiers in Neurology, 2020
Background: To evaluate retinal vessel density (VD) in macular and in peripapillary regions in patients with recent onset of multiple sclerosis, at initial demyelinating event (IDE) and in matched relapsing-remitting multiple sclerosis (RRMS) patients. Methods: We evaluated VD in superficial capillary plexus, deep capillary plexus, choriocapillaris and

3D Retinal Vessel Density Mapping With OCT-Angiography

IEEE Journal of Biomedical and Health Informatics, 2020
Optical Coherence Tomography Angiography (OCTA) is a novel, non-invasive imaging modality of retinal capillaries at micron resolution. Recent studies have correlated macular OCTA vascular measures with retinal disease severity and supported their use as a diagnostic tool.

Retinal vessel density and cognitive function in healthy older adults. [PDF]

Exp Brain Res
Abstract The eye is considered a gateway to the brain, as the retina is the only tissue of the central nervous system not protected by bones. This enables non-invasive imaging to provide exceptional insights into the brain. Based on the similarity of brain and retinal structure, it is being investigated whether changes in retinal blood flow ...
