Retinal Vasculature in Development and Diseases - PMC
Schematic diagram of the ocular vasculature. (a) Cross-sectional image of an eye.(b) An enlarged cross-sectional view of the retinal and choroidal vasculature.Three interconnected layers of retinal vessels are embedded among inner retinal neurons: The superficial retinal vasculature lies in the NFL; the intermediate and deep retinal vascular networks lie along each side of the INL.
Retinal Vascularization and OCT-Angiography Interpretation
Optical Coherence Tomography Angiography (OCT-A) is a non-invasive imaging modality that allows a detailed and three-dimensional study of retinal and choroidal vessels. This article discusses the anatomy of normal retinal vasculature and its analysis by OCT-A.
Detailed Vascular Anatomy of the Human Retina by Projection …
2017年2月10日 · By demonstrating the anatomic organization of the retinal vascular plexuses in normal human eyes, this work using PR-OCTA provides a rational schema for nomenclature and segmentation of the retinal vasculature in future OCTA publications.
Imaging the Retinal Vasculature - PMC - National Center for ...
2021年9月9日 · Advances in retinal Imaging are enabling researchers and clinicians to make precise noninvasive measurements of the retinal vasculature in vivo. This includes capillary blood flow and regulation and oximetry as well as the complete mapping of perfused blood vessels.
Simple Anatomy of the Retina - Webvision - NCBI Bookshelf
2005年5月1日 · The retina is approximately 0.5 mm thick and lines the back of the eye. The optic nerve contains the ganglion cell axons running to the brain and, additionally, incoming blood vessels that open into the retina to vascularize the retinal layers and neurons (Fig. 2).
Retinal vasculature development in health and disease
Development of the retinal vasculature is based on highly coordinated signalling between different cell types of the retina, integrating internal metabolic requirements with external influences such as the supply of oxygen and nutrients.
A Revised View on Growth and Remodeling in the Retinal Vasculature
2019年3月1日 · The uttermost part of the retina, including the photoreceptor layer is nourished by the choroidal vasculature, whereas superficial layers of the retina are supplied by the inner retinal...
Functional Anatomy, Fine Structure and Basic Pathology of the Retinal …
The retinal circulation, which supplies the inner retina, is observed ophthalmoscopically as a regular geometrically arranged network of vessels and their three-dimensional complexity reflects the cellular density of the retinal neuropile.
Recognizing Abnormal Vasculature - Review of Optometry
2017年1月15日 · Examining the arteriolar-venular caliber ratio can assist in diagnosing vascular abnormalities and associated pathology. A reduced ratio could indicate retinal venular dilation, arteriolar attenuation or both. Fundus photography can help monitor any changes in retinal vasculature and retinopathy.
