Choroid veins - Wikipedia
The choroid veins are the superior choroid vein, and the inferior choroid vein of the lateral ventricle. Both veins drain different parts of the choroid plexus.
Choroidal Vascular Anomalies: Posterior Vortex Veins ... - EyeWiki
This article reviews choroidal vascular anomalies, focusing on posterior vortex veins and varices, choroidal macrovessels, aneurysms, and submacular choroidal vessel varices. They can present with submacular choroidal elevation that mimics choroidal tumors, complicating diagnosis.
What Is Choroidal Neovascularization, How Is It Treated?
Apr 11, 2014 · Choroidal neovascularization (or CNV) is the growth of abnormal blood vessels beneath the retina. CNV can occur in a variety of conditions, and its effects are sometimes known as choroidal neovascular membranes (CNVM). Age-related macular degeneration is the most common condition CNV occurs with, but it is also seen with others.
Exploring the choroidal vascular labyrinth and its molecular and ...
Mar 1, 2022 · Venous blood from the choroid and other uveal tissues is returned via the vortex vein system, which originates in numerous small venules that converge to form choroidal veins.
What Are Macular Neovascular Membranes (MNV)?
Nov 20, 2023 · Macular neovascular membranes (MNV) are new, damaging blood vessels that grow inside or beneath the retina, in an area called the choroid. When these vessels leak clear fluid or bleed inside or under the retina they cause vision loss. MNV are associated with many serious eye diseases, most commonly wet age-related macular degeneration.
Choroidal Vein Alterations in Pachychoroid Disease With Choroidal ...
Pachychoroid disease (PCD)/pachychoroid spectrum disease are characterized by common morphological alterations in the choroidal structure, including choroidal thickening, dilation of choroidal vessels in Haller's layer, attenuation of the inner choroid, and choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA). 1 ...
The structure and function of the human choroid - ScienceDirect
Jun 1, 2024 · The choroid is a sponge-like vascular connective tissue located between the sclera and the retina and making up the posterior part of the uvea (Fig. 1). In humans, it is about 200 μm thick at birth and decreases to about 80 μm by age 90 years (Ramrattan et al., 1994).
CHOROIDAL BLOOD FLOW: Review and Potential Explanation for …
Purpose: To review control mechanisms for blood flow in the choroid, propose a system by which venous outflow is controlled by a Starling resistor, and propose an explanation for the choroidal venous architectural anatomy.
Vortex vein anastomosis and pachychoroid—an evolving …
Jan 29, 2021 · Vortex veins serve as choroidal drainage routes passing through the sclera. Horizontal and vertical watersheds divide the choroidal vasculature into four quadrants. Each quadrant is...
Choroidal Vein Alterations in Pachychoroid Disease With Choroidal ...
Aug 1, 2023 · Different patterns of ChV alterations, including the newly identified ChV confluence, are commonly present at CVH areas in PCD. The CVH areas in PCD eyes are primarily located within the dominant ChVs. These findings provide crucial evidence for advancing our understanding of the underlying mechanis ….
