Choroidal Vascular Impairment in Intermediate Age-Related Macular Degeneration [PDF]

, 2022
Age-related macular degeneration (AMD) is a multifactorial disease, whose complete pathogenesis is still unclear. Local hemodynamics may play a crucial role in its manifestation and progression.

Ultrasonographic Assessment of Intrinsic Vascularity in Choroidal Nevus, Suspicious Choroidal Nevus, and Choroidal Melanoma

Ophthalmology Science
Purpose: To determine if intrinsic vascularity can be observed in B-scan ultrasound examinations of choroidal nevi (CN) and compare the intensity of the vascularity among CN, suspicious choroidal nevi (SN), and choroidal melanomas (CMs).

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Choroidal vascularity index and choroidal thickness: potential biomarkers in retinitis pigmentosa

Eye, 2022
AbstractRetinitis pigmentosa (RP) is the commonest inherited retinal dystrophy. It is characterized by progressive photoreceptor degeneration and cell death and ongoing neuronal and vascular impairment. In recent years, pathophysiological alterations of the choroid have begun to be appreciated in RP.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,
