Choroidal vascularity index and choroidal thickness assessment in vitiligo

Clinical and Experimental Optometry, 2023
Vitiligo is a skin disease characterised by depigmentation and loss of melanocytes. Melanocyte loss may not be limited to the skin in vitiligo, and various abnormalities may occur in the choroid, which is dense in melanocytes.To evaluate structural changes in the choroid by measuring choroidal thickness and vascularity index using optical coherence ...

Choroidal vascularity index in pseudoexfoliative glaucoma

International Ophthalmology, 2021
To evaluate choroidal vascular involvement in pseudoexfoliative glaucoma (PEXG) by applying the choroidal vascularity index (CVI) to optic coherence tomography (OCT) images.Seventy-eight eyes from 40 subjects were included the study. Group 1 included healthy eyes (n = 20), group 2 eyes with PEX (n = 16), and group 3 eyes with PEXG (n = 42). OCT imaging

Choroidal vascularity index in obstructive sleep apnea syndrome

Sleep and Breathing, 2021
There is growing evidence supporting an association between obstructive sleep apnea syndrome (OSAS) and systemic vascular disorders. However, the data on choroidal microvasculature are limited. In recent years, choroidal thickness (CT) and choroidal vascularity index (CVI) have been of considerable interest as objective markers of choroidal vascularity.

Exploring choroidal angioarchitecture in health and disease using choroidal vascularity index

Progress in Retinal and Eye Research, 2020
The choroid is one of the most vascularized structures of the human body and plays an irreplaceable role in nourishing photoreceptors. As such, choroidal dysfunction is implicated in a multitude of ocular diseases. Studying the choroid can lead to a better understanding of disease pathogenesis, progression and discovery of novel management strategies ...
