Choroidal vascularity index and thickness in sarcoidosis. [PDF]

Medicine (Baltimore), 2022
Abstract Sarcoidosis is a multisystem granulomatous disease which is observed worldwide. Sarcoidosis is one of the common causes of ocular inflammation. The choroidal vascularity index, defined as the ratio of the luminal area to the total choroidal area, is used as one of the biomarkers for assessing the choroid vascular state.

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 and choroidal thickness: potential biomarkers in retinitis pigmentosa [PDF]

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.

Impact of Brightness on Choroidal Vascularity Index. [PDF]

J Clin Med
The use of choroidal vascularization to diagnose and follow-up ocular and systemic pathologies has been consolidated in recent research. Unfortunately, the choroidal parameters can be different depending on the lighting settings of optical coherence tomography (OCT) images.

Effects of hydroxychloroquine therapy on choroidal volume and choroidal vascularity index. [PDF]

Eye (Lond), 2023
Purpose: To determine changes in choroidal volume (CV) and choroidal vascularity index (CVI) in patients on hydroxychloroquine (HCQ) therapy. Methods: Retrospective analysis of patients on HCQ therapy. CV and CVI were assessed below the central foveal region on spectral-domain optical coherence tomography using an automatic denoising and localization ...
