Choroidal vascularity index and thickness in sarcoidosis

Medicine, 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.

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.
