Choroidal Structural Changes in Smokers Measured Using Choroidal Vascularity Index

Investigative Opthalmology & Visual Science, 2019
Cigarette smoking is a known risk factor for vascular dysfunction. This study evaluated choroidal structural changes in smokers using the choroidal vascularity index (CVI) derived from image binarization on spectral domain optical coherence tomography scans with enhanced depth imaging (EDI-OCT).This cross-sectional study included 39 smokers and 44 non ...

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

Eye (Lond), 2023
To determine changes in choroidal volume (CV) and choroidal vascularity index (CVI) in patients on hydroxychloroquine (HCQ) therapy.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 algorithm.
