Li S, Lang X, Wang W, et al. - Among 142 patients and 20 normal control individuals, researchers assessed choroidal vascularity index (CVI) in eyes with internal carotid artery (ICA) stenosis using binarization tool in enhanced depth images scanned by spectral domain optical coherence tomography. According to this retrospective cohort study, no statistical difference was found in age or gender among groups. Mild stenosis, moderate stenosis, and severe stenosis proportions in CVI ≤ 65.16 group and CVI > 65.16% group were statistically significant. Findings suggested that CVI can be a useful indicator of early diagnosis and monitoring of ICA stenosis changes in choroidal vascular changes.
