Changes in Choroidal Vascularity Index (CVI) in Intermediate Uveitis

Translational Vision Science & Technology, 2021
To investigate the longitudinal changes in choroidal vascularity index (CVI) in eyes with active and quiescent intermediate uveitis using enhanced depth imaging optical coherence tomography (EDI-OCT).EDI-OCT images of eyes with active and quiescent intermediate uveitis were retrospectively reviewed and binarized using ImageJ software.

Choroidal Remodeling in Age-related Macular Degeneration and Polypoidal Choroidal Vasculopathy: A 12-month Prospective Study

Scientific Reports, 2017
Choroid thinning occurs in age-related macular degeneration (AMD). However, it remains unclear whether the reduction is due to reduction in choroidal vessels or shrinkage of choroidal stroma, or both. The purpose of this study was to evaluate the changes

Parkinson's Disease and Retinal Age Gap: A Cross‐Sectional Analysis

Movement Disorders, EarlyView.
Abstract Background Deep‐learning models are capable of predicting age from retinal scans and the difference between this and chronological age, retinal age gap, has been shown to be significantly associated with risk of mortality, cardiovascular diseases, and kidney failure.

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Hypertensive Disorders of Pregnancy and the Long‐Term Risk of Maternal Retinal and Ophthalmic Disease: A Systematic Review and Meta‐Analysis

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Hypertensive disorders of pregnancy (HDP) are associated with increased long‐term risk of maternal cardio‐metabolic disease, but links with future retinal diseases remain unclear. Objective The objective of this study is to synthesise the published literature on HDP and subsequent retinal and other ophthalmic disease.
