Choroidal structural analysis and vascularity index in retinal dystrophies [PDF]

Acta Ophthalmologica, 2018
AbstractPurposeTo assess choroidal structural changes in patients with retinal dystrophies using choroidal vascularity index (CVI), a novel optical coherence tomography (OCT) based tool.MethodsThis retrospective study included 26 patients with retinal dystrophies (17 with retinitis pigmentosa, four with Stargardt disease, three with cone‐rod dystrophy,

Choroidal vascularity index in adults with different refractive status

Photodiagnosis and Photodynamic Therapy, 2021
We aimed to perform structural analysis of the choroid in adults with different refractive status.A prospective, comparative study of 100 right eyes of 100 patients ages 18-40 years was conducted. The patients were divided into four groups according to spherical equivalent (SE): Group 1: -0.5 and above, low-to-moderate myopia; Group 2: -6 and above ...

Development and Retrospective Application of Novel Outcome Measure: Sturge–Weber Syndrome Acute Crisis (SWAC) Index

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Sturge–Weber syndrome (SWS) symptoms frequently overlap in neurological acute crises (ACs) presenting with seizures, stroke‐like episodes (SLE), and headaches. Recent efforts to develop a prospective drug trial highlighted the need for a new outcome measure capable of quantifying these symptoms during an SWS AC.

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

Impact of 1024‐Matrix Size on Perforating Artery Visualisation in Cerebral Computed Tomography Angiography Using a 64‐Slice CT Scanner

Journal of Medical Radiation Sciences, EarlyView.
This study investigated whether using a larger image matrix (1024 × 1024 pixels instead of 512 × 512) improves the visibility of tiny brain arteries on CT scans performed with standard 64‐slice scanners. While physical image quality measurements remained unchanged, the larger matrix provided finer digital sampling of blood vessel structures, resulting ...
