Purpose: Cigarette smoking is a known risk factor for vascular dysfunction. This study evaluated choroidal structural changes in smokers using the vascularity index (CVI) derived from image binarization on spectral domain optical coherence tomography scans with enhanced depth imaging (EDI-OCT). Methods: cross-sectional included 39 and 44 non-smokers. Choroidal images EDI-OCT were binarized into luminal area (LA) stromal (LA). CVI was calculated as ratio of LA to total choroid (TCA). CVI,...
Evaluate choroidal structural changes in preterm children with and without retinopathy of prematurity (ROP) using image binarization technique on swept-source optical coherence tomography (SS-OCT) scans.Prospective case-control study. Forty-one (79 eyes) aged 5-15 years a history birth 33 (63 age-matched full-term were recruited. Demographics including gestational age at birth, weight ROP documented. All subjects had undergone complete eye examinations, best-corrected visual acuity SS-OCT...
Purpose: To analyze choroidal angioarchitecture in sympathetic ophthalmia (SO) using swept-source optical coherence tomography (SS-OCT) images.Methods: Case-control study of six patients with SO. Qualitative changes and quantitative parameters, including thickness (CT) vascularity index (CVI), were analyzed.Results: findings the acute phase SO on SS-OCT included retinal serous detachment hyperreflective septa, folds, alterations loss vascular lacunae, Dalen-Fuchs nodules. There was...
Objective: To study the structural changes in choroid of diabetic patients following cataract surgery, using choroidal vascularity index and thickness. Methods: A prospective case–control was conducted 18 non-diabetic undergoing surgery (phacoemulsification) one eye. Enhanced depth imaging optical coherence tomography images were obtained before after surgery. Niblack’s image binarization performed to derive index. Independent sample T-test compared differences thickness between patients....
To assess the association between perinatal risk factors for retinopathy of prematurity (ROP) and central retinal structures former preterm children seen on optical coherence tomography angiography (OCTA).This prospective cohort study included 40 with a history birth 33 healthy full-term children. We documented their weight, gestational age, other significant ROP development presence ROP. Imaging was performed using swept-source OCTA, quantitative evaluation performed. Analytic parameters...
Background COVID-19’s infection control policies have hindered the Deliberate Practice of clinical examinations. Guided Mental Rehearsal (GMR) may overcome this obstacle by facilitating independent, repetitive practice. Underpinned ‘Motor Simulation Theory,’ GMR reinforces similar neuro-circuit activations during physical practice and was proven effective in surgical training.Methods This prospective, randomized controlled study evaluated efficacy versus ‘peer-learning’ Confrontational...
To explore the all-cause mortality in patients with acquired immune deficiency syndrome (AIDS) and Cytomegalovirus (CMV) retinitis.A retrospective cohort study of CMV retinitis (CMVR) presented to a tertiary referral center Singapore from January 1, 2004, through December 31, 2015.A total 144 were studied (87 survived, 11 lost follow up, 46 died). Patients bilateral CMVR six-month up CD4 + T cell count < 50 cells/mm3 have shorter time mortality, compared > (p .001) unilateral disease =...
To evaluate alterations in the choroidal angioarchitecture of COVID-19 patients using optical Coherence Tomography (OCT) based surrogate markers.This prospective case-control study recruited 56 (111 eyes) and 61 healthy individuals (120 eyes). Choroidal thickness (CT) vascularity index (CVI) were derived from OCT images a purpose-built automated software for image segmentation. A linear mixed model with age gender as covariates was employed to compare CVI CT between groups.COVID-19 had...
Digital village is an important task under the deployment of rural revitalization strategy, and inevitable requirement for building digital China. However, implementation mostly based on macro or regional perspective, neglecting assessment skills at micro level, which makes it difficult to judge effect strategy improvement routes comprehensively. Therefore, this paper takes elderly groups in Sichuan, Gansu Zhejiang provinces as research objects, constructs a framework by factor analysis...
