Background The global rising prevalence and incidence of multiple sclerosis (MS) has been reported during the past decades. However, details regarding evolution MS burden have not fully studied. This study aimed to investigate global, regional, national temporal trends in incidence, deaths, disability-adjusted life years (DALYs) from 1990 2019 using age-period-cohort analysis. Methods We performed a secondary comprehensive analysis DALYs by calculating estimated annual percentage change...
Aims To assess the global burden and economic inequalities in distribution of blindness vision loss between 1990 2019. Methods A secondary analysis Global Burden Diseases, Injuries Risk Factors Study (GBD) Data for disability-adjusted life-years (DALYs) due to were extracted from GBD gross domestic product per capita World Bank database. Slope index inequality (SII) concentration computed absolute relative cross-national health inequality, respectively. Results Countries with high,...
To explore the prevalence and risk factors for myopia uncorrected in schoolchildren southern China.The government-led Shantou Myopia Study was conducted from September 2020 to June 2021. Non-cycloplegic refraction performed. Uncorrected visual acuity (UCVA) measured along with presenting if participants wore spectacles. Spherical equivalent (SER) is defined as spherical dioptres added half of cylindrical dioptres. SER <-0.50 dioptre UCVA <20/20 at least one eye.This study enrolled 724 828...
This study aims to investigate the agreement between NK and KS formulas in predicting vault after implantation of an EVO-implantable collamer lens (ICL).
Objective: To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas and develop prognostic nomograms to predict risk postoperative refractive error in primary angle-closure glaucoma (PACG) patients. Methods: A total 111 eyes with PACG underwent goniosynechialysis combined phacoemulsification IOL implantation were included. SRK/T, Barrett II, Hoffer Q, Kane used refraction. Prediction (PE) absolute predictive (APE) produced by four calculated compared. An APE...
To compare the measurement accuracy of new/updated intraocular lens (IOL) power calculation methods, namely, Kane, Emmetropia Verifying Optical (EVO), with existing methods (Barrett Universal II, Olsen, Haigis, Hoffer Q, Holladay 1, SRK/T) in Chinese eyes axial lengths ≤ 22.5 mm.The study included data from patients who underwent uneventful cataract surgery insertion ZCB00 IOL. Refractive prediction errors were determined by calculating difference between postoperative refraction and...
To newly describe the vault measurement by using a widely used swept-source OCT-based optical biometer (IOLMaster700) and accessd accuracy of measurement.This was retrospective, cross-sectional study. All patients underwent implantable Collamer lens (ICL) implantation surgery without complications. IOLMaster700 AS-OCT analyses were conducted for each eye on same day in condition. Measurements anterior chamber depth (ACD), corneal-ICL (C-ICL), values made recorded. The repeatability IOL...
Objective To analyze and compare the temporal trends in incidence of anisometropia among Chinese school-aged children both before during COVID-19 pandemic, to investigate impact pandemic on anisometropia. Methods We conducted a retrospective study comprising six distinct independent longitudinal cohorts, each including aged 6 13 years who visited Joint Shantou International Eye Center between January 2010 December 2021. Children were grouped into cohorts based year their first eye clinic...
To investigate the association between children's school entrance age and refractive status prevalence of myopia in southern China. Population-based Cross-sectional study was conducted from September 2020 to June 2021 Shantou, China, enrolling primary schoolchildren city. The calculated as months birth date date, divided by 12. Non-cycloplegic refraction uncorrected visual acuity test were conducted. Myopia defined spherical equivalent (SER) < -0.50D with an distant Snellen 20/20. We...
Abstract Background The purpose of this study is to investigate the agreement NK and KS formulas in predicting vault after implantation EVO-implantable collamer lens (ICL). Methods In retrospective study, a total 106 eyes 59 patients who underwent ICL-V4c were included. predicted using formula was provided by anterior segment optical coherence tomography (AS-OCT) automatically. achieved measured AS-OCT at 1 month surgery. Multivariate linear regression analyses performed for evaluating...
Objectives To determine the progression and incidence of myopia in Chinese schoolchildren post-COVID-19 pandemic period Shantou, China. Design Prospective cohort study. Setting Shantou Myopia Study, Participants 1-year follow-up data were available for 621 881 (301 999 females). Data on spherical equivalent refraction (SER) collected. Primary secondary outcome measures The primary outcomes incidence. is defined as a change SER towards negative direction visit. Incidence proportion who not...
<sec> <title>BACKGROUND</title> Few research about the relationship between school entrance age and myopia in schoolchildren has been reported. </sec> <title>OBJECTIVE</title> To investigate association children's refractive status prevalence of southern China. <title>METHODS</title> This Population-based Cross-sectional study was conducted during September 2020 to June 2021 Shantou, China, enrolling all primary city.

Abstract Purpose To establish a machine learning (ML) model for predicting future spherical equivalent refraction (SER) and its annual progression rate in Chinese schoolchildren. Methods A total of 23,832 participants were analyzed, including 12,514 females 11,318 males. The follow-up visits conducted between February 2008 June 2021. SER value at specific time point was predicted based on the results least two cycloplegic measurements. prediction established using random forest (RF) model....
Abstract Objective To quantify age, period, and cohort effect on the global secular trend of prevalence blindness vision impairment (BVI) based age-period-cohort (APC) model. Methods Data BVI were extracted from Global Burden Diseases, Injuries, Risk Factors Study (GBD) 2019 database. Annual percentage change age-standardized rate (ASPR) was estimated by assuming a linear relationship between natural logarithm ASPR disease with time. The evaluated effects APC model intrinsic estimator....
Abstract Purpose: Hyperopic surprises tend to occur in axial myopic eyes and other factors including corneal curvature have rarely been analyzed cataract surgery, especially with long length (≥ 26.0 mm). Thus, the purpose of our study was evaluate influence keratometry on four different formulas (SRK/T, Barrett Universal II, Haigis Olsen) intraocular lens (IOL) power calculation for eyes. Methods: Retrospective case-series. 180 (AL) ≥ mm were divided into 3 (K) groups: K ≤ 42.0 D (Flat),...
Background: The detailed understanding of temporal trends myopia progression in school-age children is limited. We aimed to determine the patterns and between 2008 2018 Chinese children.Methods: consecutively collected refraction data from seeking cycloplegic refractions 2019. annual rate each child with at least 1 year follow-up was calculated. rates development were evaluated by Joinpoint regression model.
