Myopia is the most common cause of visual impairment in children and young adults. In order to assess the consequences for society, it is necessary to know temporal trends in prevalence, incidence and...
High myopia is a leading cause of blindness worldwide. However, the exact etiology and mechanism of high myopia remain unclear. Previous genome-wide association study has demonstrated that nine single...
Seven SNPs were genotyped by the MassARRAY iPLEX Gold method in a Han Chinese cohort with the majority from Henan region (central China), which included 361 patients with high myopia and 749 healthy c...
In terms of genotyped SNPs, the allele frequency of rs698047 locus of the HIVEP3 gene were statistically different between myopia and control groups initially, but the difference disappeared after Bon...
There was no demonstrated association between the occurrence of high myopia in the Chinese Han population and polymorphisms in the following loci: HIVEP3 (rs698047), NFASC/CNTN2 (rs2246661), ZC3H11B (...
To explore the association between two single-nucleotide polymorphisms (SNPs) in the SOX2 gene and high and extreme myopia in the Han Chinese population....
A genetic association study using a case-control method was performed with 139 high myopia, 318 extreme myopia, and 918 healthy participants from the Chinese Han population. Two SNPs (rs4459940 and rs...
The mean ages of the extreme myopia and control subjects were 47.44 ± 15.59 and 44.15 ± 14.08 years, respectively. The rs4575941 SNP of the SOX2 gene and the GG and AG genotypes showed no significant ...
The SOX2 rs4575941 polymorphism, in Chinese Han population, contributes to the susceptibility of extreme myopia. SOX2 may thus be implicated in extreme myopia rather than in high myopia....
To explore the prevalence and risk factors for myopia and uncorrected myopia in schoolchildren in southern China....
The government-led Shantou Myopia Study was conducted from September 2020 to June 2021. Non-cycloplegic refraction was performed. Uncorrected visual acuity (UCVA) was measured along with presenting vi...
This study enrolled 724 828 schoolchildren (77.8% of all schoolchildren in Shantou) from 901 schools. Data from 721 032 schoolchildren (99.5%) were analysed (mean age 11.53±3.13 years, 6-20 years, 373...
The overall prevalence of myopia among schoolchildren in Shantou was 51.8%, higher than the national average in China. The proportion of uncorrected myopia is high, especially in primary schools. Our ...
Intraocular lens implantation in phakic eyes for the correction of refractive error is currently a widespread procedure. The EVO and EVO+ Visian Implantable Collamer Lenses (ICL) are two of the most p...
During the last decade, more than 100 scientific papers analyzing the performance of EVO and EVO+ lenses have been published. This review describes the objective visual performance achieved with the i...
Refractive surgeons and candidates to undergo ICL implantation should be aware of the excellent safety and visual outcomes provided by the implantation of central hole ICL lenses. However, future rese...
Initial studies have suggested that multiple segment (MS) spectacle lenses can reduce the progression rate of childhood myopia and axial eye growth. This paper aimed to compare the effectiveness of tw...
Published data from the only two clinical trials in which changes in mean spherical equivalent refraction (SER) and axial length (AL) for matched groups of myopic children wearing either MS or single-...
Absolute changes in SER and AL differed over time during the two trials. However, if the results were expressed in terms of efficacy over successive 6-month periods, then the two MS lenses produced br...
Myopia control may be due to either the additional myopic defocus induced by the MS lenses (i.e., asymmetry of the through-focus image changes about the distance focus) or to the general reduction in ...
Multiple segment spectacle lenses offer a valuable new approach to the control of myopia progression in children. Further work is required to clarify their mechanism of action and to optimise their de...
This study is a retrospective analysis to compare ocular biometry measurements of axial length in children with myopia using Myopia Master (OCULUS, Wetzlar, Germany) and Lenstar LS900 (HAAG-STREIT AG,...
Axial length measurements obtained with both instruments within a 3-week period were collected retrospectively. Measurements were visualized with a Bland-Altman plot. For statistical evaluation, a pai...
Sixty-one eyes from 31 myopic patients (59% male, 41% female) with a mean age of 11.34 ± 3.25 years (range: 6 - 18 years) were identified. Mean axial length was 24.7 mm (SD 1.29) with the Myopia Maste...
The axial length measured by Myopia Master and Lenstar LS900 did not differ significantly. Thus, previous values obtained with the Lenstar LS900 can be applied to assess myopia progression....
The META-Analysis of Pathologic Myopia Study group proposed a new classification system for myopic maculopathy (MM) with pathologic myopia (PM) defined as MM equal to/more serious than diffuse atrophy...
This study examined the optical impact of a DF contact lens during near viewing in a sample of habitual DF lens wearing children....
Seventeen myopic children aged 14 to 18 years who had completed 3 or 6 years of treatment with a DF contact lens (MiSight 1 Day; CooperVision, Inc., San Ramon, CA) were recruited and fit bilaterally w...
During near viewing, children wearing single-vision lenses accommodated on average to achieve approximate focus in the pupil center but, because of combined accommodative lag and negative spherical ab...
The DF contact lens did not alter the accommodative behavior of children. The treatment optics introduced myopic defocus and decreased the amount of hyperopically defocused light in the retinal image....
The rising prevalence of myopia among children and adolescents necessitates effective interventions to mitigate long-term risks, such as retinal detachment and macular degeneration. Traditional approa...
