Purpose Pathologic myopia described as myopia accompanied by severe deformation of the eye besides excessive elongation of eye, is usually a genetic heterogeneous disorder characterized by extreme, familial, early-onset vision loss. However, the exact pathogenesis of pathologic myopia remains unclear. In this study, we screened a Han Chinese family with pathologic myopia to identify the causati...

PURPOSE To determine the incidence and progression rates of myopia in young Singaporean children. METHODS A prospective cohort study, the Singapore Cohort Study of the Risk Factors for Myopia (SCORM), was conducted in two schools in Singapore (1999-2002). Children aged 7 to 9 years (n=981) were followed up over a 3-year period. Cycloplegic autorefraction and biometry parameter measures were p...

The mouse model has been widely employed to explore the mysteries of myopia. For now, existing techniques for induction of experimental myopia in mice can be classified into three types: (1) devices directly glued to the fur; (2) devices attached using a combination of glue and sutures; (3) devices attached using a skull-mounted apparatus. These techniques each have its advantages, disadvantage...

PURPOSE We investigated the association of genetic variations, which were identified recently in a large-scale genome-wide association study (GWAS) to confer risk of refractive error and common myopia in Caucasians, with high myopia in Japanese subjects. METHODS The 5 single-nucleotide polymorphisms (SNPs) from the 5 genes TOX, RDH5, ZIC2, RASGRF1, and SHISA6, were genotyped in 1339 unrelated...

Myopia has a multifactorial etiology, although environmental factors are predominant in determining its current patterns. Currently, associations between near work activities and myopia have not been consistently observed. Therefore, we performed a systematic review to quantify the effect of near work activities on myopia in children. Relevant articles published between 1989 and 2014 were ident...

Association studies have revealed that the rs1635529 polymorphism in the COL2A1 (collagen, type Ⅱ, α 1) gene may be a potential candidate for myopia development and may be associated with myopia in Caucasians. The aim of this study was to investigate the association of high myopia with 5 polymorphisms including rs1635529 in COL2A1 in a Chinese population. Genomic DNA samples were selected from ...

Myopia is the leading public health concern with high prevalence in developed countries. In this paper, we present the ACHIKO-M fundus image database with both myopic and emmetropic cases for high myopia study. The database contains 705 myopic subjects and 151 normal subjects with both left eye and right eye images for each subject. In addition, various clinical data is also available, allowing...

Background: Myopia, often known as near-sightedness, is a common visual issue that typically first appears between the ages of 6 and 14. Roughly 5% toddlers, 9% elementary schoolchildren, 30% high schoolers are affected. Having near-sighted parents increases child's risk developing myopia.
 Objective: To assess prevalence myopia among school students in urban area Bangladesh to explore ass...

TOPIC To evaluate the efficacy of interventions such as eyedrops, bifocal lenses, or contact lenses in retarding the progression of myopia in myopic children. CLINICAL RELEVANCE Myopia is a common ocular disorder, and high myopia (myopia at least -6.0 diopters) is associated with potentially blinding conditions. At present, there are no general guidelines on interventions that may decrease my...

PURPOSE To examine myopic progression and factors connected with myopic progression. METHODS Myopic schoolchildren, with no previous spectacles, 119 boys and 121 girls, were recruited during 1983-1984 to a randomized 3-year clinical trial of bifocal treatment of myopia with a subsequent 20-year follow-up. Participants' mean age at Baseline was 10.9, ranging from 8.7 to 12.8 years. An ophthalm...
