PURPOSE Two previous genome-wide association studies (GWAS) of high myopia in a Japanese population found several single nucleotide polymorphisms (SNPs) associated with the disease. The present study examined whether these markers are associated with myopia in a Chinese population. METHODS Individuals with or without complex myopia were recruited from Chinese university students, and probands...

PURPOSE To report the frequency of adult-onset myopia in a large cohort of Caucasian twins that were assessed as part of the Genes in Myopia (GEM) twin study and to quantify the genetic contribution in adult-onset myopia using the classic twin model. METHODS All twins aged 18 years or older were invited to participate in the GEM twin study through the Australian Twin Registry (ATR). Each twin...

Highlights:1. The selection of delivery methods in pregnant patients with myopia is needed to prevent blindness.2. Although there was no report retinal detachment either spontaneous or cesarean section this study, all pathologic peripheral degeneration should be consulted by Ophthalmologist. AbstractIntroduction: blindness. This study aimed calculate and prevalence myopia.Methods: a descriptive...

PURPOSE Examine the prevalence of myopia and high myopia, at 6 and 9 months postterm and 2 and 3 years postnatal in preterm children with birth weights < 1251 g who developed high-risk prethreshold retinopathy of prematurity (ROP) in the neonatal period and participated in the Early Treatment for ROP Study. DESIGN Randomized controlled clinical trial. PARTICIPANTS Four hundred one infants w...

OBJECTIVE To compare the prevalence and risk factors for myopia in 6- and 7-year-old children of Chinese ethnicity in Sydney and Singapore. METHODS Two cross-sectional samples of age- and ethnicity-matched primary school children participated: 124 from the Sydney Myopia Study and 628 from the Singapore Cohort Study on the Risk Factors for Myopia. Cycloplegic autorefraction was used to determi...

PURPOSE To determine the changing prevalence of myopia during the years 1990 through 2002 among the 16- to 22-year age group and identify possible risk factors. METHODS A retrospective study, based on 13 repeated prevalence surveys conducted over a 13-year period. The study subjects were all Israeli nationals belonging to the 16- to 22-year age group from the years 1990 to 2002. Refraction wa...

CASE REPORT A 34-year-old man with severe myopia, presented with acute visual loss in his right eye. This occurred 3 hours after a posterior chamber phakic (PCP) intraocular lens (IOL) implantation, and was associated with a rhegmatogenous retinal detachment. Retinal retachment surgery was performed without complications, with the outcome showing good anatomical and functional results during a ...

The aim of this review was to quantify the global variation in childhood myopia prevalence over time taking account of demographic and study design factors. A systematic review identified population-based surveys with estimates of childhood myopia prevalence published by February 2015. Multilevel binomial logistic regression of log odds of myopia was used to examine the association with age, ge...

PURPOSE We explored risk factors for myopia in 12- to 13-year-old children in Northern Ireland (NI). METHODS Stratified random sampling was performed to obtain representation of schools and children. Cycloplegia was achieved using cyclopentolate hydrochloride 1%. Distance autorefraction was measured using the Shin-Nippon SRW-5000 device. Height and weight were measured. Parents and children c...
