PURPOSE Assess prevalence of myopia and identify associated risk factors in urban school children. METHODS This was a cross-sectional study screening children for sub-normal vision and refractive errors in Delhi. Vision was tested by trained health workers using ETDRS charts. Risk factor questionnaire was filled for children with vision <6/9.5, wearing spectacles and for a subset (10%) of ran...

Purpose: Myopia is a refractive error of the eyes that causes blurred distance vision. Near work, genetics and environmental factors have been implicated as risk in Child myopia. This study seeks to determine association between time spent on outdoor play myopia among children Calabar, Nigeria.&#x0D; Methods: It was hospital-based case-control conducted 120 (5-17 years old) selected matched by ...

PURPOSE To assess prevalence and associated factors of myopia and high myopia in schoolchildren in Greater Beijing. METHODS The school-based, cross-sectional Greater Beijing School Children Myopia study was carried out in the year 2016 in 54 schools randomly selected from 15 districts in Beijing. Non-cycloplegic auto-refractometry of the right eyes was performed. RESULTS The study included ...

Myopia, a prevalent refractive error disorder worldwide, is characterized by the elongation of eye, leading to visual abnormalities. Understanding genetic factors involved in myopia crucial for developing therapeutic and preventive measures. Unfortunately, only limited number genes with well-defined functionality have been associated myopia. In this study, we found that homozygous TGM2-deleted ...

PURPOSE To map the gene(s) associated with autosomal dominant (AD) high-grade myopia. METHODS A multigeneration English/Canadian family with AD severe myopia was ascertained. Myopes were healthy, with no clinical evidence of syndromic disease, anterior segment abnormalities, or glaucoma. The family contained 22 participating members (12 affected). The average age of diagnosis of myopia was 8....

BACKGROUND Numerous syndromes with myopia and hearing loss have been described up to now. We present a family with pathologic myopia, corneal dystrophy, and deafness distinct from these syndromes. CASES Ten patients in the same Turkish family were evaluated by ophthalmologic, audiologic, physical, radiologic, genetic, serologic, and biochemical examinations. OBSERVATIONS Ophthalmic examinat...

OBJECTIVE To study the associations between near work, outdoor activity, and myopia among children attending secondary school in rural China. METHODS Among a random cluster sample of 1892 children in Xichang, China, subjects with an uncorrected acuity of 6/12 or less in either eye (n = 984) and a 25% sample of children with normal vision (n = 248) underwent measurement of refractive error. Su...

Purpose The crystallin beta A4 (CRYBA4) gene variant, rs2009066, was previously reported to be associated with high myopia in a southern Chinese population. In the present study, we investigated whether CRYBA4 variants were associated with high myopia in a Japanese population. Methods We recruited 1,063 Japanese patients with high myopia (spherical equivalent [SE] ≤-9.00 D in both eyes) and 1...

© 2016 Journal of ophthalmic and Vision research | published by Wolters KluWer medKnoW Sir, We read with great interest the article titled “Association between refractive errors and ocular biometry in Iranian adults” by Hashemi et al[1] The authors aimed to evaluate the association between refractive errors and ocular biometry. We appreciate their valuable study and would like to make a comment...
