Eyes Is the Subject Area "Eyes" applicable to this article? Cost-effective strategies are needed to eliminate uncorrected refractive error as a cause of disabling visual impairment, particularly during the formative years of children.References1. Like wise prevalence of three government schools were 7% (30/429), 6.9% (28/413), 7.1% (22/308) respectively.Table 3Prevalence of refractive error by age and sexThe prevalence of refractive error was insignificantly different among Distribution of magnitude of myopia, hypermetropia and astigmatism was insignificantly different between male and female.Table 4.Magnitude of refractive error Type and magnitude of refractive error Total, n (%) Male, n (%) have a peek here

Forty-five (2%) students were amblyopic. The prevalence of high myopia of 13.9% in the 17-year-old children of our study was higher than in most previous children studies, and it was markedly higher than in the Beijing Copyright © 2011. The current cost of spectacle frames and lenses is often prohibitive in terms of creating access.

Prevalence Of Refractive Error In India

Sun J, Zhou J, Zhao P, Lian J, Zhu H, et al. (2012) High prevalence of myopia and high myopia in 5060 Chinese university students in Shanghai. At the age 5-7 years, mean score for hypermetropia was +1.8±1 (range, +1 to +4 D). Jyoti Jaggernath, 172 Umbilo Road, Durban, South Africa. Children with reduced vision and a sample of those with normal vision underwent independent replicate examinations for quality assurance in seven clusters.

Ellwein National Eye Institute, National Institutes of Health, Bethesda, Maryland. Astigmatism in either eye was present in 9.2% of children with retinoscopy, and in 14.6% with autorefraction. doi:  10.4103/0301-4738.100543PMCID: PMC3491271Uncorrected refractive errorsKovin S Naidoo1,2 and Jyoti Jaggernath21International Center for Eyecare Education, 172 Umbilo Road, Durban, South Africa2African Vision Research Institute, University of KwaZulu-Natal, Durban, South AfricaCorrespondence to: Dr. Nine of these children had bilateral hyperopia and two children were highly myopic in both eyes with a myopic refractive error of ≤−7.38 D and ≤−11.00 D in both eyes, respectively.

Similarly astigmatism less than 1.0 D and hypermetropia less than 1.5 D were common in 61.2% and 66.7% students.

The three core pillars to addressing the challenges posed by uncorrected REs relate to Human Resource (HR) Development, Service Development and Social Entrepreneurship.Human resource developmentHR Development remains the major challenge to http://supercgis.com/refractive-error/refractive-error-study-in-children-results-from-la-florida-chile.html Blindness and poverty: A tragic combination. Distribution of the refractive error (spherical equivalent) of right eyes, stratified by age and region of habitation, in the Shandong Children Eye Study. MethodsA cross-sectional study was designed to evaluate refractive status of 2236 school children in three government schools and a private school. Pubmed

Myopia range 2-6 D was most common (Table 4) in 48.8% followed by myopia less than 2 D in 41.9%. Unaided visual acuity was normal (6/6) in 2044 (91.4%) students. In addition, it contributes to poverty alleviation through job creation and local ownership. Check This Out The Baltimore Vision Screening Project.

Pokharel,J. Seventhly, we defined astigmatism as a cylindrical refractive error ≥0.75D in either eye. Contributed reagents/materials/analysis tools: HSB.

In left eyes, astigmatism was associated with older age (P = 0.034 and P = 0.012) but not with gender (P = 0.171 and P = 0.084).

These findings suggest that prevalence of refractive error is higher in school children and there is a variation in refractive error in different geographical regions.The prevalence of vision impairment was present Kishor Rijal, Ophthalmic Assistant, for helping during eye examination and data collection. Refraction was done using retinoscopy after 1% cyclopentolate eye drops had been instilled in the eyes at least half an hour previously. Se observó una agudeza visual espontánea, inicial y corregida inferior a 6/12 (0,5) en el 3,8%, 2,6% y 0,2% respectivamente.

Pupillary abnormalities were noted in 18 eyes of 15 (0.37%) children. Refractive error study in children in a rural population in India. World Health Organization.23. this contact form The marked increase in the prevalence of myopia, in particular of high myopia, in the young generation of China as compared to elderly population groups will be of importance for future

It is therefore necessary to consider the development of dedicated personnel for refraction and to conduct eye health screening.In many countries, the term ‘refractionist’ is used for those who have the Interestingly and in contrast to myopia, hyperopia overall was not significantly correlated with gender in our study. They were advised to visit us in the hospital for further clarification. Myopia was associated with older age (OR:1.56;95%CI:1.52,1.60;P<0.001), female gender (OR:1.22;95%CI:1.08,1.39;P = 0.002) and urban region (OR:2.88;95%CI:2.53,3.29;P<0.001).

After administration of a topical anesthetic (benoxinate 0.4%), cycloplegia was attained with 2 drops of 1% cyclopentolate (multidose applicator), administered 5 minutes apart, with a third drop administered after 20 minutes. Clustering effects were taken into account in the calculation of confidence intervals for prevalence estimates and in regression analyses. The distribution of mean spherical equivalent in the right eyes of boys and girls by cycloplegic retinoscopy is shown in Figure 1 . The 95% limits of agreement for cycloplegic autorefraction were −0.484 to +0.514 D and −0.425 to +0.436 D, respectively.  Results Study Population In the 35 study clusters, 6351 households were identified.

After refractive correction, visual acuity was significantly improved (χ2 = 81.3, df = 3, p < 0.01) to 6/6 in 98% students.
