“…Comparable result was reported in a hospital based study done by Rai S et al in Nepal, where 58% children were male. 1 Other hospital based studies done by Sethi MJ et al in Pakistan, Matta S et al in New Delhi also gave similar result. 4,5 In a population based study done by Dulani N et al in Jaipur, Rajasthan female preponderance was seen.…”

“…In the study done by Rai S et al 57% children with refractive errors were using spectacles at initial presentation. 1 Similarly 66.67% were already using glasses in study done by Dulani N et al 6 A possible reason for this difference may be lack of awareness or shyness to wearing spectacles in this area. Therefore, counseling of children and parents is of equal importance as that of diagnosing refractive errors and prescribing glasses.…”

“…Similar results were reported from Nepal, Ethiopia and Egypt. 1,10,16 Many studies done in several countries throughout the world including India reported myopia as the most common refractive error. 2,12 Use of different inclusion criteria can be one reason for such difference.…”

“…16 A study done in Lumbini Eye Institute, showed reported an entirely different scenario with astigmatism (47%) as the commonest type of refractive error followed by myopia (34%) and hyperopia (15%) among children. 20 Like wise a hospital-based study done in Kathmandu valley reported astigmatism (43.8 %) as the commonest error followed by hypermetropia (42.6%) and then myopia (13.6%). 21 In our study most common age group of myopia was 11-20 years and that of hypermetropia was after 30 years of age.…”

INTRODUCTION: Refractive error is one of the causes of avoidable blindness. Myopia, hypermetropia and astigmatism are the common types of refractive error. Not many studies are done to detect pattern of refractive error in Western Nepal. So, the study will determine the prevalence and distribution of refractive errors.MATERIALS AND METHODS: A prospective study of all consecutive patients of age less than 40 years who visited eye department, Gandaki Medical College, between May 2010 and May 2011 was conducted. Visual acuity, naked eye and pin hole examination was done by ophthalmic assistant with cycloplegic refraction when needed. Those who did not turn up for refraction were excluded from the study.RESULTS: A total of 601 patients were seen within the study period. Mean age of male patients was 22.4 years ±0.6 (95% CI, 21.2-23.6 years) and mean age of female patients was 24.2 years ±0.5 (95% CI, 23.2-25.2 years). Majority of the patients were in age group 11-20 years (39.3%). Myopia was the most common refractive error (43.3%) followed by simple myopic astigmatism (23.8%). Refractive errors were more common in females.CONCLUSIONS: Myopia was the commonest refractive compared to hypermetropia. Refractive error was more common in females than in males. Such studies help to know the picture of refractive errors in community and such reports are helpful in planning programme to prevent avoidable blindness

Among school children, uncorrected refractive errors have a considerable impact on their participation and learning in class. The aim of this study was to assess the prevalence of refractive error among students in the Ejisu-Juabeng Municipality of Ghana. A survey with multi-stage sampling was undertaken. We interviewed 504 students aged 12-17 years and examined them for refractive errors. The prevalence of refractive errors among those with and without refractive error was compared by means of the chi-square test. Logistic regression analysis using refractive error as the dependent variable and adjusting for risk factors were performed. The overall prevalence rate of refractive errors was 7.5%. Out of the number of children with refractive errors, 39.5% had astigmatism, 31.6% had hyperopia and 28.9% had myopia. The prevalence rate was significantly higher among urban compared with rural students. Astigmatic refractive errors consists of with-the-rule (WTR) astigmatism 66.7%, against-the-rule (ATR) astigmatism 26.7% and oblique astigmatism (OBL) 6.6%. WTR and ATR astigmatism were more common in females than males. Multivariate logistic regression models showed no substantial confounding effects between near work, sex, and residence, suggesting that each covariate has an independent association with refractive error. In conclusion, near work, sex and high parental education level are factors contributing to refractive errors. Children in urban areas are at higher risk compared with their rural counterparts. We suggest that an efficient pre-school vision examination must be made part of the admission policy of all schools in Ghana.

The distribution of refractive errors among children attending Lumbini Eye Institute, Nepal

Abstract: Astigmatism is the commonest type of refractive error among the children of age 5 - 15 years followed by hypermetropia and myopia. Refractive error remains uncorrected in a significant number of children.
