AbstractStudies have reported that refractive errors are associated with premature births. As twins have higher prevalence of prematurity than singletons, it is important to assess similarity of the prevalence of refractive errors in twins and singletons for proper interpretations and generalizations of the findings from twin studies. We compared refractive errors and diopter hours between 561 pairs of twins and 3757 singletons who are representative of school-age children (7–15 years) residing in an urban area of southern China. We found that the means and variances of the continuous measurement of spherical equivalent refractive error and diopter hours were not significantly different between twins and singletons. Although the prevalence of myopia was comparable between twins and singletons, that of hyperopia and astigmatism was slightly but significantly higher in twins than in singletons. These results are inconsistent with those of adult studies that showed no differences in refractive errors between twins and singletons. Given that the sample size of twins is relatively small and that this study is the first to demonstrate minor differences in refractive errors between twins and singletons, future replications are necessary to determine whether the slightly higher prevalence of refractive errors in twins than in singletons found in this study was due to a sampling error or to the developmental delay often observed in twins in childhood.

Abstract: The incidence of uncorrected refractive errors is high in school-age children. If this condition is not treated seriously, it will have a negative impact on the development of children's intelligence and learning process which in turn will affect the quality, creativity, and productivity of work. This study was aimed to determine the refractive errors in students at SMA Negeri 7 (Senior High School) Manado. This study used a cross sectional design and was conducted from November to December 2015. Respondents were 25 students at grades 12th of SMA Negeri 7 Manado who had refractive errors obtained by using total sampling method. Visual acuity was assessed by using Snellen chart. The results showed that of all respondents, 72% were females and 28% were males. Based on the types of refractive errors, 72% had myopia and 28% had myopia associated with astigmatism. Most of the subjects (52%) were 17 years old. As many as 64% of respondents had family history of refractive errors. Respondents who performed near-sight activity were 96%; most of the activities was watching the television.Keywords: refractive error, risk factor, near-sight activity, school-age children Abstrak: Angka kejadian kelainan refraksi yang tak terkoreksi cukup tinggi pada anak usia sekolah. Jika kondisi ini tidak ditangani sungguh-sungguh akan berdampak negatif pada perkembangan kecerdasan anak dan proses pembelajaran yang selanjutnya akan memengaruhi mutu, kreativitas, dan produktivitas kerja. Penelitian ini bertujuan untuk mengetahui gambaran kelainan refraksi pada pelajar di SMA Negeri 7 Manado. Penelitian ini menggunakan desain potong lintang dan dilaksanakan pada bulan November-Desember 2015. Responden ialah 25 siswa/i kelas XII SMA Negeri 7 Manado yang mengalami kelainan refraksi, diperoleh dengan metode total sampling. Pengambilan data dilakukan dengan pemeriksaan visus menggunakan Snellen chart dan kuesioner. Hasil penelitian mendapatkan dari seluruh responden didapatkan 72% berjenis kelamin perempuan dan 28% berjenis kelamin laki-laki. Berdasarkan jenis kelainan refraksi didapatkan 72% menderita kelainan refraksi miopia. Sebagian besar responden berusia 17 tahun (52%). Sebanyak 64% penderita memiliki riwayat keluarga inti dengan kelainan refraksi. Responden yang melakukan aktivitas melihat jarak dekat dan lama sebanyak 96% dan aktivitas yang paling banyak dilakukan ialah menonton televisi. Kata kunci: kelainan refraksi, faktor resiko, aktivitas melihat jarak dekat, anak usia sekolah

Background: Refractive errors are common eye disorders and are leading causes of visual impairment in the general population. Children with uncorrected refractive error may experience reduced visual acuity, transient blurring, headache and persistent ocular discomforts particularly for close work which can impair reading efficiency and school performance.Aim: This article documents the prevalence of refractive errors in school-age children of different ethnic origins. The goal is to identify possible variation in measuring techniques and diagnostic criteria, as well as limitations of studies, to provide a clear direction for future studies.Methods: The review was undertaken through a detailed evaluation of peer-reviewed publications of primary research on this topic. The keywords for the search included ‘refractive error’, ‘hyperopia’, ‘myopia’, ‘astigmatism’ and ‘school children’. Only epidemiological studies with participants between 5 and 18 years of age were included.Results: Although several population and school-based studies have been conducted in various racial groups and populations, their findings were diverse owing to inconsistencies in the methods applied in identifying children in need of refraction, measurement techniques and diagnostic criteria for refractive errors. There are also some limitations associated with the sampling design and characteristics, which may have influenced the outcome measures.Conclusion: Despite the problems inherent in the studies, the review indicates that refractive error in school-age children is a public health concern in those populations and warrants additional research that will provide reliable data for proper planning of intervention strategies.
