Methods: A random sampling strategy in geographically defined clusters was used to identify children aged 6-15 years in Yongchuan, a socio-economically representative area in Western China. We carried out a door-to-door survey and actual eye examinations, including visual acuity measurements, stereopsis examination, anterior segment and eyeball movements, fundus examinations, and cycloplegic retinoscopy with 1% cyclopentolate. Results: A total of 3469 children living in 2552 households were selected, and 3070 were examined. The distributions of refractive status were positively-skewed for 6-8-year-olds, and negatively-skewed for 9-12 and 13-15-year-olds. The prevalence of hyperopia (≥+2.00 D spherical equivalent [SE]), myopia (≤-0.

MethodsA cross-sectional study was designed to evaluate refractive status of 2236 school children in three government schools and a private school. A complete eye examination was carried out refractive error in in all children including slit lamp examination, fundus examination, retinoscopy and subjective refraction. Chi-square test was performed to analyze incidence of refractive error in gender; age groups; type of schools. ResultsOut of 2236 students, refractive error was present in 192 (8.58%). Unaided, presenting, and corrected visual acuity less than 6/12 (0.5) were present in 3.8%, 2.6%, and 0.2% respectively. After refractive correction, visual acuity was significantly improved (χ2=81.3, df=3, p<0.01) to 6/6 in 98% students. Forty-five students (2.01%) were amblyopic. Refractive error was significantly prevalent (χ2=3.707, df=1, p=0.05, ODD=1.3) in male (9.76%) than in female students (7.48%). refractive error was significantly high in private school than government schools (χ2=6.7, df=1, p<0.01) Myopia was the most common type (44.79%) of refractive error. The myopia of 2-6 diopters was most common in

Among school children, it has a considerable impact on learning and academic achievement especially in under-served and under-resourced communities. There is a dearth of information about the magnitude of the problem in Ghana. A school based cross-sectional study was carried out to estimate the prevalence and distribution of refractive error among school children in the Cape Coast Municipality of Central Region of Ghana. A total of 1103 school children were enumerated out of which 961 underwent a full eye examination. The children were aged between five and 19 years (mean = 10.5 ± 3.4 years, 95% confidence interval [CI]: 10.3–10.7). Cycloplegic refraction was performed on each child who failed the reading test. Hyperopia was defined as spherical power of ≥+2.00 diopters sphere (DS), myopia as ≤-0.50 D and astigmatism as a cylindrical power of ≤-0.50 D. Of the children examined, only 0.6% had previously had an eye examination. The prevalence of low vision and blindness in the study population was 0.9% (95% CI: 0.881–0.919) and 0.1% (95% CI: 0.081&n
