Refractive Error In School Children In India


In 103 (2.6%) children, acuity was 20/40 or worse in both eyes, including 7 (0.18%) children who were blind, with acuity less than 20/200 in the better eye. ResultsOut of 2236 students, refractive error was present in 192 (8.58%). Villages with an estimated population of less than 700 were combined with other small village(s), whereas those with populations of more than 1450 were subdivided, to create 248 clusters. Jialiang (2000)4 in 12.8% in China, Trivedi (2006)11 in 2.7% in Gujrat, and Pokhrel (2000) in 1.62% in Jhapa. have a peek here

Emmetropia (Figure 1) was observed in 1762 (78.8%) whereas hypermetropia around + 0.5 D after cycloplegic refraction was observed in 282 students (12.6%).Figure 1Distribution of refractive error in school children.At the age of Reproducibility of visual acuity measurements, objective refraction, and autorefraction was assessed between the two ophthalmic technicians during the pilot.  The survey was approved by the Ethics Committee of the L. Refractive error was prevalent in 9.8% (106/1086) male and 7.5% (86/1150) female. http://www.ncbi.nlm.nih.gov/pubmed/11867575

Uncorrected visual acuity of 20/32 or better in at least one eye was found in 3885 (97.3%), corresponding to 109 (2.7%) with acuity of 20/40 or worse in both eyes (Table 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%).

The findings in this survey are comparable with the ones obtained in the current study.  From a public health perspective, vision screening is an appropriate strategy to reduce vision impairment. Description of prevalence of refractive error was also different in our study from Pokhrel report. Children who could not keep the scheduled date were given another date within the same week or were offered an examination near the end of the study. http://supercgis.com/refractive-error/refractive-error-in-school-children.html There is an apparent need for parental as well as school education programs along with effective strategies for providing school-based vision screening, quality optometric services, and provision of providing affordable spectacles.Conflict
