Abstract

Background: School children are a high risk population for refractive errors (REs). Uncorrected REs can adversely affect the learning abilities and mental development of school children. Objectives: This cross sectional study was conducted to observe the proportion of cases diagnosed with REs, to determine factors associated with it, to find out the practices of students in preventing these risk factors and to assess the perception towards visual aids among students with REs in schools of an urban area. Methods: This study was done in Mangalore city in February 2013. 482 high school children were interviewed using a structured interview schedule. RE was ascertained based on records of previous diagnosis by Ophthalmologist. Data was analyzed by Chi-square test and binary logistic regression analysis. Results: The prevalence of already diagnosed cases of RE was 94(19.5%). Most of these cases had myopia 92(97.9%). Two cases were of hypermetropia. Mean age of onset of RE was 10.2±2.1 years. Only 19(20.2%) cases were first detected in schools in spite of functioning school health services at all the surveyed schools. RE cases were significantly more in private schools in comparison to government schools (P<0.001). Risk factors significantly associated with RE were history of RE among siblings (P<0.001), inadequate reading distance (P=0.011) and doing homework with inadequate illumination (P=0.021). One third of students with RE were irregular in eye examinations. Conclusion: Proportion of REs was high among school students. Education of students on healthy postural habits and good illumination while studying at home is essential to prevent REs in this population.
