Assessment of Refractive Status of 5-15 Years Old Children Attending Government Schools of Rural Agra

Abstract

Introduction: In children uncorrected refractive errors have a profound effect on educational and psychosocial development hence it is necessary to estimate the prevalence both at the community and at the school level to aid planning and implementation of refractive error services in children. Objective: To determine the refractive status of 5 to 15 years old children attending government schools of rural areas of district Agra, Uttar Pradesh (UP), India. Method: Study conducted on 902 students of age group 5-15 years of randomly selected government schools of Bichpuri Block of district Agra. Children underwent visual acuity assessment and torch light examination, height and weight measurement. Children with VA ≤6/9 were further examined and cycloplegic retinoscopy, fundus examination, slit lamp examination and post mydriatic refraction was done. On the basis of values of cycloplegic refraction and post mydriatic refraction, refractive error was classified as myopia, hypermetropia and astigmatism. Statistical Analysis was done by applying Chi square test. Result: Out of 902 children, 125 children (13.86 %) were having refractive error of which 76 were myopic (8.43%), 39 were astigmatic (4.32%) and 10 were hypermetropic (1.11%). There was an increase in the overall prevalence of refractive error with advancing age. There was no significant association of refractive error with gender and nutritional status. Conclusion: Vision screening of school children is very useful for early detection and correction of refractive errors. Screening of the refractive errors in school should be carried out periodically and regularly.
