PREVALENCE OF REFRACTIVE ERRORS AMONG SECONDARY SCHOOL CHILDREN IN AN URBAN SETUP: A PROSPECTIVE AND OBSERVATIONAL STUDY
Keywords:Prevalance, Refractive errors, Myopia, Hypermetropia, Astigmatism, Urban School Children
Objective: The aim of the study was to determine the prevalence of refractive errors and their types by their age, sex, and class among the students of secondary school in an urban area of state of Punjab, North India.
Methods: A cross-sectional study was done on a total of 1545 school children, aged between 10 and 16 years studying in 6th–10th class. Sample size included 822 males and 723 females. Snellen’s distant test types and self-illuminated streak retinoscope were used for this study.
Results: Cumulative prevalence of refractive errors was found to be 35.21% among the students. The distribution among the type of refractive errors was: Myopia – 65.07%, Hypermetropia – 14.89%, and Astigmatism – 20.04%. The prevalence among the male and female students was 34.91% and 35.55%, respectively.
Conclusion: This study supports the screening of school children for visual acuity and their refractive errors so that they can be identified to improve their quality of life at present and also to prevent any long-term visual disability.
