Abstract

Methods: A total of 2741 children were included in study. The diagnostic endpoint for amblyopia was a best corrected visual acuity (BCVA) of <6/9 or 2-line inter-ocular optotype acuity difference. Chi-Square test was done for statistical analysis. Results: The prevalence of Refractive error & Amblyopia was 23.20%(n=636) & 3.39% (n=93) respectively. The average age of presentation was 11.58±2.78 years. The prevalence of refractive error due to astigmatism, myopia & Hypermetropia was 14.90,4.63, &3.61 % respectively. Maximum no of amblyopia was due to myopic astigmatism {58.06% (n=54)}, Hypermetropic astigmatism (n=24) followed by Myopia {8.60% (n=8]} and least in Hypermetropia {7.52%% (n=7)}. Binocular amblyopia was more (67%) then unilateral amblyopia (33%). Conclusion:As per the finding of our study, refractive error is a major risk factor for amblyopia therefore, it emphasizes the need for visual screening of young children and management of refractive amblyopia at appropriate time.
