Abstract :

INTRODUCTION: Amblyopia has been defined in a variety of ways. Von Graefe, defined amblyopia as the condition in which the observer sees nothing and patient very little1. Clinically amblyopia has been defined as unilateral or bilateral reduction in the best-corrected visual acuity caused by form vision deprivation and /or abnormal binocular interaction, without a visible organic cause commensurate with this visual loss2.<o:p></o:p> MATERIAL AND METHODS:A prospective study was undertaken from Dec 2012 to May 2014 at Govt schools of GVMC, Vizag. Total 8436 school going children aged between 5-15 years were screened and children whose VA < 6/12 and not improving with pin hole were included in the study. These children with poor vision were referred to Govt. REH and further examination for amblyopia was done.<o:p></o:p> <o:p> </o:p> RESULTS:This study was to identify the various factors influencing the prevalence of amblyopia.The study was conducted in 15 schools and a total of 8436 children were screened and 106 Children were diagnosed  Amblyopic.<o:p></o:p> <o:p> </o:p> CONCLUSION:Amblyopia is more common in the age group of 11-13 yrs( 34%) , with more prevalence in boys (54%) than girls. Anisometropic amblyopia is the commonest type of amblyopia (29%).In amblyopia caused by refractive errors, hypermetropia( 65%) is common than Myopia(35%).Children  even with a hypermetropia of 2-4 D developed amblyopia in majority of cases(48%) where as myopia of >6 D was responsible for amblyopia in large no. of cases (54%). Esodeviation was responsible for amblyopia than exodeviation in more no. of cases (68%).Initiation of treatment in children with amblyopia before 8 years of age yields a better prognosis.<o:p></o:p>
