INTRODUCTION

Amblyopia is one of the common causes of childhood visual impairment. The prevalence of amblyopia usually varies according to the age group of the studied population and the factors prevailing in that region. The upper limit of the critical time when amblyopia can develop is around eight years of age and it can be permanent if corrective measures are not taken in time.

AIM

The purpose of study was to know the profile and pattern of amblyopia in children aged 5-15 years with refractive error in Uttarakhand and to compare it with national and regional (South Asian) studies.

MATERIALS AND METHODS

In the present retrospective cross-sectional study, 360 children from 5-15 yrs of age who attended the OPD during the period between September 2014 to February 2015, had undergone detailed Ophthalmic examination.

The percentage of amblyopia was 8.6% (n=31) with insignificant gender variation (p-value>0.05). Amblyopia due to astigmatism (combined) was in 41.93% (n=13) followed by Hypermetropia [32.25% (n=10)] and least in myopia [25.8% (n=8)]. In 51.61% cases age of presentation was 5-10 years while rest belonged to > 10 years of age. Binocular amblyopia was more (58.06%) then unilateral amblyopia (41.93%).
