INTRODUCTION
Childhood ocular morbidity, of which refractive errors
form a significant fraction, is defined as a condition in the
study subject, recognized or suspected, ocular or vision
abnormality, which requires treatment or surveillance.

A
fact quoted by world health organization (WHO) that
“Every minute a child goes blind”, reflects the ever-
increasing global burden of childhood blindness. Even
though the proportion of infants and school aged children
with visual impairment is less than 5% worldwide, yet
they are included in bunch of 20% of individuals with
visual impairment after adjusting disability adjusted life
years (DALYs).

The available data is suggestive of the fact that the
difference in prevalence of childhood blindness between
the wealthiest and the poorest countries of the world may
be fifteen-fold, ranging from as low as around 0.3 per
1000 children aged 0-5 years in high economic nations to
1.5/1000 children in developing countries. If this very
correlation is used to estimate the prevalence of blindness
in children, the number of blind children in the world is
estimated to be 1.4 million. According to W.H.O.

ABSTRACT
Background: Uncorrected refractive errors are one of the major culprits of visual impairment among children in our
country. Children included in school going age groups i.e., 6-16 years, represent 25% of population in developing
countries. They fall in the category of preventable age group for correction of refractive errors. This paper describes
the salient features and results of the cross-sectional study conducted to determine the prevalence of refractive errors
and their association with socio demographic characteristics in pediatric population objective were to study the
prevalence of refractive errors and their association with socio demographic characteristics in pediatric patients
attending tertiary eye care centre.
Methods: The cross-sectional study was conducted for a period of one year among children in 0-16 years age group
and a total of 444 patients were included. All children were examined by ophthalmologists and refraction was done by
optometrists. Data was analysed using web-based software open epi version 3.01.
Results: Prevalence of refractive errors was found to be 29.5%. Amongst the socio demographic factors, there was a
significant association of age and literacy with refractive errors whereas gender and residence were not found to be
significant.
Conclusions: Refractive errors are an important preventable cause of childhood ocular morbidity. Schools are an
excellent platform to educate children and their parents regarding eye care and signs of ocular morbidity due to
refractive errors. Health education activities in schools need to be intensified.
