Abstract
Aim: To assess the quality of vision screening done by trained schoolteachers on schoolchildren.
Method: This study was carried out in Greater Hyderabad by selecting 10 schools in 3 different clusters by
means of systematic random sampling. Teachers were imparted training for detecting vision defects and important
ocular conditions and were permitted to screen the students using a protocol ascribed to them. Students who were
screened by teachers were rescreened by optometrist to compare and analyse the outcome of the training imparted.
Results: A total of 25 schoolteachers were trained and utilized for screening 600 students in age ranging from 8
to 13 (mean is 10.5 and ±SD is 1.87) girls constituting 55%. The impact of training increased knowledge level to
88%. Similarity found in detection of children with poor visual acuity <6/9 by both ‘the trained teachers and
optometrist. Significant eye conditions which required early intervention were detected with the help of signs and
symptoms learnt through the training (Kappa statistic=0.95) suggesting an excellent agreement among the teachers
and optometrist.
Conclusion: The study results suggest that trained teachers can be relied upon for screening children to identify
various eye conditions including refractive errors. This study recommends incorporating a module on vision
screening in the teachers’ education curriculum and conducting screening in schools on a regular basis.

Introduction
A global initiative was launched by the World Health Organization
in 1999 to eliminate avoidable blindness by the year 2020 [1].
Childhood blindness is one of the top priorities in this program as
blind children contribute more cumulative blind years than adults who
become blind later in life. Approximately, 500,000 children become
blind every year and 70 million blind person years are added each year
due to childhood blindness [2]. In India alone there are 270,000 blind
children i.e. constituting approximately 19.0% of the blind population
[3]. Visual disabilities in children including the Childhood Blindness
should be addressed through a comprehensive program approach [4].
A recent study examined 6,935 children and estimated that the
prevalence of childhood blindness was 0.17% (95% confidence interval
0.09 to 0.30) of which treatable refractive error caused 33.3%, followed
by 16.6% preventable causes in which 8.3% due to vitamin A
deficiency and 8.3% due to amblyopia after cataract surgery [5]. Such
reports reveal that 50% of blindness is avoidable [6]. Most of the
children population in India [7] is in rural areas where awareness on
the conditions causing avoidable childhood blindness is relatively
unknown [8]. Educating parents and teachers with adequate
knowledge on these conditions would help in preventing the causes of
visual impairment, early detection and early intervention of these
conditions.
A comprehensive eye health program was conducted for school
going children supported by Lions Clubs International and Johnson
and Johnson Vision Care Sight for Kids undertaken by L V Prasad
Eye Institute and Lions Partner eye facilities in Greater Hyderabad.
This program is focused on the children studying in Government and
Government aided primary and upper-primary schools in the
underserved locations of Greater Hyderabad. In the process of
screening, schoolteachers were utilized for detecting eye problems
among the children after imparting a concise training. This study
wanted to analyse the effectiveness of teachers involvement in
detecting children through preliminary screening in the pursuit of
examining every child in the school and appropriately referring for
addressing each and every eye condition; simple to complex.
Henceforth, a qualified optometrist and teachers who were fresh to
this kind of program have been utilized in this study. This study
reports the effectiveness of teachers training which reduces the time of
ophthalmic personnel in early detection and accessibility for up-taking
eye care services by children belonging to marginalized sector
communities.
