Abstract

The aim of this study is to assess the prevalence of various ocular disorders among school going children in the age group of 5 to12 years.
Aim: Vision screening is crucial for early detection of ocular disorders among young children thereby preventing the risk of uncorrectable dimunition of vision. Hence, our programme is planned as early detection of the causative factors in the childhood period and most effectively treat as early as possible. The purpose of the screening programme is to identify various ocular diseases in children like refractive errors, amblyopia, defective color vision, lid and adnexal disorders, vitamin A deficiency, allergic conjuctivitis, glaucoma, cataract and squint. Identification of such problems and its correction in early stage is crucial for their normal growth.
Materials and Methods: A school based prospective cross sectional study design was adopted to examine children aged 5–12 years in randomly selected schools of Kollam district from January 2020 to March 2020.
In this cross-sectional study, two Optometrist and two Ophthalmologist and other supportive staffs screened 3100 school children aged 5 to 12 years for vision and external eye examination. An Optometrist did the visual acuity testing and refraction. Detailed ophthalmic examination was done by an Ophthalmologist.
The pattern of visual acuity, colour vision and ocular disorders were studied. Children needing further assessment were referred to the hospital and analysis of the data and data entry done using Microsoft office excel 2016 with Statistical software: R software (EZR 1.32).
Results: A total number of 3100 students from 11 different schools were examined, 1570 of whom were males, and 1530 were females. The commonest eye disorder was refractive error 16.6% (514) in which most common was myopic astigmatism 78.2% (402) of which 322 were against the rule and 80 were with the rule astigmatism, followed by simple myopia 15.2%(78) simple hypermetropia 4.7%(25) and hypermetropic
astigmatism 1.7%(9). Of these spectacles usage was found to be present only in 81.3% (418) students, rest 18.7%(96) were not aware of the refractive error. Next common eye disorder was allergic conjunctivitis 1.6%(49).
Squint was present in 1.4%(42) children. Corneal opacity was present in 0.26%(8), defective color vision was there in 0.2%(6); lids and adnexal disorders 0.13%(4) and cataract 0.03%(1). There were no students with congenital anomalies, congenital glaucoma or Vitamin A deficiency.
Conclusion: Uncorrected refractive error is the most common visual impairment found in school going children. There is a need to set up a regular school vision-screening programme to detect ocular disorders in order to prevent the burden on society on long term. Since most of this morbidity is either preventable or completely treatable, school screening is an effective method to reduce this burden.
