Abstract
BACKGROUND: School children are affected by various eye disorders like refractive errors, squint, Vitamin A deficiency and eye infections. Most children do not complain of defective vision, as they may not recognize such conditions as a problem. Uncorrected refractive errors form the primary cause for visual impairment and blindness in India. This warrants early detection and treatment of these problems to prevent future blindness. OBJECTIVES: The study was conducted with the Primary objective of estimating the prevalence of ocular morbidity among the school going children (6-12 yrs) and the secondary objective is to assess its associated factors and the major ocular morbidity among them. MATERIALS AND METHODS: This was a cross sectional study conducted in randomly selected six schools of rural Kallur Block in Tirunelveli District in Tamilnadu. The students were screened for eye disorders by visual acuity testing, anterior segment torch light examination and fundus examination with undilated pupil. Visual Acuity assessed with Snellen’s or ‘E ‘chart at a distance of 6 meters. Color vision was tested on Ishihara chart. Convergence test and test for Squint were carried out. Children with vision not improving with pinhole screened for refractive errors. Cycloplegic Refraction done. RESULTS: A total of 500 children were examined. The prevalence of ocular morbidity was 15.4%. Refractive error was the commonest morbidity (63.6%) and Blepharitis was the Second most common ocular morbidity followed by conjunctivitis (9.3%), Stye (5.2%), squint (4.1%) of total ocular morbidities. Other lesser common conditions like vitamin A deficiency, corneal opacity, ocular trauma, ptosis, amblyopia accounted for 1.3% each in total ocular morbidity. CONCLUSION: The results of the study strongly suggest that refractive errors, especially myopia being the most common ocular morbidity among the school going children. Prevalence of refractive error was significantly higher with increasing age, positive parental history of refractive error, watching television, playing mobile games for more than two hours. Ocular disorders among school going children can be easily identified by regular eye screening programmes, and screened for undetected Refractive error, which needs early detection and treatment with corrective spectacles to prevent further progression of refractive error and preventing ambylopia in children, thereby childhood blindness can be prevented. The eye health awareness among children and school teachers should be improved.
