Abstract

Purpose: To report the frequency of binocular motor anomalies & visual perceptual skills in normal school going children & special population Method: The study was carried out at Sarswati school, at Little Heart Special school & Nistha Special school New Delhi. Comprehensive eye examination, binocular vision assessment & visual perceptual skills with TVPS-R was carried out for 45 children in normal school & for 45 children at special schools. BV assessment was done for children with best corrected visual acuity of ≥6/9 :N6, cooperative for examination as well as free from any ocular pathologies Result: A total of 64% have normal binocular vision, 29% have AI (accommodative insufficiency). Majority 3% have CI (convergence insufficiency) and 5% have AI with CI in normal population as well as showed that among the participants the majority 51% have AI, 49% have CI in special population. Visual perceptual skills were 37(82%) have good visual perceptual skills and 8(18%) have poor visual perceptual skills in normal population and 22% have good visual perceptual skills and 78% have poor visual perceptual skills in special population. Comparison of binocular motor anomalies and visual perceptual skills in normal & special population shows p – value <0.001 (paired t- test). Conclusion: Non-strabismic binocular vision anomalies are highly prevalent among school children and the prevalence increases with age. With increasing near visual demands in the higher grades, these anomalies could significantly impact the reading efficiency of children. Thus, it is recommended that screening for anomalies of binocular vision should be integrated into the conventional vision screening protocol.
