This paper presents the results of analyzing the relation between visual acuity and developmental abilities (perceptive functions, verbal and non-verbal abilities) in younger school children. The sample consists of 1165 children from urban, suburban, and rural parts of Belgrade, of both genders, aged between 7.5 and 11. American 'Lighthouse' Optotype was used for screening assessment of visual acuity. Mild visual impairment, i.e. near visual acuity in the better eye ranging from 0.3 to 0.7, was detected in 7.9% of the pupils. ACADIA test of developmental abilities was used for the assessment of developmental abilities. When compared to the examinees with visual acuity in the better eye ranging from 0.3 to 0.7 (mild amblyopia), the examinees with normal visual acuity achieved better results in visuomotor coordination, non-verbal reasoning (Visual Association subtest), and concept formation in non-verbal domain (Sequence and Coding subtest). No significant differences were determined in constructive praxis (Drawing Shapes subtest) and representational dimension of a drawing (Drawing subtest). According to the criterion of age standard deviation, a statistically significant difference was determined between the examinees with mild visual impairment and the examinees with normal vision (χ2=13,425, df=2, p=0,001; ρ=0,103, p≤0,000). The results of 24.8% of the examinees with mild visual impairment deviate from age norms in one or two SD (14.9% in one SD, and 9.9% in two SD). In the group of examinees with normal vision 12.5% of the results deviate from age norms in one or two SD (8.7% in one SD, and 3.8% in two SD)
