Abstract

PURPOSE. In an investigation of the functional impact of amblyopia in children, the fine motor skills of amblyopes and agematched control subjects were compared. The influence of visual factors that might predict any decrement in fine motor skills was also explored.--- METHODS. Vision and fine motor skills were tested in a group of children (n 82; mean age, 8.2 1.7 [SD] years) with amblyopia of different causes (infantile esotropia, n 17; acquired strabismus, n 28; anisometropia, n 15; mixed, n 13; and deprivation n 9), and age-matched control children (n 37; age 8.3 1.3 years). Visual motor control (VMC) and upper limb speed and dexterity (ULSD) items of the Bruininks-Oseretsky Test of Motor Proficiency were assessed, and logMAR visual acuity (VA) and Randot stereopsis were measured. Multiple regression models were used to identify the visual determinants of fine motor skills performance. RESULTS. Amblyopes performed significantly poorer than control subjects on 9 of 16 fine motor skills subitems and for the overall age-standardized scores for both VMC and ULSD items (P 0.05). The effects were most evident on timed tasks. The etiology of amblyopia and level of binocular function significantly affected fine motor skill performance on both items; however, when examined in a multiple regression model that took into account the intercorrelation between visual characteristics, poorer fine motor skills performance was associated with strabismus (F1,75 5.428; P 0.022), but not with the level of binocular function, refractive error, or visual acuity in either eye.--- CONCLUSIONS. Fine motor skills were reduced in children with amblyopia, particularly those with strabismus, compared with control subjects. The deficits in motor performance were greatest on manual dexterity tasks requiring speed and accuracy.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
