Twenty infants and toddlers were determined to be visually impaired based on an ophthalmological examination and electrophysiological testing (Visual Evoked Response). To assess changes in visual-motor function with age, the 20 visually impaired infants and toddlers were followed, longitudinally, with the Bayley Mental Scale of Infant Development (BMSID). Based on the longitudinal BMSID data the study revealed the infants and toddlers obtained a range of scores. The results of the BMSID are discussed within the context of its role as a comprehensive assessment tool that charts changes in the visual-motor function of visually impaired children.
