Visual Development of Healthy Full-Term Infants under 24 Months of Age Using the Preverbal Visual Assessment Questionnaire

As visual perception development proceeds rapidly after birth, early detection of developmental maturity is required. Healthy infants do not have many opportunities for visual perception evaluation, so a reliable evaluation method is necessary. This retrospective study included 276 healthy full-term infants p < 0.05). In those 12 month and above, no clinical factors were significantly associated with the PreViAs scores in all domains. The PreViAs questionnaire is a useful tool for visual assessment of healthy full-term infants under 24 months of age, suggesting reference values and cutoff scores according to age, and estimating the maturation age for visual perception development of each domain.
