Purpose: The Bayley Scales of Infant and Toddler DevelopmentIII (Bayley III) is a tool to measure the developmental status of young children in the first three years of life including cognitive and motor functioning. The purpose of this study was to evaluate the correlation between grating visual acuity and visual functionality through the Bayley III in healthy children. Methods: Binocular grating acuity (BGA) was measured by Teller acuity cards (TAC) followed by The Bayley Scales of Infant and Toddler DevelopmentIII (Bayley III) in healthy participants with term birth aging from 142 months. The inclusion criteria were: normal visual behavior observed by parents, aligned eyes, normal pediatric development and absence of neurological condition. The BayleyIII contains cognitive (91 items), language (97 items), motor (138 items), socialemotional (35 items), and adaptive behavior scales (241 items). Only cognitive and motor domain were included for analysis in the present study because of their direct repercussion on vision status. Scores from BGA (logMAR) and Bayley III scores for both cognitive and motor (gross and fine) skills were compared. The associations among the tests were evaluated through Stata Data Analysis and Statistical Software version 12. This protocol was approved by the Committee on Ethics in Research of UNIFESP and informed consent was provided from parents/guardians. Results: A group of 40 children (20 females; 50 %) with ages ranging from 1.2 to 42.1 months (mean=16.87 ± 10.34 months, median=14.5 months) was tested. BGA ranged from 0.01 to 1.06 logMAR (mean=0.39±0.27 logMAR; median=0.36 logMAR) and was within normal age limits for all participants. There was a strong and significant negative correlation between BGA and age (Pearson; r=0.82, P≤0.001). Cognitive raw data score ranged from 11 to 90 (mean=49.92±18.93 points; median=51.50 points), with a strong and significant positive correlation between cognitive score and age (Pearson; r=0.81, P≤0.001). Gross motor score ranged from 12 to 72 (mean=41.72 ± 16.23 points; median=40.00 points), with a strong and significant positive correlation between gross motor score and age (Pearson; r=0.75, P≤0.001). And fine motor score ranged from 4 to 60 (mean=39.75±14.63 points; median=41.50 points), with a strong and significant positive correlation between fine motor score and age (Pearson; r=0.77; P≤0.001). There was a significant correlation between BGA scores and cognitive, gross and fine motor scores respectively (r=0.73, p≤0.16; r=0.64 p≤0.05; r=0.69, p≤0.02). Conclusions: A high correlation was found in this study of healthy children between grating acuity threshold measured by TAC and cognitive and motor scores measured by Bayley III. These results showed that Bayley III might be a useful tool to assess the repercussion of visual impairment in the cognitive and motor development of young children in future studies.
