          Abstract

          Kinetic perimetry was used to measure the extent of the binocular visual field in 8 directions in 77 full-term infants tested as neonates, 4-week-olds, or 8-week-olds. The apparatus consisted of a black, 4-arm arc perimeter, a centrally-located 6-deg stationary white sphere, and an identical sphere that served as the peripheral target. Neonates showed larger visual fields than did 4- and 8-week-olds, perhaps due to the strength of the older infants' fixation of the central target. Infants at all ages showed significantly smaller fields than did adults. However, visual field shape was similar in infants and adults.
