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.
采用动态视野计测量了77名足月儿的双眼视野范围，这些足月儿在新生儿期、4周龄或8周龄时接受了测试，测量方向为8个。该仪器由一个黑色的四臂弧形视野计、一个位于中央的6度固定白色球体以及一个作为周边目标的相同球体组成。与4周龄和8周龄的婴儿相比，新生儿的视野更大，这可能是由于较大婴儿对中央目标的注视更有力。所有年龄段的婴儿视野均显著小于成年人。然而，婴儿和成年人的视野形状相似。
