Visual acuity was measured in both preterm and full-term infants by means of forced-choice preferential looking. The ages of infants tested ranged from one month to 12 months. The results of both groups were considered and compared in terms of natal and conceptional age. The data suggested that preterm infants show visual responses equivalent to their full-term counterparts by nine months of age. Trends indicate that visual acuity development in healthy preterm infants appears to be accelerated when compared with full-term infants of the same post-conceptional age.
通过强迫选择优先注视法测量了早产儿和足月儿的视力。接受测试的婴儿年龄从1个月到12个月不等。根据出生年龄和孕龄对两组结果进行了考量和比较。数据表明，早产儿在9个月大时视觉反应与足月儿相当。趋势表明，与相同孕龄的足月儿相比，健康早产儿的视力发育似乎加快了。
