The grating acuity of preterm infants was determined by measurements of the visual evoked potential (VEP) produced by phase alternation of sinusoidal luminance gratings. The development of visual acuity in healthy preterm infants appears to be accelerated when compared with full term infants of the same post-conceptual age. Cortical insults and the more advanced stages of retinopathy of prematurity may adversely affect acuity development as indexed by the VEP. Preterm twins also appear to have lower acuity than preterm monoparous infants.
通过测量由正弦亮度光栅的相位交替产生的视觉诱发电位（VEP）来确定早产儿的光栅视力。与相同孕龄的足月儿相比，健康早产儿的视力发育似乎更快。皮质损伤和早产儿视网膜病变的更晚期阶段可能会对以VEP为指标的视力发育产生不利影响。早产双胞胎的视力似乎也比早产单胎婴儿低。
