The electroretinographic (ERG) response to patterns of constant mean luminance (sinusoidal gratings reversed in contrast at 12 rev/s) has been recorded in infants 7 weeks to 6 months old. At each age the amplitude of the ERG for relatively fine gratings decreases with increasing spatial frequency and vanishes for a spatial frequency that can be defined as ERG acuity. It has been found that ERG acuity increases progressively with age. The acuity evaluated from cortical evoked potentials (VEP) recorded simultaneously with the ERG increases with age in parallel with ERG acuity. These findings are in agreement with data reported in the literature for the cat, indicating a parallel postnatal development of acuity at a retinal and cortical level.
已记录了7周龄至6月龄婴儿对恒定平均亮度模式（以12转/秒反转对比度的正弦光栅）的视网膜电图（ERG）反应。在每个年龄段，相对精细光栅的ERG振幅随空间频率增加而降低，并在可定义为ERG视力的空间频率处消失。研究发现，ERG视力随年龄逐渐增加。与ERG同时记录的皮层诱发电位（VEP）评估的视力随年龄增长，与ERG视力平行。这些发现与文献中报道的猫的数据一致，表明视网膜和皮层水平的视力在出生后平行发展。
