一对眼睛检查从正常，足月婴儿谁死于8天意外伤害的结果。死后立即取眼，固定，切片进行光学显微镜观察。两只眼睛的结果基本相同。黄斑区域在1周时仍明显不成熟。即使中央凹存在，所有的细胞层仍然存在。内核层被分成两层。受体层减少至1 ~ 2个细胞厚；受体有内外节，但非常短且粗壮。未成熟区约5度。视网膜的。显然，人类婴儿视网膜的中心区域在出生时可能没有完全发挥功能。
A pair of eyes was examined from a normal, full-term infant who died at 8 days as a result of accidental injury. Eyes were obtained immediately after death, fixed, and sectioned for light microscopy. Results from both eyes were substantially the same. The macular region was still drastically immature at 1 wk. Even though a foveal depression existed, all cell layers were still present across it. The inner nuclear layer was divided into 2 separate layers. The receptor layer was reducred to 1 or 2 cells thick; receptors had both inner and outer segments, but they were very short and stumpy. The region of immaturity covered about 5.degree. of the retina. Apparently, the central region of a human infant''s retina is probably not fully functional at birth.
