Description:
We have examined a pair of eyes 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 week. Even though a foveal depression existed, all cell layers were still present across it. Furthermore, the inner nuclear layer was divided into two separate layers. The receptor layer was reduced to one or two cells thick; receptors had both inner and outer segments, but they were very short and stumpy. The region of immaturity covered about 5 degrees of the retina. These findings suggest that the central region of a human infant's retina is probably not fully functional at birth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abramov, I -- Gordon, J -- Hendrickson, A -- Hainline, L -- Dobson, V -- LaBossiere, E -- EY01208/EY/NEI NIH HHS/ -- EY01523/EY/NEI NIH HHS/ -- EY01697/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Jul 16;217(4556):265-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178160" target="_blank"〉PubMed〈/a〉
