摘要	Vision plays an important role in the living habits of animals, especially in feeding. We investigated the postnatal development of retina in root vole Microtus oeconornus. The result shows that the retina of the M. oeconornus is very primitive before postnatal day （PD） 3. The neuroblastic layer does not differentiate and makes up more than half of the retina layer. The outer plexiform layer （OPL） first comes into existence at PDS. At PD6, as the presence of the OPL becomes obvious, the outer nuclear layer （ONL） and inner nuclear layer （INL） are much clearer. At PD18, the retina is similar to an adult retina and each layer becomes distinct. The thickness and cell density of the ganglion cell layer （GCL） and ONL during different postnatal days were also examined. These results show that the thickness and density of ONL increase during ontogeny, while the thickness and density of GCL decrease. Compared with Rattus norvegicus, Apodemus agrarius , Cricetulus triton, Microtus mandarinus , Myospalax cansus , Spermophilus dauricus and Sciurotamias davidianus, the histological structure of the retina of M. oeconornus is between that of nocturnal and diurnal rodents.; Vision plays an important role in the living habits of animals, especially in feeding.
