Hamster retinas were examined by light and electron microscopy during the first 15 postnatal days and at the adult stage. At birth, these retinas were more primitive than those of other rodents, but eventually they became very similar. Initial postnatal growth and development were more rapid than in other rodents of comparable ages. Mitotic figures were present throughout the first 9 days. The primitive inner plexiform layer formed during days 2 to 4; on day 7, several developmental changes became apparent: outer segment disks of the photoreceptor cells formed from flattened, smooth vesicles, horizontal cells became readily identifiable, the outer plexiform layer appeared, and ribbon synapses formed in the receptor cell axon terminals. By day 11, there were numerous conventional synapses in the inner plexiform layer, and ribbon synapses were beginning to appear in the terminal portions of the bipolar axons. The retinal tissue was progressively invaded by developing vasculature. The first photoreceptor outer segment disks formed from smooth membranous vesicles flattening radially around the ends of the connecting cilium. After the outer segment assumed a more mature appearance, with a stacked disk arrangement, further disk formation occurred by plasma membrane infoldings at the outer segment base. The adult hamster retinas were similar to those of other rodents.
在出生后的前15天以及成年阶段，对仓鼠视网膜进行了光镜和电镜检查。出生时，这些视网膜比其他啮齿动物的视网膜更原始，但最终它们变得非常相似。出生后的最初生长和发育比同龄的其他啮齿动物更快。在最初的9天内都存在有丝分裂图像。原始的内网状层在第2至4天形成；在第7天，几个发育变化变得明显：光感受器细胞的外节盘由扁平、光滑的囊泡形成，水平细胞变得易于识别，外网状层出现，并且在受体细胞轴突终末形成了带状突触。到第11天，在内网状层中有许多传统突触，并且带状突触开始出现在双极轴突的终末部分。视网膜组织逐渐被发育中的血管系统侵入。第一个光感受器外节盘由围绕连接纤毛末端径向扁平的光滑膜性囊泡形成。在外节呈现出更成熟的外观，具有堆叠的盘状排列后，通过外节基部的质膜内陷发生进一步的盘形成。成年仓鼠视网膜与其他啮齿动物的视网膜相似。
