Unilateral anophthalmia in a Holstein calf was examined morphologically. On the left side, a small cystic remnant of the eye ball (CRE) was present in the orbit. The CRE was adhered to the dura mater through an abnormal foramen formed in the orbital region of the cranial base. At this region of the left cerebral hemisphere, a porencephalic change was detected. Histologically, the pigment epithelium was continued from the lining of the inner surface of CRE to the residual cerebrocortical tissue attached to the dura mater. These characteristic changes seem to suggest the partial fusion of the outer layer of the optic cup to the telencephalon during optic organogenesis.
对一头荷斯坦犊牛的单侧无眼球症进行了形态学检查。在左侧眼眶内存在一个眼球的小囊性残余物（CRE）。CRE通过颅底眶区形成的异常孔与硬脑膜相连。在左脑半球的该区域检测到脑穿通性改变。组织学上，色素上皮从CRE内表面的衬里延续至附着于硬脑膜的残余大脑皮质组织。这些特征性改变似乎提示在视器官发生过程中视杯外层与端脑的部分融合。
