A radiate specialization, the aster, has been found in whole-mount retinas of birds and is associated to each one of the temporal and nasal fovea, with the one related to the convexiclivate nasal fovea more evident. This radial arrangement extends uniformly in all directions from the foveal pit. Transverse sections of the retina show that this structure is formed by bands of cells and bundles of fibers from the inner nuclear layer.
一种呈放射状特化的结构，即星芒状结构，已在鸟类的视网膜整装标本中被发现，并且与颞侧和鼻侧中央凹中的每一个都相关联，其中与凸面鼻侧中央凹相关的那个更为明显。这种放射状排列从中央凹坑向各个方向均匀延伸。视网膜的横切面显示，这种结构是由内核层的细胞带和纤维束形成的。
