用碳菁染料（DiI）逆行标记和荧光黄细胞内填充的方法，研究了鸡视网膜中央神经节细胞（RGCs）的分类。根据胞体面积、树突野的大小和树突的分枝方式，将神经节细胞分为Ic/Is组、IIc/IIs组、IIIs组和IVc组。Ⅰ组细胞胞体面积小，树突野小。根据树突状分支的复杂性（Ic亚组）和简单性（Is亚组）将它们进一步分为2个亚组。Ⅱ组细胞有中等大小的索马和树突状野。根据与Ic和Is亚组相同的定义，将其分为IIc和IIs亚组。III组为中等大小的索马，大而简单的树突状分支。Ⅳ c组细胞索马较大，树突状结构复杂。各组的细胞群分别为51.8%（亚组Ic）、21.1%（亚组Is）、6.2%（亚组IIc）、14.6%（亚组IIs）、4.2%（亚组IIs）和2.1%（亚组IVc）。亚组Ic细胞，这是非常相似的β-细胞在哺乳动物的中央区域，代表了约一半的神经节细胞的人口。在哺乳动物视网膜中未见报道的Ⅰ s和Ⅱ s亚群细胞，在鸡视网膜中央部有较高的数量（35.7%）。鸡视网膜中央节细胞的形态特征被认为是与其他脊椎动物的比较。
Classification of retinal ganglion cells (RGCs) in the chick central retina was studied by retrograde labeling of carbocyanine dye (DiI) and intracellular filling with Lucifer Yellow. Ganglion cells were divided into 4 groups, Group Ic/Is, Group IIc/IIs, Group IIIs, Group IVc, according to sizes of somal area and dendritic field and dendritic branching pattern. Group I cells had small somal area and small dendritic field. They were further divided into 2 subgroups by complexity (subgroup Ic) and simplicity (subgroup Is) of the dendritic arborization. Group II cells had medium-sized soma and dendritic field. They were also divided into subgroup IIc and IIs by the same definitions as those of subgroup Ic and Is. Group IIIs had medium-sized soma, large and simple dendritic arborization. Group IVc in which all cells had large soma, showed large and complex dendritic arborization. Cell populations of each group were 51.8% (subgroup Ic), 21.1% (subgroup Is), 6.2% (subgroup IIc), 14.6% (subgroup IIs), 4.2% (Group IIIs), and 2.1% (Group IVc). Subgroup Ic cells, which were very similar to beta-cells in the mammalian central area, represented about a half of the ganglion cell population. Cells in subgroup Is and IIs, which were not reported in the mammalian retina, were found in the chick central retina in relatively high population (35.7%). Morphological features of chick RGCs in the central retina were considered in comparison with those of other vertebrates.
