title: A morphological study of the retinal ganglion cells of the Afghan pika (Ochotona rufescens).
abstract: The distribution and morphology of the retinal ganglion cells was studied in a relative of the rabbit, the Afghan pika. The total number of retinal ganglion cells was approximately 170,000. The total number of optic nerve fibers was between 160,000 and 190,000, corresponding to the total number of retinal ganglion cells. Retinal ganglion cells were found to have a horizontal region of high-density. The maximum density was 5250 cells/mm2. This region was located in the central retina below the optic disc. This area contained numerous closely packed small ganglion cells, while the peripheral retina (especially in the dorsal periphery) contained large ganglion cells more loosely dispersed. The retinal ganglion cells labeled by horseradish peroxidase (HRP) were morphologically classified into three types based on dendritic length and ramification pattern.
