Our aim was to investigate the distribution of retinal ganglion cells and visual acuity in hedgehogs, nocturnal insectivores with reputedly poor vision. Adult Erinaceus europaeus and E. roumanicus, two hedgehog species found in Austria, were studied. The eyes were enucleated, fixed, and ocular anatomical parameters were measured. To identify retinal ganglion cells (RGCs), Brn3a, which is expressed by vision-forming RGCs, and RBPMS, which is expressed by vision- and non-vision-forming RGCs, were visualized by fluorescence immunolabeling of retinal frozen sections and wholemounts.
