Ocular elongation and retraction in foveated reptiles

Abstract: Background: Pronounced asymmetric changes in ocular globe size during eye development have been observed in a number of species ranging from humans to lizards. In contrast, largely symmetric changes in globe size have been described for other species like rodents. We propose that asymmetric changes in the three-dimensional structure of the developing eye correlate with the types of retinal remodeling needed to produce areas of high photoreceptor density. To test this idea, we systematically examined three-dime… Show more

“…Eyes were processed using PBS, ethanol, and Xylene solutions along with paraffin waxes as previously reported (Rasys, Pau, Irwin, Luo, Kim, Wahle, Trainor, et al, 2021). Eyes were then serial sectioned in paraffin wax on the horizontal plane along the dorsal-ventral axis.…”

“…Outside of primates and birds, the only other foveated vertebrate to have the development of its eye studied is the brown anole lizard ( Anolis sagrei ) (Rasys, Pau, Irwin, Luo, Kim, Wahle, Trainor, et al, 2021; Rasys, Pau, Irwin, Luo, Kim, Wahle, Menke, et al, 2021; Rasys, Pau, Irwin, Luo, Menke, et al, 2021). This species relies on sight as its principal sense and requires a high degree of visual acuity for hunting its prey and communicating and socially interacting with others of its kind (Fleishman et al, 1995; Fleishman & Pallus, 2010).…”

“…The human eye contains a unique anatomical structure called the macula and its central portion, the fovea, rich in cone photoreceptors [ 72 , 73 ]. The morphogenetic processes underlying cone-dominant foveal development can be only partially inferred from other model organisms (e.g., 13-line ground squirrels, chameleons, and other reptiles) [ 74 , 75 , 76 ]. The human eye can accommodate lenses to both near-sight focus and over a distance of several hundreds of meters.…”
