Abstract

Differential stretch of a retinal surface with an initially uniform cell density has been repeatedly implicated as one of the developmental mechanisms that produces the topographic organization of cell density in the adult retina, notably the area centralis or visual streak versus peripheral regions. It is known that intraocular pressure is required to produce the normal conformation and thinning of the retina during development. We tested the possibility that the retina has elastic properties that might permit differential stretch in conjunction with intraocular pressure. The relative deformation of the retina containing the presumptive area centralis was compared to the deformation of peripheral retina at equivalent applied fluid displacements in 7–12-day-old cats. The peripheral retina deformed significantly more, consistent with the hypothesis that differences in the local elasticities of the developing neural retina contribute to its characteristic topographic changes. Thus, a biomechanical property of the growing eye may contribute to the mechanism by which the pattern of the visual array is sampled.
