A Morphoelastic Shell Model of the Eye

The eye grows during childhood to position the retina at correct distance behind lens enable focused vision, a process called emmetropization. Animal studies have demonstrated that this growth is dependent upon visual stimuli, while genetic and environmental factors affect likelihood of developing myopia also been identified. coupling between growth, remodeling elastic response in particularly challenging understand. To analyse coupling, we develop simple model an growing under intraocular pressure stimuli. Distinct existing three-dimensional finite-element models eye, treat sclera as thin axisymmetric hyperelastic shell which undergoes local external stimulus. This simplified analytic provides tractable framework evaluate various emmetropization hypotheses understand different types feedback, exemplify by demonstrating laws are sufficient tune global size shape for vision across range parameter values.
