CALDERIN PEREZ, Bernardo; GONZALEZ CARBONELL, Raide Alfonso; LANDIN SORI, Matilde  and  NAPOLES PADRON, Elsa. Applicability of computational simulation in the biomechanics of the optic disc. AMC [online]. 2015, vol.19, n.1, pp.73-82. ISSN 1025-0255.

Background: intraocular pressure causes tension and deformities in the tissues of the optical disc that can entail glaucomatous damage. Objective: to simulate the biomechanical behaviour of the optical disc and describe its applicability in the prediction of glaucomatous damage. Method: Finite Element Method was the computational simulation tool used. An intraocular pressure of 15 mm Hg was used, as well as the mechanical properties and geometry of tissues of the optic papilla reported in the literature. Development: most of the concentrations of tension appear at the level of the peripapillary sclera and were consistent with the estimations reported in the literature. Scleral stiffness had an influence on the tension transmitted to the lamina cribosa sclerae. This tissue was the most susceptible to glaucomatous damage in the optical papilla. Conclusions: the preliminary obtained analysis is a starting point for the study of the optic nerve by means of the computational simulation. It was proved that intraocular pressure, the complexity of the geometry and the mechanical characteristics of the tissues of the head of the optic nerve are determining factors of the glaucomatous damage.
