GARZON-ALVARADO, Diego Alexander; ROA, Máximo Alejandro  y  RAMIREZ, Angélica María. Computational modeling of the ocular globe before intraocular pressure loads. Rev Cubana Invest Bioméd [online]. 2008, vol.27, n.3-4, pp. 0-0. ISSN 1561-3011.

A research that intends to establish a model of the mechanical behavior of the eye was developed for studying some eye diseases (myopia associated with an axial growth). A study of the scleral material was conducted to determine its behavior and with these data the model of the ocular globe was created by using finite elements to obtain the state of strain and deformation present in it when it is subjected to an increase of the intraocular pressure. To this end, the eye was analyzed using the Mooney Rivlin model for five constants presented by the so-called ANSYS. The results showed how the mechanical restrictions and the high intraocular pressure may generate outpouchings closed to the muscular insertion denominated staphylomas, which agreed with what was clinically observed
