Abstract The purpose of this project was to study the effect of intraocular pressure (IOP) stress on the cross section of the optic nerve. Specifications for the dimensional model based on a digital image of a person's eyes to the inner radius of the eye: 12 mm, sclera thickness mm 0.8 and cross section optic nerve: a circle of radius of 1.75 mm was done by the intraocular pressure to 15 mm Hg or 2 Kpa was considered.Using this model considers stress as a side effect placed on the optic nerve in an arbitrary and disparate examination. Within the two different kinds of models, both the sclera and the nerve are considered the properties of each from theanalysis softwareis incorporated. Utilizing software with element solid 95 for the analysis can create a whole model grid analysis, and the model is intended to be an isotropic model.The model results showed the effects of intraocular pressure and stress levels in the central area of the sclera. The surrounding area around the nerve is greater and the surrounding area of the nerve level is lower than the range. The damages created the eyes as a result of the upward pressure first started from the surrounding area of the eye and eventually, the function of the nerve is destroyed and because these areas are very sensitive, to have knowledge of the change in tension is very important for us. Even slight pressure can cause applied tension to the optic nerve, leading to nerve damage that becomes irreparable.
