In general, if intraocular pressure rose over the bearable limits of optical inner structure that lead to damage of the optic nerve, visual field loss, and ultimately sight loss. Intraocular pressure is mainly determined by the coupling of the production of aqueous humor and the drainage of aqueous humor mainly through the trabecular meshwork located in the anterior chamber angle. Any abnormalities of structure leads to unbalanced process and blockage, the intraocular pressure increased. This study proposes a simulation mechanism of angle-closured glaucoma via elevating pressure applanated against vitreous body. To analyze the pressure of optical inner structure and design a model of complete eyeball including aqueous humor and vitreous body. This process is associated with increased intraocular pressure resulting from malfunction of aqueous drainage structures and malformation of vitreous body. Hence it damages the surrounding structures including optic nerves.
