    Abstract: 青光眼為一種會造成視神經損害的疾病,當青光眼嚴重時甚至會導致患者永久性的失明,隅角開放型青光眼是目前國人最常見的一種青光眼,其因小樑網的異常導致房水排出不易,進而導致眼球後房的壓力堆積,並且對於視神經盤造成壓迫,最終導致視神經受損。
    Glaucoma is a kind of disease which will cause optic nerve damage. When the situation worsens, it may cause blindness. Open angle glaucoma is the most common form of glaucoma. Because of the anomalous state of the trabecular meshwork which will cause aqueous humor hard to be drained. Thus, pressure accumulates in the posterior chamber and causes extra force on the optic nerve in the back of the eye, in results doing damage to the nerve fibers.
    For better understanding of the pressure distribution on the optic disc which is transferred by the eyeball, we used finite element analysis software ANSYS in this study to simulate conditions of the aqueous humor in the anterior chamber for open angle glaucoma.
    All the analysis were divided into four parts, First of all, analysis of pressure in the eye for anterior chamber and posterior chamber. Secondly, analysis of pressure in the eyeball for vitreous body and optic disc. Thirdly, influence on the optic disc due to age and stress. Finally, influence of the Intraocular Pressure of the stress in the optic disc. Each part of these analysis were carefully examined. According to the results, when the pressure accumulate in posterior chamber, the pressure will be transferred by the way which passes by the lens to the optic disc and cause the oppression of the optic disc. In the end, it will cause optic nerve tissue necrosis.
