    Abstract: 本研究以建立數值模型對隅角閉鎖型青光眼的生成與發病機制進行模擬與分析,設計出包含眼球前後房、水晶體、玻璃體、視神經盤、鞏膜、篩版的完整眼球模型,模擬從後房房水生成到受阻,以致於眼壓升高對於水晶體、玻璃體產生壓迫的狀況,做出一套完整的模擬,探討視神經盤受到壓力產生的影響。

    In this study, to establish numerical model for angle-closure glaucoma pathogenesis generation and simulation and analysis, design includes eye with anterior chamber, posterior chamber, lens, vitreous, optic nerve head, Sclera, lamina, the full eye model, simulation from Posterior chamber aqueous humor formation to blocked, So that intraocular pressure increased caused lens, vitreous oppressive situation, make a complete set of simulations, exploration of optic nerve head under pressure impacts.

    According to the study results of the two models to simulate, found that in angle closure glaucoma intraocular pressure generated with the transfer situations and affect the optic nerve behind the eye, leading to optic nerve head compression and caused vision defects, and we can see part in the eye with anterior chamber, posterior chamber, simulated pressures are in compliance with angle closure glaucoma clinical pressure range, part in the optic nerve head, two models stress figure and strain figure to the trend is compared did not differ much, trends consistent with the literature results. And get transmitted to lens, vitreous, optic nerve head, sclera, lamina, overall pressure distribution situation. This part of the clinically pressure are can''t be measured. This study established that a complete eye model, can be used as future analysis of angle-closure glaucoma one basis. For future related research, provides a valuable reference for numerical simulation analysis.
