| Summary: | 碩士 === 淡江大學 === 機械與機電工程學系碩士班 === 96 === Glaucoma, second only to cataract, is the major cause of losing eyesight in the world. Intraocular pressure is determined by the formation rate and shedding rate of aqueous humor. Intraocular pressure is raised through increased production or decreased outflow of aqueous humor.
As the angle gets blocked by part of the iris, the fluid at the front of the eye cannot reach the angle and leave the eye. Therefore, the intraocular pressure increases gradually. It is generally acknowledged that excessive intraocular pressure, beyond the upper limit of optic nerve able to bear, makes the neural vision to be damaged, the visual field to be shrunk, flawed and damaged.
The research in this thesis is conducted to study the pressure distributions in the posterior chamber of an eye for Angle-closure glaucoma. The numerical simulations are designed to find the pressure distribution in posterior chamber when the stress is transmitted from anterior chamber. The effects on optic nerve and cell around can be observed as the pressure distribution in posterior chamber changes.
