Scleral biomechanics and glaucoma--a connection?
I ntraocular pressure (IOP) is well known to play an important role in the pathogenesis of some forms of glaucoma. Furthermore, significant, sustained pressure reduction is known to be beneficial in the clinical management of glaucoma patients. 1 Less well understood is the mechanism by which elevated IOP leads to the loss of retinal ganglion cells that is the hallmark of glaucomatous optic neu...
متن کاملScleral biomechanics in the aging monkey eye.
PURPOSE To investigate the age-related differences in the inhomogeneous, anisotropic, nonlinear biomechanical properties of posterior sclera from old (22.9 +/- 5.3 years) and young (1.5 +/- 0.7 years) rhesus monkeys. METHODS The posterior scleral shell of each eye was mounted on a custom-built pressurization apparatus, then intraocular pressure (IOP) was elevated from 5 to 45 mm Hg while the ...
متن کاملThe scleral spur and scleral roll.
The scleral spur and scleral roll together form a fibrous hoop which may be detached from adjacent structures as a unit. Tensile tests of the spur-roll resemble reported data on sclera. It is proposed that the circular structure of the spur-roll prevents action of the meridional portion of the ciliary muscle on the trabecular meshwork from collapsing the canal of Schlemm.
متن کاملFluid-structure interaction with applications in biomechanics
In bioengineering applications problems of flow interacting with elastic solid are very common. We formulate the problem of interaction for an incompressible fluid and an incompressible elastic material in a fully coupled arbitrary Lagrangian-Eulerian formulation. The mathematical description and the numerical schemes are designed in such a way that more complicated constitutive relations (and ...
متن کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
