Investigation of the biomechanical environment within the optic nerve head by finite element modelling

摘要: Publisher Summary This chapter aims at evaluating the role of mechanical stresses in development glaucomatous optic neuropathy. It uses methods, such as a simplified “generic” model nerve head was created—consisting sclera, pre-laminar neural tissue, lamina cribrosa, and post-laminar tissue. The biomechanical environment is simulated using finite element method, results are compared with experimental measurements pressure-induced deformation tissues. result obtained from method that computed pattern anterior retinal surface similar to measured experimentally changes topography function pressure differences between parameterized normal eyes. qualitative correspondence model; topographic change, change consistent assumption stress related
