* Myopia results in changes to the eye’s biomechanical properties, particularly within the posterior pole, where the ocular tunics are thought to become thinner and may be more easily deformed by normal ocular forces such and intraocular pressure (IOP).udud* Acute elevations in IOP have been shown to increase axial length and optic cup dimensions, and decrease choroidal thickness; structural changes which are also associated with myopia.udud* High resolution optical coherence tomography (OCT) has allowed for investigation of biomechanical changes in the optic nerve and peripapillary choroid in vivo in response to IOP elevation in older glaucomatous eyes, but the effects in younger myopes have not been assessed.udud* This research examines the invluence of brief IOP elevation on peripapillary choroidal thickness (PPChT) in young adult myopes and emmetropes using Spectralis enhanced depth imaging OCT.

机译:*近视会导致眼睛的生物力学特性发生变化,尤其是在后极内,眼后束被认为变薄,并且在正常的眼力和眼内压(IOP)的作用下可能更容易变形。眼压升高显示增加轴向长度和视杯尺寸,并降低脉络膜厚度。结构变化也与近视有关。 ud ud *高分辨率光学相干断层扫描(OCT)可以研究体内视神经和老眼青光眼眼中IOP升高对视神经和乳头周围脉络膜的生物力学变化,但是尚未评估年轻近视眼的效果。 ud ud *本研究使用Spectralis增强深度成像OCT研究了短暂的IOP升高对年轻成人近视眼和正视眼的乳头周围脉络膜厚度(PPChT)的影响。
