* 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.
