Evaluation of the diurnal intraocular pressure fluctuations and blood pressure under dehydration due to fasting
Introduction: This study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. Methods: The intraocular pressures (IOP), body weights, as well as systolic and diastolic blood pressures (SBP, DBP) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...

متن کاملMechanical Effects of Radiation Pressure Quantum Fluctuations
As revealed by space-time probing, mechanics and field theory come out as complementary descriptions for motions in space-time. In particular, quantum fields exert a radiation pressure on scatterers which results in mechanical effects that persist in vacuum. They include mean forces due to quantum field fluctuations, like Casimir forces, but also fluctuations of these forces and additional forc...
متن کاملFluctuations in intraocular pressure increase the trabecular meshwork extracellular matrix.
BACKGROUND/AIMS The trabecular meshwork (TM) tissue is constantly exposed to dynamic stress caused by intraocular pressure (IOP). The effects of such biomechanical stress on the TM have not been analyzed. This study developed an animal model of fluctuating IOP and evaluated the effects of these fluctuations on TM tissue. METHODS To create fluctuation in the IOP, one eye of adult SD rats was e...
متن کاملTransient intraocular pressure elevation after trabeculotomy and its occurrence with phacoemulsification and intraocular lens implantation.
PURPOSE To elucidate the characterization of intraocular pressure (IOP) spike after trabeculotomy, and after the combined procedure of phacoemulsification and aspiration (PEA) and intraocular lens (IOL) implantation. METHODS Included in this study were 39 patients (53 eyes) with primary open-angle glaucoma with IOPs uncontrolled even with anti-glaucoma medication. We conducted a retrospective...
