PURPOSE To study blood pressure (BP), intraocular pressure (IOP), and mean ocular perfusion pressure (MOPP) in patients with untreated normal tension glaucoma (NTG), and to investigate the relationship between circadian MOPP fluctuation and visual field status at initial presentation. METHODS IOP and BP were evaluated in hospital over 24 hours in 132 patients with NTG, with measurements taken...

PURPOSE To investigate systemic and ocular hemodynamic risk factors for glaucomatous damage in eyes with normal tension glaucoma (NTG). METHODS Each patient with diagnosed NTG underwent 24-hour monitoring of intraocular pressure (IOP) and blood pressure (BP), scanning laser polarimetry (GDx-VCC), and a Humphrey visual field (HVF) examination. Multivariate regression models were used to evalua...

OBJECTIVE To investigate the correlation between central corneal thickness and outflow facility assessed by intraocular pressure peak and fluctuation during the water drinking test. METHODS Fifty-five newly diagnosed primary open-angle glaucoma patients submitted to central corneal thickness measurements and water drinking test were enrolled in this retrospective study.;. Patients were divide...

This paper investigates the characteristics of wall pressure fluctuations in naturally developing boundary layer flows on axisymmetric bodies experimentally. The axisymmetric body has a modified ellipsoidal blunt nose. Flush-mounted microphones are used to measure the wall pressure fluctuations in the boundary layer flow over the body. The measurements are performed in a low noise wind tunnel. ...

Based on the actual experiment signals of draft tube, the correlation dimension analysis has been carried on using the time domain signals. Through correlation dimension analysis of pressure fluctuating under different load, the results indicate that the pressure fluctuation conditions in draft tube are not same under different load, the corresponding fractal correlation dimensions are also dif...

The fluctuation pressure of a lipid-bilayer membrane is important for the stability of lamellar phases and the adhesion of membranes to surfaces. In contrast to many theoretical studies, which predict a decrease of the pressure with the cubed inverse distance between the membranes, Freund suggested very recently a linear inverse distance dependence [Proc. Natl. Acad. Sci. USA 110, 2047 (2013)]....
