[Role of ocular pulse amplitude in glaucoma].

Klinische Monatsblatter fur Augenheilkunde, 2015
The ocular pulse amplitude is defined as the difference between diastolic and systolic intraocular pressure. The ocular pulse is generated by the pulsatile ocular blood flow in the choroid. It is dependent on the dynamics of the cardiovascular system, the rigidity of the ocular vessels on one side and the biomechanical properties of the eye on the ...

Acetazolamide Influences Ocular Pulse Amplitude

Journal of Ocular Pharmacology and Therapeutics, 2009
To investigate the effect of systemic acetazolamide on ocular pulse amplitude (OPA) and on intraocular pressure (IOP).We determined OPA, IOP, mean arterial blood pressure and heart rate (HR) in 17 patients suffering from hypertensive primary open-angle glaucoma (htPOAG) and 22 healthy controls.

Ocular Pulse Amplitude in Myopia

Journal of Ocular Pharmacology and Therapeutics, 1991
We studied the ocular pulse amplitude of myopic patients by using Alcon Pneumotonography. One hundred and eighty-eight cases (376 eyes) were enrolled in this study. The results revealed that the higher the myopia the lower the ocular pulse amplitude. The pulse amplitude has high correlation with refractive error and axial length, but poor correlation ...

Amplitude-modulated composite pulses

Journal of Magnetic Resonance (1969), 1988
One of the most important developments in the field of magnetic resonance in the past decade has been the introduction of composite pulse sequences (I). These may be either several pulses of specified length and phase applied sequentially or a single complex pulse of continuously varying phase and/or amplitude which compensate for the imperfections ...

An Internal Heating Strategy for Lithium-Ion Batteries Without Lithium Plating Based on Self-Adaptive Alternating Current Pulse

IEEE Transactions on Vehicular Technology, 2023
AC pulse heating is a promising preheating method for lithium-ion batteries due to its low energy cost and high efficiency. To avoid the lithium plating in the AC heating, upper bound of heating current (UBHC) should be obtained.
