Zero retinal vein pulsation amplitude extrapolated model in non-invasive intracranial pressure estimation

Scientific Reports, 2022
Intracranial pressure (ICP) includes the brain, optic nerve, and spinal cord pressures; it influences blood flow to those structures. Pathological elevation in ICP results in structural damage through various mechanisms, which adversely affects outcomes ...

Ocular Rigidity, Ocular Pulse Amplitude, and Pulsatile Ocular Blood Flow: The Effect of Intraocular Pressure

Investigative Opthalmology & Visual Science, 2009
The purpose of this study was to characterize the pressure-volume relation in the living human eye, measure the ocular pulse amplitude (OPA), and calculate the corresponding pulsatile ocular blood flow (POBF) in a range of clinically relevant IOP levels.Fifty patients with cataract (50 eyes) were enrolled in the study. After cannulation of the anterior

Intraoperative Neurophysiological Monitoring for Endoscopic Endonasal Approaches to the Skull Base: A Technical Guide. [PDF]

, 2016
Intraoperative neurophysiological monitoring during endoscopic, endonasal approaches to the skull base is both feasible and safe. Numerous reports have recently emerged from the literature evaluating the efficacy of different neuromonitoring tests during

Ocular Rigidity, Ocular Pulse Amplitude, and Pulsatile Ocular Blood Flow: The Effect of Axial Length

Investigative Opthalmology & Visual Science, 2013
Previous studies have shown a negative correlation between axial length (AL) and pulsatile ocular blood flow (POBF). This relation has been questioned because of the possible confounding effect of ocular volume on ocular rigidity (OR). The purpose of this study was to investigate the relation between AL, as a surrogate parameter for ocular volume, and ...

Reduced ocular pulse amplitude in low tension glaucoma is independent of vasospasm [PDF]

Eye, 1997
A vascular basis for the pathogenesis of primary open angle glaucoma has been postulated for many years. Defects in the regulation of ocular blood flow may be the initiating factor in this group of multifactorial diseases. This study was designed to evaluate the effect of vasospasm on ocular pulse amplitude (OPA) in low tension glaucoma (LTG) patients ...
