There is increasing clinical evidence that the eye is not only affected by intraocular pressure (IOP), but also by intracranial pressure (ICP). Both pressures meet at the optic nerve head of the eye, specifically the lamina cribrosa (LC). The LC is a collagenous meshwork through which all retinal ganglion cell axons pass on their way to the brain. Distortion of the LC causes a biological cascad...

although measurement of intracranial pressure by noninvasive methods has been suggested, but mainly invasive methods are used for this purpose-increase in episcleral venous pressure can be expected to result in a linear increase in intraocular pressure. congested oculat veins with capillary leakage and hemorrhage are seen when the icp is increased, thus theoretically measurement of intraocular ...

Cerebral perfusion pressure (CPP) is the difference between mean arterial pressure (MAP) and intracranial pressure (ICP). Traditionally, management of traumatic brain injury (TBI) depended mainly on ICP control strategies. Based on the evidence that cerebral ischemia plays a major role in causing poor neurological outcome in traumatic brain injury (TBI) and cerebral blood flow autoregulation is...

Idiopathic intracranial hypertension (IIH), also known as primary pseudotumor cerebri syndrome (PTCS), is a condition of unknown etiology which affects primarily overweight, reproductive-aged women and causes increased intracranial pressure (ICP). This review discusses the recently revised diagnostic criteria for PTCS for adults and children. Additionally, the role of obesity in the epidemiolog...

The physiological effect of posture on intracranial pressure (ICP) is not well described. This study defined and evaluated three mathematical models describing the postural effects on ICP, designed to predict ICP at different head-up tilt angles from the supine ICP value. Model I was based on a hydrostatic indifference point for the cerebrospinal fluid (CSF) system, i.e., the existence of a poi...

Objective: Monitoring of intracranial pressure (ICP) is a routine procedure in the neurosurgery field. Although the routine practice of monitoring ICP has decreased in recent years, the practice patterns have not been studied in Colombia. This study was designed to evaluate the current practice forventriculostomy and ICP monitoring by neurosurgeons in Colombia. Methods...

This paper attempts to predict Intracranial Pressure (ICP) based on features extracted from non-invasively collected patient data. These features include midline shift measurement and textural features extracted from Computed axial Tomography (CT) images. A statistical analysis is performed to examine the relationship between ICP and midline shift. Machine learning is also applied to estimate I...

The understanding of raised intracranial pressure (ICP) is increasing with the directed use telemetric ICP monitors. This case uniquely observed changes by monitoring in a patient idiopathic hypertension (IIH), who developed rapid sight-threatening disease. A lumbar drain was inserted, as temporising measure, and clamped prior to surgery. resulted rise ICP, which normalised after insertion vent...

OBJECTIVE We evaluated the correlation between intracranial (ICP) and intraocular pressure (IOP). METHODS Of the 77 patients who underwent a lumbar puncture, 27 were excluded secondary to a history of glaucoma, using drugs effective on IOP, and abnormal funduscopic examination. ICP was measured by lumbar puncture. IOP was measured by two scales of Schiotz tonometer in both eyes, and the mean ...
