determination of central venous pressure from intraocular pressure

Determination of Central Venous Pressure from Intraocular Pressure

Background: In many clinical situations, knowledge of central venous pressure (CVP) is important.  Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  Those with carotid artery or jugular venous diseases as we...

Intraocular Pressure Reduction Is Associated with Reduced Venous Pulsation Pressure

PURPOSE To explore whether alterations in intraocular pressure (IOP) affect vein pulsation properties using ophthalmodynamometric measures of vein pulsation pressure. PATIENTS AND METHODS Glaucoma patients had two retinal vein pulsation pressure (VPP) measurements from upper and lower hemiveins performed by ophthalmodynamometry at least 3 months apart. All subjects had VPP and IOP recorded at...

peripheral venous pressure as a predictor of central venous pressure in continuous monitoring in children

Influence of tissue pressure on central venous pressure/peripheral venous pressure correlation: An experimental report.

BACKGROUND Peripheral venous pressure (PVP) has been shown to correlate with central venous pressure (CVP) in a number of reports. Few studies, however, have explored the relationship between tissue pressure (TP) and PVP/CVP correlation. METHODS PVP and CVP were simultaneously recorded in a bench-top model of the venous circulation of the upper limb and in a single human volunteer after under...

Continual monitoring of intraocular pressure: effect of central venous pressure, respiration, and eye movements on continual recordings of intraocular pressure in the rabbit, dog, and man.

A new method has been devised for continual monitoring of intraocular pressure by radiotelemetry. The use of this instrument for monitoring intraocular pressure by a variety of ophthalmic conditions is described.

Intraocular pressure and central corneal thickness.

From the results of the Ocular Hypertension Treatment Study emerged the conclusion that ocular hypertensive subjects with thinner central corneal thickness (CCT) are at increased risk of developing glaucoma. Although possible underlying biases that could have led to this conclusion are still under investigation, there is an increasing interest in the scientific community to understand the poten...
