Evaluation of the diurnal intraocular pressure fluctuations and blood pressure under dehydration due to fasting
Introduction: This study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. Methods: The intraocular pressures (IOP), body weights, as well as systolic and diastolic blood pressures (SBP, DBP) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...
متن کاملDetermination 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...
متن کاملDoes the Renin-Angiotensin System (RAS) Regulate also Intraocular Pressure (IOP)?
The central role of Renin-Angiotensin System (RAS) in the regulation of blood pressure is widely accepted, and drugs which inhibit the formation of the potent vasoconstrictor angiotensin II (AngII) i.e. ACE inhibitors or drugs which block the Ang receptors of type 1 (AT1R) form the cornerstone in the treatment of hypertension. However, from AngI and AngII also vasodilating and blood pressure lo...
متن کاملReliable intraocular pressure measurement using automated radio-wave telemetry
PURPOSE To present an autonomous intraocular pressure (IOP) measurement technique using a wireless implantable transducer (WIT) and a motion sensor. METHODS The WIT optical aid was implanted within the ciliary sulcus of a normotensive rabbit eye after extracapsular clear lens extraction. An autonomous wireless data system (AWDS) comprising of a WIT and an external antenna aided by a motion se...
متن کاملIntraocular pressure reduction and regulation system.
The IOP reduction and regulation system performs certain specific functions: it can be used to lower (or raise) IOP in a controlled way; it responds rapidly to maintain a selectable, set, minimum IOP under variable flow demands; and it reduces the rapid dynamic increases in IOP resulting from loads applied to the eye. The system has been tested and evaluated in the laboratory with a small test ...
