Intraocular pressure during 4-hydroxybutyrate narcosis.

Intraocular pressure during 4-hydroxybutyrate narcosis.

Intraocular pressure during phacoemulsification.

PURPOSE To assess changes in intraocular pressure (IOP) during standard coaxial or bimanual microincision phacoemulsification. SETTING Oregon Eye Center, Eugene, Oregon, USA. METHODS Bimanual microincision phacoemulsification (microphaco) was performed in 3 cadaver eyes, and standard coaxial phacoemulsification was performed in 1 cadaver eye. A pressure transducer placed in the vitreous cav...

Intraocular Pressure during Continuous Positive Airway Pressure

Intraocular pressure during cardiopulmonary bypass.

Intraocular pressure was measured in 24 patients undergoing elective cardiopulmonary bypass surgery. There was a rapid rise when the bypass circulation began, and this was maintained for about 30 minutes. A simultaneous drop in arterial perfusion pressure and packed cell volume occurred. We suggest that marked haemodilution is responsible for this effect, through increased ocular blood flow and...

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...
