Summary

Intra ocular pressure (IOP) may theoretically increase due to steep Trendelenberg position and studies showed that IOP reaches peak levels after steep Trendelenberg position on an average of 13 mmHg higher than preanesthesia induction values. Major determinants of IOP are aqueous humor flow, choroidal blood volume, central venous pressure and extra ocular muscle tone.

Hassen GW et al measured anterior chamber depth in 2 patients with glaucoma and compared the anterior chamber depth (ACD) with the intraocular pressure measured by tonometer. They concluded that bedside ultrasound could be useful in evaluating patient with suspected increased IOP, who are unable to open their eyes.

Conditions

Interventions

DEVICE

IOP by tonometer

Electronic tonometer will be used as gold standard for intraocular pressure measurement in supine position after induction of anaesthesia and every 2 hours intraoperatively and at end of surgery.

DEVICE

Anterior chamber depth measurement by ultrasound

Anterior chamber depth will be measured by ultrasound in supine position after induction of anaesthesia and every 2 hours intraoperatively and at end of surgery.
