Quantitative Rise in Intraocular Pressure in Steep Trendelenburg Position

Quantitative Rise in Intraocular Pressure in Steep Trendelenburg Position

This study analyse the rise in Intraocular Pressure while patient is in surgery in head low position.

Patient undergoing robotic surgeries requires steep trendelenburg position (upto 60 degrees) along with pneumoperitoneum. These both can cause a significant rise in intraocular pressure. Significant rise of pressure for prolonged period can cause post operative visual disturbances, which can be of medicolegal importance. Thus studying the quantitative rise and thus trend of intraocular pressure is first step in managing ophthalmic changes during robotic surgeries.

Inclusion Criteria:

• American Society of Anaesthesiologists (ASA) status 1-3
• without any ophthalmic complains or interventions

Exclusion Criteria:

• lasix given during preoperative or intraoperative period
• cardiac patients who are on medications for stents or post Coronary Artery Bypass Graft (CABG)
• pre-existing glaucoma, eye surgeries, cataract or retinal vascular diseases, corneal diseases which may affect IOP measurement were excluded
