Risk Factors for Intraocular Pressure Elevation in Steep Trendelenburg Position During Surgery.

Area of Science:

• Ophthalmology
• Anesthesiology
• Surgical Innovation

Background:

• Intraocular pressure (IOP) monitoring is crucial during surgical procedures.
• The steep Trendelenburg position (STP) is utilized in various surgeries, including total laparoscopic hysterectomy (TLH).
• Potential impacts of STP on IOP require thorough investigation.

Purpose of the Study:

• To assess the effect of STP on IOP during TLH.
• To explore correlations between IOP changes and patient factors (age, BMI, iridocorneal angle) and surgical duration.

Main Methods:

• Ophthalmologic evaluation and IOP measurements at multiple time points before, during, and after TLH.
• Handheld contact tonometer used for IOP assessment.
• Recording of surgery duration and patient demographics.

Main Results:

• IOP was significantly elevated at all measured time points compared to baseline.
• No significant correlation found between age or iridocorneal angle and IOP.
• A positive correlation between IOP and BMI, and a negative correlation between IOP and surgical duration were observed at the end of surgery.

Conclusions:

• STP significantly increases IOP during TLH.
• Higher BMI is associated with a more pronounced IOP elevation.
• Identifying high-risk patients can inform strategies to mitigate ocular complications.
