The purpose of the study was to describe the influence of contralateral forced eyelid closure on intraocular pressure (IOP).
Twenty-one healthy volunteers with no ophthalmic history had their IOP measured in the supine position to simulate the intraoperative environment. Intraocular pressure was measured with a handheld tonometer over three scenarios: (1) both eyes in a relaxed state, (2) eyelid speculum in the right eye with both eyes open and relaxed, (3) eyelid speculum in the right eye with the fellow eye squeezing tightly.
Intraocular pressure significantly increased with forced contralateral eyelid squeezing compared with the relaxed state by a mean of 7.71±5.08 mm Hg (95% Confidence Interval of 5.40-7.37), P<0.001.
Contralateral eyelid squeezing can significantly increase intraoperative IOP measurements.
本研究旨在描述对侧强制闭眼对眼内压（IOP）的影响。
21 名无眼科病史的健康志愿者在仰卧位测量眼压，以模拟术中环境。使用手持式眼压计在三种情况下测量眼内压：（1）双眼放松状态，（2）右眼使用眼睑镜且双眼睁开放松，（3）右眼使用眼睑镜且对侧眼紧紧挤压。
与放松状态相比，强制对侧眼睑挤压时眼内压平均升高 7.71±5.08mmHg（95%置信区间为 5.40-7.37），P<0.001。
对侧眼睑挤压可显著增加术中 IOP 测量值。
