To assess the impact of various body and head positions on intraocular pressure (IOP) in cataract patients aged over 40 years with limited mobility. This cross-sectional study was conducted between August and December 2023 at Aier Eye Hospital of Wuhan University. The IOP was measured using a handheld tonometer (iCare IC200 rebound tonometer) in various head positions (forward, tilted left, and tilted right) and body positions: supine, semirecumbent, sitting, and prone. In the supine position, the IOP measurements for the head positioned forward, right, and left were (13.80 ± 3.62) mmHg, (14.25 ± 3.66) mmHg, and (13.78 ± 3.40) mmHg, respectively. In the semirecumbent position, the corresponding IOPs were (12.08 ± 3.34) mmHg, (12.12 ± 3.22) mmHg, and (12.04 ± 3.38) mmHg. In the sitting position, the IOPs were recorded as (11.73 ± 3.29) mmHg, (11.73 ± 3.22) mmHg, and (11.59 ± 3.17) mmHg. Lastly, in the prone position, the IOPs were (14.19 ± 3.73) mmHg, (14.42 ± 3.93) mmHg, and (14.74 ± 3.81) mmHg, respectively. In each position group, there was no statistically significant difference in IOP among the three head positions. Regardless of the head position, the IOP is lowest in the sitting position, followed by semirecumbent and supine positions, with the prone position having the highest IOP. The analyses revealed that central corneal thickness (CCT) was correlated with an IOP value ( < 0.05) when patients were in different positions. IOP is influenced by body position. As the body transitions from upright to horizontal, IOP tends to increase. The position of the head, however, has no effect on IOP.
评估不同身体和头部姿势对行动不便的40岁以上白内障患者眼压（IOP）的影响。这项横断面研究于2023年8月至12月在武汉大学爱尔眼科医院进行。使用手持眼压计（iCare IC200回弹眼压计）在不同头部姿势（向前、向左倾斜和向右倾斜）和身体姿势（仰卧、半卧位、坐姿和俯卧位）下测量眼压。在仰卧位时，头部向前、向右和向左时的眼压测量值分别为（13.80±3.62）mmHg、（14.25±3.66）mmHg和（13.78±3.40）mmHg。在半卧位时，相应的眼压分别为（12.08±3.34）mmHg、（12.12±3.22）mmHg和（12.04±3.38）mmHg。在坐姿时，眼压记录为（11.73±3.29）mmHg、（11.73±3.22）mmHg和（11.59±3.17）mmHg。最后，在俯卧位时，眼压分别为（14.19±3.73）mmHg、（14.42±3.93）mmHg和（14.74±3.81）mmHg。在每个姿势组中，三种头部姿势下的眼压无统计学显著差异。无论头部姿势如何，坐姿时眼压最低，其次是半卧位和仰卧位，俯卧位时眼压最高。分析显示，当患者处于不同姿势时，中央角膜厚度（CCT）与眼压值相关（<0.05）。眼压受身体姿势影响。随着身体从直立状态转变为水平状态，眼压往往会升高。然而，头部位置对眼压没有影响。
