摘要
目的:探讨体位对眼压测量的影响。方法前瞻性研究。选择POAG患者32例( POAG组)与健康人28名(健康人组),使用Perkins压平眼压计分别测量坐位、平卧位、右侧卧位及左侧卧位下的眼压,然后让患者坐起分别测量重新坐起后1、5、10 min的眼压。采用方差分析比较POAG患者与健康人在不同睡眠姿势下眼压的差别、POAG患者与健康人相比眼压升高幅度的差别以及重新坐起后不同时间点与坐位眼压的差别。结果在健康人组,右眼在坐位、平卧位、右侧卧位、左侧卧位下的眼压分别为(17.5±3.8),(19.3±3.1),(21.7±3.7)及(21.5±3.7) mmHg(1 mmHg=0.133 kPa);左眼在上述体位下的眼压分别为(18.4±3.0)、(19.3±3.1)、(20.7±2.9)及(22.8±4.0)mmHg。在POAG组,右眼在坐位、平卧位、右侧卧位、左侧卧位下的眼压分别为(17.9±3.7)、(20.6±4.6)、(26.1±7.1)及(26.3±5.9) mmHg;左眼在上述体位下的眼压分别为(18.2±3.6)、(20.0±4.1)、(25.6±6.1)及(25.7±6.0) mmHg。开角型青光眼患者在右侧卧位下(右眼 F =11.486,P=0.001;左眼F=26.168,P=0.000)、左侧卧位下(右眼F=14.829,P=0.000;左眼F=7.371,P=0.009)眼压升高的幅度要高于健康人。结论体位对眼压的测量存在影响,侧卧下的眼压明显高于坐位及平卧位下的眼压,在开角型青光眼患者这种差别更加明显。
Objective To measure the intraocular pressure ( IOP) in different sleep positions and compare with IOP in the sitting position.Methods Perspective study.Thirty-two patients with primary open angle glaucoma ( POAG) and 28 normal subjects had IOP measured in the sitting position and then again in the supine , right lateral decubitus ( right-lateral ) and left lateral decubitus ( left-lateral ) positions with a Perkins applanation tonometer.IOPs then were measured again in the sitting postion after 1, 5 and 10 minutes.Two-way ANOVA was used to compare IOP readings in the different positions among the two study groups.Data were shown as mean ±standard deviation.Results In normal subjects , the IOP values of the right eye were (17.5 ±3.8) (sitting), (19.3 ±3.1) (supine), (21.7 ±3.7) (right-lateral) and (21.5 ±3.7) mmHg (left lateral) (1 mmHg=0.133 kPa).The IOP values of left eye were (18.4 ±3.0) (sitting), (19.3 ±3.1) (supine), (20.7 ±2.9) (right-lateral) and (22.8 ±4.0) mmHg (left lateral).In the POAG patients , the IOP values of the right eye were ( 17.9 ±3.7 ) ( sitting ) , ( 20.6 ±4.6 ) (supine), (26.1 ±7.1)(right-lateral) and (26.3 ±5.9) mmHg (left-lateral).The IOP of the left eye in these positions were ( 18.2 ±3.6 ) , ( 20.0 ±4.1 ) , ( 25.6 ±6.1 ) and ( 25.7 ±6.0 ) mmHg, respectively.The IOP under the right-and left-lateral positions were higher than that in sitting and supine in both groups.The IOP increases in all positions for POAG patients were significant higher than in normal subjects.The IOP decreased rapidly after returning from the supine to the sitting position.The IOP values at 1 minute, 5 minutes and 10 minutes after returning to the sitting position were not significantly different than the original sitting.Conclusions The IOP in lateral decubitus positions is significantly higher than the IOP in sitting and supine positions.These differences are greater in POAG.
